Article: Dream vacation

Something needs to be done with this laundry room

This year I managed to wrangle some extra vacation from work. I get the entire month of October off. It’s a rare opportunity that I decided to waste by working on the house.

We’ve been in this house about eighteen years and the one room I have ignored completely is the laundry room. I hate spending time in there possibly because I hate doing laundry. However, I am going to assume it’s because the room is ugly and if I change the room I’ll change myself.

At first I just thought I’d paint it a bright color. It is dirty white now and a coat of yellow paint might be just what it needs. But isn’t yellow both predictable and boring? To spice it up, I could paint the cabinets red. I stood in the doorway and stared at the coffin-like rectangular room. I could paint a red sun in the far corner and put a few red rays across the walls. It would still be mostly yellow with red cabinets. My imagination soared.

Of course the room needed a new floor. The current floor is sheet linoleum and has curled up along the edges ever since we lived here. I’m tired of that. So new linoleum. But what color? Red would be too overpowering. Yellow didn’t seem right. Maybe blue, then it would be like sun shinning on water. Or green, sun on the grass.

I started talking over my laundry room vision with my husband. I told him I want to get rid of the freezer that takes up one large corner of the room. It is full of food we’re never going to eat. We don’t need it anymore since the kids moved out. Rick agreed. To my surprise, he added that we should get a new washer and dryer.

So far I hadn’t really contemplated doing anything expensive. A new washer / dryer moves us into a different category. I wasn’t sure I wanted to go there. Strangely, Rick was adamant about it. Our current set is old and functions poorly at best but they almost seem like part of the family. If we got new ones, maybe they would be more energy efficient. Maybe they would be quieter. Maybe they would be a color to match the new walls and floor. That last thing got my buy-in, we need a new washer/dryer.

The next time I had to do laundry, my mind viewed the laundry room in all its new glory. I decided to take before and after photos. I stood in the hallway snapping the photos when my eyes wandered to the hall itself. Because of Rick’s disability, he often puts his hand on the wall to steady himself. Years of this means that the walls are filthy. I’ll need to paint the hallway too.

Something inside me clicked and suddenly it seemed the whole house needed modification. I remembered that I originally planned to use stencils to put falling leaves near the ceiling in the family room. I could do that in October. That would require getting a really tall ladder since the ceiling is sixteen feet at its peak. While I’m up there I should change the light bulbs that have been burned out for the last year. And clean out the cobwebs in the high corners.

While I’m working in the family room, I should get the sheet rock repaired from when we had a plumbing leak two years ago. That reminded me that there is another sheet rock repair job to do in the kitchen. And maybe I should replace the wallpaper. I guess I need to take some more “before” pictures.

Suddenly a month doesn’t seem that long. I must be dreaming to think I can get all that done.

Article: A capybara on MySpace

Screen capture of Caplin the Capybara's MySpace page


I belong to a writing group that meets twice a month. All the people in the group are writing novels. It’s a big ambition, ridiculous for the most part. I can live with that. We all have to have dreams. At each meeting we have thirty seconds to answer a random question about our writing. The question is supposed to help break the ice and reveal something about ourselves. This last week, we gave our responses to, “Do you have a blog?”

I was surprised that only I and one other woman had blogs. This dearth of internet savvy puzzled me. I guess most of my writing compatriots are older but even so, this is the twenty-first century isn’t it? And aren’t blogs a type of writing? Shouldn’t people who like to write be writing blogs?

It’s true that most blogs are pretty boring. Even blogs written by people who know how to write and have written on great topics, even those blogs tend to be so devoid of meaning that you wonder how they can say so little in so many words. Maybe it’s because people think it’s really interesting to write about their own lives, as if they are special or unique in some important way, which is almost certainly not true.

My blog is not like that. I’m as boring as the next person, maybe even more so, but my blog isn’t about me, it’s about my pet capybara, Caplin.

Those who know, know that lots of pets have blogs. Caplin’s blog, (I write in her “voice”), is on her MySpace page (www.MySpace.com/CaplinRous). MySpace is a hotbed of animal blogs. Most animal bloggers are dogs and cats, probably just as boring as people. But nearly all groups of animals are represented. One of Caplin’s MySpace friends is a snake. The snake has lots of snake MySpace friends. Caplin doesn’t have any capybara MySpace friends.

The thing about MySpace, blogs, YouTube and the like, is that you need to have something unique to say, but not too unique. For example, a pet capybara apparently doesn’t attract many readers. Most people don’t know what a capybara is, and if they do, they don’t think about searching MySpace to become friends with one. The reptile crowd is one up on the capybaras in internet presence and communication.

While Caplin’s MySpace provides information about capybaras, it could also be used by psychology students as an example of an 1obsession. Along with blog entries, I’ve got photos and videos of Caplin up there. I did a full customization on her page while my personal page has virtually nothing. Nearly every day I feel compelled to add something, a blog entry, a photo, a video. I do nothing to my own page. I want to share Caplin with the world.

The world isn’t looking. I’m not just guessing that, I know it for a fact. I can see how many people have viewed Caplin’s page and altogether it’s less than 250. Probably most of those hits are me. And she only has seventeen friends. Is it possible to be a nerd and an outcast on MySpace? I don’t want Caplin to suffer that kind of humiliation.

Maybe that’s why my writing friends don’t blog. Maybe they don’t have an animal to take the fall for them. With no pet to hide behind, their own lack of popularity would be exposed. For example, I am somewhat humiliated that, while Caplin isn’t exactly popular, she still has more MySpace friends than I do. Luckily I don’t have a delicate ego--or I’m living vicariously through my capybara.

Article: Not my birthday

The second photo out of my new camera. Caplin sitting on my lap.


It’s not my birthday but I got a present anyway. I bought it for myself, which is the best way to be sure to get something you like. I bought my present over the internet, quick and easy, and everything seems available.

What I bought is a fancy-schmancy new camera. It’s a digital SLR alot like my old one except that technology has moved on and this is the new and improved version. I bought the camera for a trip to Rick’s niece’s Bat Mitzvah. I wouldn’t actually have bought a camera for that, I don’t like photographing people. But when I decided to drive up to Denver, well, you never know what you’ll see and my old camera just did not seem up to the task.

As can be expected when ordering online, the camera didn’t actually arrive in time for the trip. It was waiting for me when I got home. I would have been more excited but the drive back from Denver took longer than I’d planned. It was almost two o’clock in the morning and I had work the next day. So the camera spent one more day sitting on the table in its unopened box.

The next day when I got home from work I was too tired to look at it. I needed to get some sleep after all that hard driving. The camera spent another day in its box.

But Wednesday when I got home, I spirited the magical package off to my room. Sitting at the chair in front of my computer, I sifted through the contents. Wow that camera looks nice. It has a lot more controls than my old camera. I’m sure I have no idea how to use it.

I’m also sure I have no intention of reading the manual. I pried the documentation from its shrink wrap and opened to the first page. The heading read, “Preventing Serious Injury or Death.” That just makes the whole manual seem stupid. How many people could possibly have been killed by a camera? I suppose it’s possible that if you swung it hard at someone, maybe a baby with a soft skull, and you hit them just right, but who can take that threat seriously?

So I set the manual down, pulled out all the contents of the box and set to work. There were a few things I figured I already knew how to do. This camera takes the same battery as my old camera, so I knew how to charge the battery and install it in the camera. The new camera is the same brand as my old one so it has the same lens mount. I knew how to attach a lens to the body and I even had a lens to attach. The memory card installed the same way also.

That was the end of the easy tasks. The next thing to do was put the shoulder strap on. The mounts on the camera body were obvious. The straps themselves seemed pretty straight forward. And yet, it was not so. I was forced to open the manual again. Naturally that didn’t help. It turned out one of the little plastic keepers had to be used in a particular orientation that was not obvious. Given a 50-50 chance, I’d chosen the wrong way.

Then I turned on the camera. It came up with a screen for setting the date and time. I fiddled with the controls. I want the date and time to be right so I couldn’t move on to actual photography until I fixed this. Sadly, I realized I would have to open the manual and start reading. Annoyingly, the information on setting the date and time doesn’t appear in the manual until page 39. I didn’t read those first 38 pages but they got in my way.

All that done, I was finally ready to take my first photo. Caplin, my two month old capybara, was sleeping on my lap so she provided the obvious subject. It was hard focusing on something so close so I had to lean back in my chair to get enough distance. I snapped the shutter and examined the image on the LCD. Blurry. I put the lens on autofocus and tried again. The second image came out much better but still nothing to write home about.

I hope I’m not actually going to have to read the manual before I can get good photographs. For some reason I have all the time in the world to take pictures but absolutely no time to learn how to do it.

Article: Total eclipse of the moon

Lunar eclipse during initial partial phase

Seems like everyone is always complaining about how hot it is in Texas during the summer. But that’s one of the things I love about Texas, especially the summer nights. What could be better than standing in the warm night air and drinking in the star light? Central Texas is great for amateur astronomers.

Actually, I’m kind-of lying, the warm air is not really that great for astronomers. Cool air holds less water and is therefore clearer than warm air and better for stargazing. However if, like me, you are not willing to stand outside in the cold, then it doesn’t matter how clear cold air is. That is what makes Central Texas summers perfect for people like me.

I was standing outside in the warm, moist morning air at 4:30 Tuesday morning to view the total lunar eclipse. I had my camera propped up on some pillows on my husband’s car since I wasn’t able to find a working tripod. The horses were out for the night and had nothing better to do then poke me with their muzzles to see if food would appear. And slowly the moon disappeared. The horses were completely unimpressed.

A lunar eclipse occurs when the shadow of the Earth falls on the surface of the moon. Since the moon is visible to half the world at any time, it’s about the easiest celestial event to witness. As the shadow moves, the bright face of the full moon gradually darkens. When you think about it, that’s amazing. You can actually view the relative movements of the Earth and Moon.

Looking closely as the eclipse progressed, I noticed that the boundary between light and dark was not a clean, sharp line. This fuzziness provided a mental contrast with memories of stark images from lunar landings. Even though I understood the phenomenon was due to diffusion of sunlight passing through the Earth’s atmosphere, it was still surprising to see.

Gradually, the entire moon fell into shade and the full glory of the eclipse manifested. The shadow of the Earth is not completely black. Some sunlight is scattered as it passes through the thin veil of the Earth’s atmosphere. If viewed from the moon, the Earth would appear to be ringed in fire, the red-orange color of infinite sunsets and sunrises. That diffused light falls on the darkened moon making it shine a dim but beautiful firebrick red.

The next lunar eclipse that will be visible in the United States is in February of 2008. Since the sun and the moon are on opposite sides of the Earth every month during the full moon, you might wonder why there isn’t an eclipse every month. This is because the orbit of the moon does not lie exactly in the plane of the Earth’s orbit around the sun, it’s about five degrees off. This is just enough to cause the moon to slide above or below the Earth’s shadow during most full moons.

One of the great sites of the internet is space.com. There’s a wealth of information there for anyone interested in astronomy. Go to http://www.space.com/imageoftheday/image_of_day_070829.html for some excellent images from this week’s eclipse. Another good site is www.MrEclipse.com. That site includes tables showing when and where to expect both lunar and solar eclipses and tips for photographing eclipses. None of the tips includes using pillows, pushing horses out of the way or living somewhere where the night air is like a warm blanket rather than a slap in the face. Obviously the tip section could use some expansion.

Article: Lessons from the Austin Zoo

Prairie Dog at the Austin Zoo (looks a little fat)

I often drive the stretch of Hwy. 290 leading from Dripping Springs to Austin. Along that road is a sign that always catches my attention, an arrow pointing down Circle Drive with the words “Austin Zoo.” I love animals and I love zoos but somehow I never had the time to stop. This weekend, I decided to finally go and to bring my son and his family along.

Celeste, who is eight, was excited about going to the zoo. She’s a cat person and really wanted to see the big cats, especially the tigers. The rest of us wanted to see the pair of adult capybaras the zoo was reputed to have.

Zoos these days all have missions. Of course one mission is to educate the public about the beauty and diversity of life on Earth. In addition to that mission, the Austin Zoo is a rescue zoo. Over 90 percent of their 300 animals have been rescued. A sign at the entrance admonishes visitors not to keep exotic animals as pets. Well that put a stop to me telling them I have a pet capybara.

Still, I understand their point. The zoo gets around 200 requests per year to take unwanted animals. People don’t always consider the long term commitment they are entering into when they get a pet. Even with dogs and cats, few consider whether the animal will fit into their lives in the five, ten or even fifteen years that the animal will live. Local animal shelters are full of abandoned pets who have outlived their owners’ interest.

Responsible pet ownership also involves selecting a pet that you have the time and facilities to care for. Most people can accommodate a dog or cat but not many could care for a bear, a tiger or an anaconda. Surprisingly, according to the Austin Zoo web site, there are more tigers in Texas than anywhere else in the world. Some are in zoos, some in “roadside attractions,” some are pets and others are at game ranches waiting to be “hunted.”

Those are the obviously bad choices for pets. There are less obvious ones. I might as well go through my own pets as examples.

Firstly, I have horses. Horses aren’t like most pets, they retain value throughout most of their lives. But horses live a very long time and toward the end they typically can’t be ridden. I lost a horse this summer who was twenty-nine years old. She’d had only very light use the last five years of her life, occasionally taking small children for short rides. I have the land to retire a horse. People who are spending $300 per month for board are much less likely to keep a horse past its useful life. Those horses end up going to slaughter.

I also have reptiles. For my son Philip’s first birthday, I got him a young leopard tortoise. It’s a gift that lasts a lifetime. Leopolda is now at least twenty-eight years old and weighs fifty pounds. I have structured my yard around a large tortoise. I have a good sturdy fence she can’t see through, a nice pond for water, no poisonous plants, and several fruit trees. In 1989 I gave Philip a Florida kingsnake. I still have that snake eighteen years later.

Before I bought my baby capybara, I considered whether I have the facilities for her. I have the nicely fenced yard that I built for Leopolda, including a pond. I want Caplin to be an indoor / outdoor pet but if that doesn’t work out and if she can’t just stay in the yard, I have a couple of pastures with wire mesh fence that I can configure for capybara use.

So we went to the Austin Zoo to take a look at their capybaras and compare their behaviors to Caplin’s. We wondered if she’d still be as friendly when she gets big and will she still make the cute noises. We ran into the general curator, Jim Carroccio, out at the tiger enclosure and asked about the capybaras. Jim told us that the zoo’s pair had died of old age a couple of years previously. We asked about capybara personality and Jim characterized them as “cow-like.” I think Caplin is going to prove him wrong. She’s already got a ton of personality

Article: Taking the long way

The AmerScot Inn, a B&B where I stayed in Stow, MA

I have a saying most people might not agree with but which suits me fine: if it’s worth going, it’s worth going the long way. Application of this motto provides glimpses into local culture and scenes that are completely missed when traveling direct routes or suffering confinement to major highways. It also makes me late.

This past weekend, I had the chance to put my travel paradigm into action. I found myself staying at a nice little bed and breakfast in the small town of Stow about an hour outside Boston. I travel quite a bit for work but seldom end up someplace that’s not completely urban. Stow is decidedly non-urban.

The AmerScot Inn (http://amerscot.com) provided a nice jumping-off point for my little adventure. Friday morning I had an excellent breakfast prepared by Doreen Gibson, the innkeeper, and followed by a short meeting with a potential customer. Then my day was free. All I had to do was get from Stow, Massachusetts to Bangor, Maine, a trip that takes about four hours on the major highways.

My natural proclivity in the area of indirection was given a boost when the customer advised me of a beautiful route along the New Hampshire side of the Maine / New Hampshire border. He warned that it was considerably longer. But I had all afternoon! So what if I got there at 6:00 instead of 4:00? Still plenty of time to enjoy a leisurely dinner and a long chat with my nephew in Bangor when I arrived.

Of course there’s no point taking a scenic route unless you stop to admire the scenes. Which I did. There was the adorable little town of Sandwich about half-way up the state. I stopped to look in a local art gallery and found a wonderful watercolor of marine invertebrates that I am going to regret not buying for years.

A little farther on, a sign pointed me to covered bridge #54. I had never seen a covered bridge so naturally I had to go. Number 54 turned out to be the Durgin Bridge, originally constructed in 1844 but apparently the current incarnation dates from 1869. Still, you don’t find bridges like that in Texas.

Near the New Hampshire / Canada / Maine intersect lies the town of Conway. That place must be a major tourist destination because I hit stop-and-go traffic well outside of town. When I parked my car to take a photo of some flowers with tree-covered mountains for a backdrop, a little tourist train put a stop to the go part of stop-and-go as it crossed the road between the tightly packed cars. I eyed the train enviously. If only I had time to ride it. Yet by this time I realized my arrival in Bangor was going to be a little later than six o’clock.

On the Maine side of the border I encountered a giant statue of Paul Bunyan in Rumford. The largest Paul Bunyan statue is actually in Bangor and I’d already seen that but this one nice too. Still no Babe the Blue Ox, which seems like a shame.

I didn’t make it into Bangor until after 10:00 pm, much later than I expected. Still, I saw a lot of things I never would have otherwise. Tired as I was, I did not regret my route. However, if I ever get a chance to do that particular drive again, I think I’ll take two days. And I’ll buy that watercolor in Sandwich.

Article: Bats rule the world

A flying fox bat takes off from its tree roost in Mysore, India

Last weekend I visited the most amazing location. I went to the place with the largest concentration of mammals anywhere in the world! I didn’t have to journey to the African Rift Valley or the rain forests of the Amazon. I didn’t even have to leave Texas. In fact, I only traveled about fifty miles from my home in Buda.

Maybe it’s not surprising that the largest concentration of mammals is composed of members of one of the most diverse mammalian groups, the bats. Bats, in the order Chiroptera, are only outdone in terms of numbers of species by the rodents. There are over 900 species of bats comprising about one fifth of all mammalian species. The bats at the world’s largest colony at Bracken Cave just north of San Antonio are Mexican free-tailed bats, the same species as the colony under the Congress Avenue bridge in downtown Austin.

Bats can be divided into two groups, the small microbats and the large macrobats. The microbats have a nearly world-wide distribution and include all of the 47 species of bats found in the US. These bats use echolocation (or sonar) and feed mainly on insects. The macrobats, also known as flying foxes, live in a swath from Australia, through Southeast Asia and Africa, including Madagascar and many oceanic islands. Flying foxes do not use echolocation and most species feed on fruit. As their names suggest, microbats are generally considerably smaller than megabats. The largest of the flying foxes have a wingspan of up to six feet. The smallest of the microbats, the bumblebee bat of Thailand, weighs less than a penny and is considered to be the world’s smallest mammal.

When I was a little girl living in Panama, we used to sleep inside netting, mostly to escape the mosquitoes but also to prevent vampire bats from biting our toes at night. The threat from vampire bats is not really the bite, which doesn’t hurt at all since the bats provide a local anesthetic, or the loss of blood since each bat drinks only about two tablespoons. The real issue is rabies, which is more common in vampire bats than in other bat species, as can be expected by their feeding habits. The United States is well outside the range of vampire bats and about one in five hundred bats here carries rabies. In the US, an average of one person per year contracts rabies from a bat.

Aside from the prospect of rabies, bats have a large impact on human life. The colony at Bracken Cave consumes an estimated 200 tons of flying insects each night. Many of those insects are crop pests. Several plant species such as mango, clove, guava and avocado depend on bats for pollination. The large flying foxes are also hunted for food throughout much of their range.

Watching the bats emerge from Bracken Cave is an awe-inspiring experience. For a couple of hours before sunset, the bats swirl around just inside the mouth of the cave. It takes several minutes to notice that the dark rocks on the outer lip of the cave are not dark at all, what you are really seeing is thousands of densely packed bats. Just before the sun goes down a few brave bats spiral out of the sinkhole containing the cave opening and fly off in lonely solitude. As the sun disappears, a thin trickle of bats winds its way across the darkening sky. Well before full-dark that trickle has become a torrent with a seemingly endless flow of bats streaming forth. The wind from their wings causes the nearby trees to sway as if a gentle breeze were blowing.

Central Texas is also fortunate to be the home of Bat Conservation International (BCI) which was founded in Austin in 1982. BCI is dedicated to bat conservation world-wide and owns nearly 700 acres surrounding and including Bracken Cave. Tours such as the one I attended are offered periodically throughout the summer. Visit their website for information on how to join a tour.

Article: The cutest rodent in the world

Close-up of a baby capybara named Caplin

I’m writing this article with a capybara sleeping on my lap. Capybaras are the world’s largest rodents with adults reaching 150 pounds. Caplin weighs about four pounds but she’s only fifteen days old. She has already doubled in weight since she was born.

Caplin is my new pet but she’s not the only pet rodent to have inhabited this house. When my daughter was a teenager she had a pet rat named Rainbow. Properly treated and maintained, rats make excellent pets. They’re smart, clean and personable. They can identify people and can learn tricks.

Capybaras don’t look like rats, they look like another rodent commonly kept as pets, guinea pigs. Capybaras have big, square heads, short bodies and no tails. Also like guinea pigs, capybaras are native to South America. They range from Panama down the eastern side of the continent. Unlike guinea pigs, capybaras are semi-aquatic. They have partially webbed toes to allow them to move easily on moist or muddy ground.

My kids and I went to the Los Llanos region of Venezuela earlier this year. We saw hundreds of wild capybaras sitting on the roads, wading in the swamps or swimming in the multitude of lakes. The setting looked idyllic but life in the wild is hard for capybaras. They share the swamps with caiman, crocodiles and anacondas all of whom enjoy a delicious meal of capybara. Those are some fearsome predators. And that’s not counting the occasional jaguar.

Of course, the wild capybaras main threat comes from humans. In addition to the standard issues of habitat destruction, capybaras are also hunted. This hunting is exacerbated by the fact that capybara are considered legitimate to eat by Catholics during the forty days of lent, the only mammal to have that honor. During our stay in Los Llanos, our guide told us that capybaras in that area are only eaten during lent and hunting is prohibited the rest of the year, but this is probably not true throughout their range.

Capybara gestation takes between five and six months which seems like a long time for a rodent. A typical litter contains five babies who are born with fur and with their eyes open. In the wild, baby capybaras stay with their mothers for up to eighteen months. Even though they nurse, baby capys eat grass from their first day of life.

Pet capybaras are not easy to come by. We searched the web and could find only one breeder in the United States, fortunately located not too far away in south-western Arkansas. When we contacted her we found she didn’t have any babies for sale and that her sales were booked for many litters in advance. Luckily she pointed us to one of her previous customers who had just had a litter. His location in Nacogdoches was fortunately even closer. By the time we got there less than a week later, only one of the original five babies remained.

We’ve had Caplin five days and can already see she will make a great pet. She loves being scratched or having her ears rubbed. She litter box trained herself. She’s still a bit skittish when she thinks someone is going to catch her but otherwise she will climb all over you, chew on your hair and take food or a bottle from your hand. When she’s happy she makes quiet chirping or purring sounds, more high-pitched than a cat’s.

The large size of a mature capybara probably means Caplin will have to move out to the backyard when she gets bigger. I’m hoping she’ll help with the mowing and maybe even cut back on the plants growing in my pond. Cute, friendly and useful, capybaras make the perfect pet--I hope.

Here’s a link to a YouTube video of Caplin getting her chin scratched.

Article: A home for termites

Reproductive flight of subterranean termites

A couple of weeks ago I was outside standing in a light drizzle waiting for the vet to come look at one of my horses. Due to the overabundance of rain this year, insect populations have thrived. This fact asserted itself on me most obviously through the tiny gnats that persisted in landing on and walking across every inch of my exposed skin. More annoying than even the gnats, the constant buzz of mosquitoes and their too-frequent bites kept me busy swatting the air.

The vet took forever to arrive. I had nothing to do but stare down the drive looking for her. As I did, I noticed that there were a lot of flying insects mixed in with the raindrops. Small and colorless, I assumed they were moths and paid little attention to them. It wasn’t until my daughter Coral pointed out that they were coming out of a hole in the ground that I took an interest. I went to see what was going on.

Rising from a hole amid the caliche of the driveway, emerged a constant stream of winged insects. Each new arrival took to the air as soon as it was clear of the hole. Around them bustled smaller, whitish, wingless insects. I bent down to get a closer look. I hadn’t recognized the winged alates but I immediately knew the others to be some of the most destructive insects in the world: subterranean termites. As I watched hundreds of them were taking their nuptial flights, seeking to start their own colonies.

Termites are fascinating creatures. They are the only fully social insects that are not in the hymenoptera, the order containing wasps, bees and ants. Termites belong to their own order, the isoptera. They are most closely related to cockroaches. In fact, some roaches eat wood in the same way termites do. Uniquely, termites and the aforementioned roaches, have intestinal symbiotes to digest cellulose.

Like all insects, termites have to shed their exoskeleton in order to molt. The exoskeleton actually includes the lining of the gut and so when termites shed, they lose all of their intestinal contents, including the flagellates without which they cannot live. For this reason every termite larva and every adult after molting must be re-inoculated with the correct intestinal flora. Termites do this by anal feeding. It is thought that this dependence may have the impetus that drove termites down the path to social behavior.

As I watched the seemingly endless stream of reproductives helped out of their nest by soldiers and workers, I was reminded that most termites are completely blind, only the queens and kings even have eyes. In their mounds, termites live in constant darkness and they never forage in the open. This behavior allows termite infestations in houses to persist for long periods before they are noticed.

Looking around I could see that plenty of potential for new colonies to start on or around our house. In fact, the colony that I was observing apparently lay under the driveway, the one place on our property where the availability of cellulose seems limited.

On the other hand, we also have hundreds of trees, especially along the banks of Garlic Creek which passes just in front of the house. These trees are constantly shedding small branches and leaves and the creek imports significant driftwood from upstream when it rains. Nature has a way of taking care of that stuff so that I don’t have to and that is termites. In addition, termites are a valuable food source to many birds including a family of woodpeckers that I’ve enjoyed observing this summer.

Like everything, termites have good and bad aspects when viewed from a human perspective. I guess I’m going to have to have the house inspected because the termites cannot be allowed to feed on it. On the other hand, termites are part of the natural environment and watching their nuptial flight was a unique experience and a glimpse into their nearly invisible lives. As long as they know their place, I think we can get along.

Article: Lady Bird Johnson is my hero

Lady Bird Johnson advocated planting wildflowers
along roadsides like this one in Hays County, TX

I just learned that Lady Bird Johnson died today. In a way unlike any other First Lady, Ms. Johnson made a big impact on my life. It still amazes me how much she did for this country and how much we all owe her.

I can’t remember the first time I heard the slogan, “Keep America Beautiful.” When I was young it became part of the mantra of our nation. In some vague way I knew Lady Bird was responsible for that saying but as I grew up it didn’t seem important. Or perhaps more accurately, it didn’t seem innovative or insightful, it just seemed obvious.

One day when my son was a baby, I sat on the porch talking to my mother-in-law and her sister. As they played with Philip they reminisced about when their own children were young. One thing they said that stuck with me all these years is that driving across the southern US they had used some of the first disposable diapers. And when one got dirty, they simply tossed it out the window.

Neva and Goldie weren’t bad people. As they explained, it did not occur to them not to throw the diapers out. They didn’t know how long those diapers would lie there. They didn’t think about what it would look like if everyone did what they were doing. And then Lady Bird came on the scene and began her beautification projects. It was the first time anyone had spoken to them about littering. And she changed their habits.

Lady Bird also fought the plague of billboards taking over American highways in the 1960s. I can remember when billboards lined nearly every road. If limiting those signs was all Lady Bird did, I would still be greatly in her debt. Removing the billboards has made traveling much more pleasant. Imagine what our highways would look like now without her work. Driving through the Hill Country would not provide rugged vistas dotted with wildflowers, it wouldn’t provide vistas at all, just advertisements.

Speaking of wildflowers, Lady Bird Johnson initiated the movement to line roadsides with wildflowers. All those people taking Easter photos of their kids in the bluebonnets have Lady Bird to thank for their photo-ops.

In 1965, President Lyndon Johnson spoke on highway beautification, one of Lady Bird’s signature issues, saying “a new and substantial effort must be made to landscape highways to provide places of relaxation and recreation wherever our roads run.” He was speaking about flowers and billboards but I think the sentiment should be revisited today.

Continuing Lady Bird’s efforts means striving to include beauty and recreation in all highway improvements. The road bond bill that recently failed to pass in Hays County is a good example of what we shouldn’t do. Roads are not just about cars getting from one place to another, aesthetics and recreation must be considered too. Instead of a five lane thoroughfare with plain grass verges, maybe we should consider three lanes, native trees and hike and bike paths. Travel, beauty, relaxation and recreation.

Lady Bird Johnson provided an example for all Americans. She was a great woman who had tremendous influence on the way this country is experienced by all of us who share in her legacy. Let’s learn from her example and keep her spirit alive not just in our words but in our actions.

Article: In pursuit of painted buntings

Not all birds are created equal

About a month ago I was out horseback riding when a strikingly colored bird flitted by. I caught only a glimpse knew immediately that it was a painted bunting, Passerina ciris. I’m no bird expert but it doesn’t take a rocket scientist to identify a male painted bunting.

The Peterson Field Guide, Birds of Texas begins its description of this bird with “The most gaudily colored American bird.” There’s no mistaking it. The chest and belly of the male are as bright red as any cardinal, the head more brilliantly blue than a blue jay and there is a startling patch of yellow-green on its back blending to dark green feathers on the upper wing. No child would color a bird so fancifully.

I followed the painted bunting I’d spotted until it perched in the uppermost reaches of a large juniper (also known as “cedar”). Against the overcast sky, the primary colors of the bunting’s plumage disappeared into black silhouette. It soon flew to a farther location. Since it had started raining--again--I suspended the chase. But while unsaddling my horse, I was surprised to see that same bird chase a tiny hummingbird off the apex of a skeletal tree.

In the morning I was a woman on a mission. I hoped the painted bunting was staying near the house and I was determined to get a photograph. Nearly ever year, we see one or two of these birds but they disappear almost as soon as they appear. I imagined they didn’t like the mix of vegetation around our property and were headed to the Hill Country where an elusive bird could remain unseen by human eyes. I needed to get my photograph before the bird moved on.

So I grabbed my camera and dragged an old lawn chair out to the juniper where I’d seen the bird the previous day. I sat as still as I could while mosquitoes bit me and abundant gnats crawled all over my face and arms. It was worth it though because the ploy worked. Within a half-hour I had some half-way decent photographs.

Through my camera’s viewfinder, I watched the sparrow-sized bird sing. What a beautiful song it was! Longer and more complex than the songs of typical birds on our property, the painted bunting’s song has the distinction of containing no repeated notes or phrases. I quickly learned to recognize it.

The next morning I heard that song while feeding the horses. I rushed to get my camera. Slowly, quietly, I followed the auditory trail. Soon I spotted the bird perched, again, on the ultimate pinnacle of a juniper. Looking up, I should have seen the brilliant red of its belly. Instead the backlighting caused the entire bird to appear black

The next day I heard the song again and made another mad dash for my camera. The bird flew from the top of a near juniper to one in a dense copse of trees. However, I noticed something strange--that distinctive song was coming from more than one location. I had at least two of the magnificent birds living with me!

On the following day, I carried my camera out while I fed the horses and was rewarded with another sighting. Again the bird was near the top of a juniper but at least this time I could see it was red. As I walked to the front pasture I heard at least two other birds calling. Suddenly it seemed I could hear that song everywhere.

Apparently painted buntings are one of the more common birds on our property. I’m not sure if this was always true. It’s possible I just never noticed them before. Despite their almost ridiculously distinctive colors, small birds that perch on the tops of trees are easily overlooked. Or it could be that mulching of many of the junipers on our property this spring changed our land into prime bunting habitat. Either way, the little birds are now driving me crazy. I carry my camera everywhere--when it’s not raining--constantly on the lookout for buntings in photogenic poses. Someday I will get that perfect photo.

Article: The history of a horse

Camp had another relapse. We had her put down July 3rd, 2007. This photo was taken a couple of hours before her death. As you can see, she was curved to one side again and by this point was having trouble standing. A few carrots alleviated her suffering somewhat.

Camp and other horses romping in the pasture.

No matter how much you expect some things, they still come as a surprise. I suppose this is generally the case when the thing you’re expecting is not what you want. I had one of these unpleasant surprises last month when I went out to the pasture one evening.

My friend Sheldon and I had been working on making riding trails in the back part of my land. As sunset approached, we stumbled, hot and tired, back to the house. Lazy as I am, I decided it’d be easier to let the horses graze than lug hay out to their pens. Sheldon went to make the release while I secured hay and grain against equine marauders.

When I finished what I was doing, I looked out to watch the horses lope to the far corner of the pasture to where, in their minds at least, the grass is the greenest. They are such beautiful, graceful animals, I never tire of watching them. But immediately I knew something was wrong. My oldest horse, Camp, was literally stumbling along behind the others.

I grabbed a halter, called to Sheldon and we went after her. My heart sank. Camp wasn’t just lame her entire body curved to one side. From head to tail her spine traced an arc of a circle. Her hind legs seemed to want to go one direction while her head went another, resulting in an uncoordinated side-passing locomotion. When I put the halter on her she nearly stumbled into me.

I bought Camp for $700 fifteen years ago as a birthday present for my daughter Coral. Coral was eleven and Camp was thirteen. She was the perfect horse. Always calm, would do anything and go anywhere, never spooked and yet was willing to run all day if that’s what Coral wanted. Camp had the speed to make it worthwhile.

Over the years her smooth gaits and gentle disposition made her the perfect horse for kids and novice riders as well as the more experienced. A few years ago, I looked her up on the AQHA web site. I was surprised to learn she had an ROM (Register of Merit) in racing back from when she was a two-year-old. And she sold for nearly $20,000 as a yearling.

What was even more surprising was that her record was marked “deceased.” Further investigation revealed that the AQHA marks horses as dead when they reach twenty-five unless they hear otherwise. While Camp was starting to show her age, she was a long way from dead. Just last month she was under saddle with my son’s eight-year-old daughter on her back.

Then came her injury. Camp has struggled through the last month, making an amazing recovery. After last Friday’s vet check, our family let out a collective sigh of relief. On Sunday evening I decided she could go out to graze with the other horses, just as she was going to on the night she fell ill. But when I went out to release her, Friday’s healthy Camp had been replaced with the Camp from a month ago. She’d relapsed.

Now we’re waiting on test results that may, or may not, reveal what’s wrong. The options are four types of encephalitis--including West Nile--or a brain tumor. The prognosis isn’t good any way you look at it.

Twenty-nine is ancient for a horse. Even so we’re not prepared to let her go…not yet. We’ll try to see her through this. As long as her spirits are good and she seems happy, we’ll keep working. She’s done so much for us, especially for Coral, that we can’t fully repay that debt. But part of the payment is care for her current illness.

That’s the easy part. I hope we have courage for the hard part. We don’t want her to suffer and mercy is something we can afford our pets. If Camp knew it, she’d be glad she is livestock and not a human being.

Update 2007/06/28: Test results are back. Camp has a herpes viral encephalitis. There is no treatment and once contracted the horse has the disease forever. However it may go into remission but this is unlikely in a horse her age. We are starting her on oral steroids to control the symptoms. She's currently doing fairly well and as long as the symptoms remain mild, we'll watch and wait.
