We’d had some sprinkles, but the first real rain came Thursday & Friday, about two inches, and set the secondary drainage flowing across the near meadow again.  Creek was up and a little turbid, but the flow in the grass was crystal clear.   Today, I finally photographed a common (supposedly) species of butterfly around here, which I’d never been able to catch in the lens.

During migration and winter we have a lot of birds in the grass–birds that fly up and dive down a little distance away, birds that fly up and perch in bushes, birds that fly up and away and dive down over there. Most of them are sparrows of some kind.    Today one of the “divers” posed long enough for me to note salient characteristics and even get some slightly blurry pictures–good enough for an ID:

Forgot to mention yesterday that though I had heard a White-crowned Sparrow call in the yard a few days ago, I hadn’t spotted one until yesterday evening, up in the dry woods.  I came into the south end of the dry woods trail and startled some White-winged doves, who flapped off with their usual noisy behavior, but one smaller bird just hopped to the top of a cactus and sat there.

Some grasses should be planted just for the way they look with sunlight slanting through them in the fall.

This is one.  It’s one of the Muhlys, but I don’t know which.

Our on the land with visitors yesterday, I spotted a new fly (new to me):

That spotted abdomen was very obvious with the naked eye.   It’s a similar pattern to a spotted jumping spider we have (also white spots on black) and until I saw it fly I was thinking  “There’s another P. audax, never saw one on heath aster before.”   The “face” and antennae are the same golden color as the wings.

Species lists are now live on the website.  When you mouse over the Species List, three choices appear: birds, plants, and “zoology” (which in this instance means non-bird wildlife.)

And each of these lists has three pictures of representative species up there on the top green line.

So if you’re been wondering what we have…there it is.

The annual GBBC sponsored by Cornell University and the Audubon Society is our big bird census activity of the year.    Usually I spent 1-2 hours in each of four sites on the land, but this year (since I’m under orders not to overdo as I recover from pneumonia)  today’s observations at least will all be literally “yard” ones.   So far that’s only eleven species….but my “special bird” in the year, the female Pyrrhuloxia, is still here.   (Usually I see a really interesting bird the day before the count starts, and then not again until afterwards.)

Anyone who’s never participated should consider doing so…it’s fun and it contributes useful information on bird distribution in winter.   There are maps, updated constantly, showing where observations have come from.

If you have land, you have equipment (if it’s no more than a shovel, a clamshell posthole digger, and a fence tool.)    And equipment fails.

I went out today to check the water at both Fox and Owl, put out more feed for the winter-resident birds, and change the memory cards in the two game-cams.  We got those last spring (well, we borrowed a friend’s for a month to try it out) and they’ve been very helpful.   They have a feature that lets you enter a security code so the camera won’t work for anyone else and they have a digital display that has a variety of messages and lets you see that you’re entering the security code correctly.

About two months ago, the display began to “break up”–not all  the pixels of all the letters would show.  The camera still worked, though, and I could still enter the code.   I thought maybe the batteries were running low, so I changed them…but the display still looked spotty.  It’s gotten much worse in the last month (I  change out the memory cards on the last weekend of the month) and today I was unable to get the first camera to accept the code and go back to work.  The second did it, but if it goes the way of the other, it won’t work after the next changeout.

Just in case the local store had old, not strong batteries, I’ll buy new batteries at a store with more turnover, but I’m afraid some internal chip may be degrading for some reason.   It continued to take pictures (I’ve looked at what’s on the memory card–perfectly good video and still pictures, which is why I doubt it’s the batteries.)  These cameras are supposed to be able to handle any outdoor setting and until this happened I was pleased with them and hoped to order a couple more.

Observing wildlife–and the sign they leave behind–is one of the satisfactions of having some land. It’s also a necessary part of our wildlife management program. Census is one of the seven essential activities under the Texas Parks & Wildlife private lands wildlife program.

This makes sense–if you don’t know what you have, or (roughly) how many of it, you can’t manage it very well.

Cameras help with observation even when the animal isn’t there: photographing tracks, scat, nests, etc., can document the presence of something you don’t often (or ever!) see. So can simple interventions. We discovered that animals regularly used the paths we mowed for ourselves and the planks we put across muddy dips for our own convenience. In wet weather, they left footprints; they often left scat. One great horned owl neatly dropped two regurgitated owl pellets onto one plank. Read the rest of this entry »

I’ve started working on a long-term project to define who eats what and is eaten by whom. Published sources are not as much help as you might think, since they’re not really local and the local mix of food sources varies from both historical record (we have different plants, in different proportions, and thus different proportions of animals for the meat-eaters to prey on) and from published sources set in a different area.

It’s being every bit as difficult I suspected it would be. Critters do not all come and pose in front of the camera with an array of their food sources so consumption can be documented. Nor are they limited to the foods we put out. Killing a lot of native critters to do stomach content analyses (a very accurate way of finding out what *that* individual ate, but non-reproducible in that individual) isn’t something I want to do, or have the time and expertise to do anyway.
