Trans-Pecos rat snakes were the species most commonly seen.
With several mobile homes (cabins) scattered over the hilly terrain, and having a herp-friendly owner, Wild Horse Station is a magnet for herpers and birders. Although Jake and I had failed to make reservations earlier, we had lucked out. Mrs. Hammer (owner) still had one unrented cabin. We rented it and decided on an afternoon nap to prepare us for a night of herping.
Although it had poured here the night before we arrived, the low pressure system had then been replaced by a high that was to persist for the 5 days we were in the Study Butte-Terlingua region. Weatherwise, things did not look overwhelmingly in our favor for snake movement. But after having driven 1500 miles with high hopes firmly entrenched, adversity is difficult if not impossible to accept.
So anyway, here we were, still with high hopes, at Wild Horse Station for 5 days. Luckily, our friends from last year, Charles and Wendy Triche, were in the next cabin so we could visit and commiserate.
The nights cooled quickly allowing the few snakes that were out and about to move shortly after nightfall. But let me tell you how bad conditions (I really don’t think it was our searching techniques!) were; on a 30-mile stretch of road where we usually see a dozen or more rattlesnakes of 4 taxa, in 5 nights we saw ZERO, and on that whole trip we saw only a half dozen Trans-Pecos rat snakes! Even the prey items, the pocket mice, kangaroo rats, and other desert rodents, were at an all time low.
The half dozen Trans-Pecos rat snakes,
Bogertophis subocularis, we found were all normals (no blondes, but Bob Hansen’ s group found a blonde the night after we moved northward—congratulations Bob and gang). The few variable ground snakes,
Sonora semiannulata, found were pretty but none were of the more colorful banded phases. And after dozens of runs and rock checks through prime habitat, finding our principal target taxon, a Chihuahuan lyre snake,
Trimorphodon vilkinsonii, remained only a dream.
Will there be a trip next year? Only time will tell. If so will it show better results. Only Mother Nature and Jupiter (the God of weather) can say.
Compared to some this variable ground snake was pretty bland.
My nemesis--a Chihuahuan lyre snake.
