This is by no means a comprehensive guide to the critters of Terlingua, but it highlights a few novel things:
The ubiquitous Turkey Vulture (Cathartes aura).
We didn't see any javelinas (collared peccary), nor were we particularly concerned - they're docile. Feral hogs are more vicious by far. But we were quite tempted to get the t-shirt. It at least inspires hikers to leave the wildlife alone!
Stuffed jackalope! I've never seen a plush jackalope - taxidermy may be pretty advanced on matters of the jackalope, but there's nothing quite seeing your beloved jackalope immortalized in a line of plush creatures. The scorpion still rocks, almost as much as the plush rattlesnake I'm so fond of.
When I saw this, I did a double-take. Many birds have been plush-ized, and many are kind of strange (the blue TY pelican comes to mind), but this was the first time I've ever seen a plush Aplomado Falcon (Falco femoralis).
...see? Even the tag says so! And what interesting timing.
