Edit: Found out it's a Texas Earless Lizard, and a male one at that. Cool!
Here's the ONE Golden-cheeked warbler we saw, though we heard more off in the distance. We'll have to come back in about a month which is closer to the time we went last year and saw lots of fledgeling warblers (and I forgot my camera that time, so I'd better not forget it again next time). Golden-cheeked warblers are one of the two federally listed endangered species that this wildlife refuge was created to protect, the other being the Black-capped Vireo which I've never seen before. They live in a different habitat in a different area of the refuge. Maybe next time I can try to find some vireos too.
