We didn’t see very many herps (reptiles and amphibians) this summer, and I managed to get pictures of just three. At least they were all pretty charismatic.

Nice to see other inhabitants of the environment where your birds are being studied. What impact do herps have on the birds?
Cool question. For the juncos, snakes and large lizards might eat eggs, nestlings, and even unwary adults. More indirectly, some herps compete with the juncos for food, since both eat arthropods; others may benefit juncos by eating other junco predators like small rodents.
For birds in general, herps may be prey as well as predators: herons and egrets will eat frogs, and shrikes will eat anything.
I’m impressed by the red spot on the Alligator Lizard’s tongue: is that typical? Or did he just eat a lady bug?
Some photos of alligator lizards (courtesy of that great scientific authority, Google) have that red spot, some don’t. Alligator lizards have forked tongues that they use for chemosensing (smelling), like snakes; I can’t find any explicit mention of the red spot though. Any herp experts out there, please chime in!
