After reading the section about the canyon tree frog (Hyla arenicolor) in my old Field Guide to Western Reptiles and Amphibians by Robert Stebbins, I had to read it aloud to you. Doesn’t it just make you want to get out and find canyon tree frogs? Stebbins not only wrote the field guide, but did all the illustrations as well. And if your interest is piqued, there is an updated 2018 edition.
Two other valuable field guides for us herpers, expert and otherwise. (I’m the latter)
A Field Guide to Amphibians and Reptile in Arizona, Holycross, Brennan, Babb. This one rides in our truck.
Arizona’s Amphibians and Reptiles, A Natural History and Field Guide, John C, Murphy and others This one I pull off the shelf when I get home.
Kids, collect the whole set!
The photos are mine.
