Sonora, Mexico Herp List
August 2017
I spent about a week in Sonora, Mexico with Matt Cage, Andrew DuBois, and a small horde of other herpers. Our main destination was around the picturesque town of Álamos in tropical deciduous rainforest habitat. We also visited Bahía de Kino on the coast and the area between Hermosillo and Yécora.
