Boreal Toad (Anaxyrus boreas) is a medium-sized (6-10 cm) toad with dry, warty skin. They are distributed along western North America from southern Alaska to Baja California. In New Mexico, they are only found in north-central Rio Arriba County between 2,774-3,200 m in the San Juan Mountains at Canjilon, Trout, and Lagunitas lakes. They inhabit a wide range of aquatic habitats from desert springs to mountain wetlands and will occur at elevations as high as 3,658 m. Because they lack vocal sacs, they do not call, but will occasionally make small chirps, especially when in duress.
