Green Toad
Anaxyrus debilis
Summary 2
The North American Green Toad, Anaxyrus debilis,is a species of toad found in the southwestern United States in the states of Arizona, New Mexico, Colorado, Kansas, and Texas, as well as in northern Mexico in the states of Tamaulipas, San Luis Potosí, Durango, and Zacatecas.
In Bexar County, the Green Toad is found mostly in the Tamaulipan biotic province in the southern parts of the county. It is not common in the county and is usually not found in urbanized areas. They are rarely found on the surface except after very heavy rains where they may come out and breed irruptively in flooded grassland areas.
They are our smallest true toad species, with adults generally between 1-2 inches in length. Females get larger than males but don't exceed two inches in total length.
Call 3
The call of the Green Toad is a trill, as you would expect for a toad. But its diminutive size means it produces a high pitched trill. The call is more insect like than most other toad trills.
Here is the call of a male Green Toad from the lower Rio Grande Valley near Rio Grande City, Texas.

Similar Species 3
The Green Toads small size, dry skin and green color help distinguish it from any of our other local amphibian species.
The call of the Green Toad is a high pitched nasal trill that can sound similar to the nasal whine of the Western Narrow-mouthed Toad. Because the two species are both found in grassland habitats and are irruptive breeders after heavy rains, they are often heard calling together where the trilling nature of the Green Toad can help distinguish from the buzzy "meeeeh" of the Narrow-mouthed Toad. (Narrow-mouthed Toads are actually not "toads" in that they are in a different family than the true toads).
Here is a blog post comparing the calls of the two species - http://frogcalls.blogspot.com/2015/08/great-plains-narrowmouthed-vs-green.html
