Hurter's Spadefoot (Scaphiopus hurterii) Dewitt County, Texas |
Like all Spadefoots (family Pelobatidae), Hurter's Spadefoot is a fossorial species that only comes to the surface after heavy rains. They breed explosively after those rains, the tadpoles develop quickly and they burrow down into the soil again until the next rain.

and here he is in action -
These Hurter's Spadefoot were recorded at the western edge of their range in Atascosa County, Texas.
In this area, their range overlaps with the western Couch's Spadefoot (Scaphiopus couchii).
The calls of the two species are superficially similar in that they are both a nasal "waaahh", but Hurter's Spadefoot call is shorter, given more rapidly and is descending in pitch throughout. It has almost a "doppler effect" sound. It almost sounds like someone trying to impersonate the sound of a race car going by very quickly.
Couch's Spadefoot call is slower and ascends before descending.

Beautiful page. We are looking for these this year in Arkansas after having 2 1/2 hours last night with 200 breeding Wood Frogs.
