An individual from a huge chorus of:
It had rained 4-6 inches in this area the night before.
A chorus of Pseudacris clarkii, Gastrophryne olivacea and Spea multiplicata calling from a flooded field after 4-6 inches of rain the previous night.
A chorus of Spea multiplicata calling from this desert grassland area after 2 inches or rain the previous night.
Even here, late on a Sunday night, 20 miles from the nearest highways and traffic there is still anthropogenic noise! (Commercial plane flying over)
no boss, and passed the peanut butter-smell test
We were hiking down a trail in juniper/coastal sage scrub and heard what sounded like the far off revving of a chainsaw or ATV, or loud revving snoring. Looking up wondering what kind of weird bird it is we go around a corner and practically splash into a large puddle left by recent rains -- with a pair of mating toads. Nice to see they're sill around, though haven't seen them since.
Spea is a genus of North American amphibian commonly referred to as the western spadefoot toads. They differ greatly from true toads (those of the family Bufonidae) by having eyes with vertical pupils, no parotoid glands, and relatively smooth skin. Their most distinctive feature is a spade-like projection on their hind feet, from which their common name is derived. This projection enables spadefoot toads to dig in loose soils with ease.
