Saw lots of these guys dead in the Greenhouse sadly.
Baja tree frog and CA tree frog calls. The 2 syllable calls (ribbit ribbit) are the Baja tree frog (Pseudacris hypochondriaca hypochondriaca) and the 1 syllable calls are the CA tree frog (Pseudacris cadaverina). It was dark and we turned off all flashlights and head lamps and I recorded these two calls in a stream where we had just seen and heard both species of tree frogs in the water. It was right next to the little bridge you can see on the map.
This deafening chorus contained:
Texas Toads (Anaxyrus speciosus)
Mexican Spadefoot (Spea multiplicata)
Couch's Spadefoot (Scaphiopus couchii)
Great Plains Narrow-mouthed Toad (Gastrophryne olivacea)
Spotted Chorus Frogs (Pseudacris clarkii)
It was painful to the ears to be amongst the frogs, particularly the Texas Toads.
A chorus of Pseudacris clarkii, Gastrophryne olivacea and Spea multiplicata calling from a flooded field after 4-6 inches of rain the previous night.
There were many choruses of thousands of this species in this area after 4-6 inches of rain the previous night.
Calling from this roadside during the early evening after heavy rains the previous night.
