Red Spotted Toad

My water fountain has attracted a most amazing desert creature. I heard the trill of the Red Spotted Toad before I saw him. He was sitting on the edge of my fountain, calling for a mate. Amazingly enough, another toad answered the call from a few houses away. Where does he go during the day? Where has he been until now? How did he get across the desert to my fountain? Will wonders never cease?

The video is dark, but the audio sounds like the New England woods, not the Sonoran Desert.
