Mourning doves

Wash still quite wet but not flowing. New bird call: a rising series of tweets followed by a trill on a lower note, ending with a flourish. Some kind of warbler perhaps (the Yellow Warblers I saw yesterday?). Three Cactus Wrens having some sort of fight, play, or love triangle: one calling from a tree, another from the top of a saguaro, joined later by a third. Also a thrasher. The ants are hard at work on the new leaves, leaving trails of green to their nests. A Sonoran Spotted Whiptail and a large Zebra-tail.
