Mesquite bloom

The warblers have arrived, feeding on the paloverdes. I saw a Townsend’s Warbler and a Yellow Warbler [no, Orange-crowned, see tomorrow’s entry] in the same tree on the west side of the wash, in full morning sun, showing off their markings (the Townsend’s has a bright yellow mask and breast, black eye patch with a yellow dot in the middle). Further down the wash in another paloverde a Wilson’s Warbler was feeding on the flowers, bright yellow with black cap.
