Cactus scar

On Monday I at last saw the Bewick’s Wren I’ve been hearing, also another sighting of the hawk. Got a better look at the breast and underside of the wings; mostly white, with speckling near top breast and leading edge of wings. I think it was an immature Redtail. Today I saw a female Ladder-backed Woodpecker and a Abert’s Towhee. The house finches were in full spring song.
