Chat and Cardinal sing off. Other birds today: Phainopepla, cactus and canyon wrens, hooded oriole, G. quail, verdin, Anna’s and Costa’s hummers, Audubon’s and Townsend’s warblers, ladderback and Gila woodpeckers, black-headed grosbeak, and western tanager. The last two were chilling together ON THE SAME BRANCH. #birdnerd #birder #birdlist #birds (at Boyce Thompson Arboretum State Park)
