The Western Subspecies of Purple Martin is uncommon and declining, but the City of Sacramento is host to a few small breeding colonies that have adapted to nesting in “weep holes” under freeway overpasses.
If you have only a few hours to spare for birding on a winter weekend morning, you might want to visit East Lawn Cemetery on Folsom Boulevard in East Sacramento. Filled with winter residents, over the years, Townsend’s Warbler, Black-throated Gray Warbler, and Black-and-white Warbler have been found here in the winter.
