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.
East Lawn Cemetery
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.
William Land Park
The large conifers and berry-laden shrubs and trees of William Land Park attract winter flocks of American Robin, Cedar Waxwing, Yellow-rumped Warbler, Dark-eyed Junco, and American Goldfinch. This is a good place to look for wintering Varied Thrush (under the redwoods), Red-breasted Nuthatch, Golden-crowned Kinglet, Townsend’s Warbler, Purple Finch and Pine Siskin.
Reichmuth Park
Reichmuth Park, for its size, is one of the great magnets for migrating landbirds in the Sacramento area. Sixteen warbler species have been recorded here, including all of the West Coast species plus Black-and-white Warbler, Northern Parula, American Redstart, Hooded Warbler, and Canada Warbler.
Greenhaven Lake
Public access to Greenhaven Lake has diminished to the point where it's no longer a great birding destination, but worth a check if you're in the area as in fall and winter, large flocks of Common Merganser, Ruddy Duck, gulls, Clark’s Grebe, Ring-necked Duck, Lesser Scaup, Canvasback, Bufflehead, Common Goldeneye and other water birds may be found.
Garcia Bend Park and Marriott Park
Garcia Bend Park is worth a visit in spring and fall to look for migrating landbirds in the riparian growth and Caspian or Forster’s Terns over the river. Marriott Park has large valley oaks that attract migrating warblers, vireos, tanagers and others in spring.
Chorley Park
Chorley Park is a small city park that harbors migrating land birds and nesting White-tailed Kite in spring. This area consists of weeds, willows, and cottonwood trees.
