Don Edwards San Francisco Bay National Wildlife Refuge
This is a comprehensive field guide to the all known bird species that preside or migrate through this Refuge.
Fox sparrows
The Fox Sparrow (Passerella iliaca) is a large American sparrow. It is the only member of the genus Passerella, although some authors split the genus into four species (see below).
Dark-eyed Junco
The Dark-eyed Junco (Junco hyemalis) is the best-known species of the juncos, a genus of small grayish American sparrows. This bird is common across much of temperate North America and in summer ranges far into the Arctic. It is a very variable species, much like the related Fox Sparrow (Passerella iliaca), and its systematics is still not completely untangled.
Nelson's Sparrow
The Nelson's Sparrow (Ammodramus nelsoni) is a small sparrow. This bird was named after Edward William Nelson, an American naturalist. Formerly, this bird and the Saltmarsh Sparrow were considered to be a single species, the Sharp-tailed Sparrow; because of this it was briefly known as Nelson's Sharp-tailed Sparrow.
Swamp Sparrow
The Swamp Sparrow (Melospiza georgiana) is a medium-sized sparrow related to the Song Sparrow.
White-throated Sparrow
The White-throated Sparrow (Zonotrichia albicollis) is a passerine bird of the American sparrow family Emberizidae.

White-crowned Sparrow
The White-crowned Sparrow (Zonotrichia leucophrys) is a medium-sized sparrow native to North America.
Spotted Towhee
The Spotted Towhee (Pipilo maculatus) is a large New World sparrow. The taxonomy of the towhees has been debated in recent decades, and formerly this bird and the Eastern Towhee were considered a single species, the Rufous-sided Towhee. An archaic name for the Spotted Towhee is the Oregon Towhee (Pipilo maculatus oregonus).
California Towhee
The California Towhee (Melozone crissalis) is a bird of the family Emberizidae, native to the coastal regions of western Oregon and California in the United States and Baja California Sur in Mexico.
Savannah Sparrow
The Savannah Sparrow (Passerculus sandwichensis) is a small American sparrow. It is the only widely accepted member of the genus Passerculus. Comparison of mtDNA NADH dehydrogenase subunit 2 and 3 sequences indicates that the Ipswich Sparrow, formerly usually considered a valid species (as Passerculus princeps), is a well-marked subspecies of ...more ↓
