Ridgway's Rail

About the Ridgway's Rail

Ridgway's rail (Rallus obsoletus) is a species of bird found principally along the Pacific coast of North America from the San Francisco Bay Area to southern Baja California, as well as in some regions of the Gulf of California. A member of the rail family, Rallidae, it is a large cinnamon-brown rail that lives in brackish tidal marshes and rarely flies. Its name commemorates American ornithologist Robert Ridgway.

This species is closely related to the clapper rail, and until recently was considered a subspecies. It has a long, downward curving bill and is grayish brown with a pale chestnut breast and conspicuous whitish rump patch. It is most active nocturnally and crepuscularly.

Typically cinnamon-brown in color, it is darker in coloration on the back. Adult coloration is variable, with several color morphs. The total length in adults is 32–41 cm (13–16 in), and weight ranges 160–470 g (5.6–16.6 oz). Males are about 20% larger than females. Size can vary by geographical location. Hatchlings are covered in black downy feathers.

Ridgway's rail forages along the ecotone between mudflat and higher vegetated zones and in tidal sloughs. Mussels, clams, arthropods... Wikipedia →
