California Clapper Rail
Vital Statistics

 

STATUS: Endangered

APPEARANCE: Gray-brown above with a buffy-cinnamon chest and a white patch under the tail. Grows to 13 to 19 inches long; males slightly larger than females. Long, slightly downward curving bill.

HABITAT: Salt marshes

RANGE: San Francisco Bay Area

FOOD: Worms, mussels, fish and other small invertebrates

BEHAVIOR: Have an extremely elusive nature, move quickly through marshes and take cover rather than fly away when frightened or bothered.

OFFSPRING: Build nests near tidal sloughs using cordgrass, pickleweed and other plants. Male and female birds share incubation and rearing of the 4 to 14 eggs; chicks are able to leave the nest soon after they hatch, but many remain with their parents for several weeks. Some rail pairs nest twice during the breeding season that begins in February and continues until August.

THREATS: Human development; predation by nonnative red fox, Norway rat and feral cats; pollution; and loss and fragmentation of salt marshes as a result of the draining, filling and diking of marshes in the San Francisco Bay Area.
