Chestnut-backed chickadees live on the west coast of North America, from Alaska to Southern California. They are common in parks and suburbs of the San Francisco Bay Area, where I have this backyard nesting box.
The female builds the nest, starting with a foundation of green moss and redwood bark strips torn from a nearby tree and animal fur or other fluffy material she can find nearby. She flutters her wings to form a nesting cup.
When ready, she lays one egg each night until she has a clutch of five or six. When she starts incubating them, she goes outside only to eat and drink. Her mate sometimes brings her food.
After two weeks of incubation, the first egg hatches. Initially the chicks are blind but not deaf. Both parents feed them frequently, chirping to let them know when food has arrived. The nestlings grow quickly and fledge about 3 weeks after hatching.
