An Indigenous Effort to Return Condors to the Pacific Northwest Nears Its Goal
The Yurok Tribe plans to soon reintroduce North America's largest bird to northern California, where the raptor hasn't soared for a century.

Corvus corax
Conservation status | Ravens disappeared from much of the east and midwest before 1900. In recent decades they have been expanding their range again, especially in the northeast, spreading south into formerly occupied areas. |
---|---|
Family | Crows, Magpies, Jays |
Habitat | Boreal and mountain forests, coastal cliffs, tundra, desert. Can live in a very wide array of habitats, from tundra above the Arctic Circle to hot desert areas of the southwest. Often in heavily forested country; may also live on prairies if good nest sites (on cliffs) exist nearby. |
Typically forages in pairs, the two birds sometimes cooperating to flush out prey. Searches for nests, to eat the eggs or young birds. An opportunist, taking advantage of temporary food sources. Does most feeding on the ground. Often feeds as a scavenger, searching for carrion or visiting garbage dumps. In northern Alaska (Pt. Barrow) in winter, seen feeding at dump under artificial lights.
4-6, sometimes 3-7. Greenish, blotched with olive or brown. Incubation is mostly or entirely by female, about 18-21 days. Male feeds female during incubation. Young: Both parents bring food for nestlings, and female broods them while they are small. Young leave nest about 5-6 weeks after hatching.

Omnivorous. May feed on practically anything, but majority of diet apparently is animal matter. Feeds on a wide variety of insects, including beetles, caterpillars, and others; also rodents, lizards, frogs, and eggs and young of other birds. Regularly eats carrion and garbage.
In courtship display, male soars, swoops, and tumbles in mid-air. Pair may soar high together; when perched, they touch bills, preen each other's feathers. Nest site is usually on ledge of rock cliff, or high in tall tree (especially conifer). May use same site year after year, adding material on top of old nest. Both sexes help build. Nest is a bulky basket of large sticks and twigs, with deep depression in center lined with grass, bark strips, moss, animal hair.
Audubon’s scientists have used 140 million bird observations and sophisticated climate models to project how climate change will affect this bird’s range in the future.
Zoom in to see how this species’s current range will shift, expand, and contract under increased global temperatures.
Choose a temperature scenario below to see which threats will affect this species as warming increases. The same climate change-driven threats that put birds at risk will affect other wildlife and people, too.

Surprisingly, lighter plumage isn't necessarily better in hotter climates.
Cade, who died in February, founded the Peregrine Fund and was pivotal to the re-establishment of the species in the United States.
