Leucolia violiceps
| Conservation status | Common within its range, numbers probably stable. |
|---|---|
| Family | Crows, Magpies, Jays |
| Habitat | Near tidewater, shores. Generally found close to the immediate coastline. Often along open beaches, rocky shores, tidal estuaries, coastal ponds, inshore islands. Also forages in woods and fields close to shore. Only occasionally moves to fields several miles inland. |
Forages mostly while walking on ground or in very shallow water; also sometimes forages in trees. May concentrate at salmon runs along with other birds. Flies up into the air carrying mussels, and drops them on rocks to break them open. May store food on territory and retrieve it later.
4-5. Dull blue-green to gray-green, blotched with brown and gray. Incubation is by female only, about 18 days. Young: Fed by both parents, and sometimes by one-year-old "helpers." Age when young leave the nest not well known, probably close to 4 weeks.

Omnivorous. Seems to feed on anything it can find in its habitat, including fish, crabs, shellfish, carrion, garbage, various insects, berries, nuts, seeds, and birds' eggs (especially in seabird colonies).
Usually solitary in nesting, not in colonies. Offspring from previous year may remain on nesting territory of adult pair; these "helpers" assist in mobbing predators, may or may not assist with feeding the nestlings. Nest site is usually in fork of tree or shrub; sometimes placed on the ground (sheltered by rocks) on islands. Nest (built by both sexes) is a bulky platform of sticks, bark, plant fibers, and mud, lined with softer material such as grass, animal fur, and rootlets.
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.
The Mexican Duck is now its own species, and the Northwestern Crow officially gets lumped with American Crow.
Some species have figured out that, when released from the right height onto a hard surface, even nuts or shellfish can make a (sort of) easy meal.
The Canadian corvid is a social media star, entertaining and educating people through his various mischievous deeds.
