Sacramento Mather Airport, California, July 2013

Resident in the Central Valley of California and adjacent foothills.
A restricted-range species, prior to 2004 locally common or abundant. The West Nile virus has reduced the population by around 50%.

Taxonomy

This is a monotypic species[1].

It is closely related to Black-billed Magpie and may even be conspecific with the latter.

Habitat

Oak savannas, oak woods, riverside growth, ranches, and suburbs. With the loss of natural habitats, they have moved to vacant city weedy yards and lots.

Behaviour

A strongly colonial species, they live communally throughout the year, feeding, socializing, and mobbing predators. It has become a city bird but avoids heavily populated areas. However, in some places they obviously do not mind people at all.

Diet

Omnivorous. Feeds on insects, mice, bird eggs, nestlings, small reptiles, carrion (especially roadkill) and human handouts.

Vocalisation

A raucous qua-qua-qua and a querulous quack.

Breeding

Breeding season from December to May. They lay 5-8 blotched, olive green eggs in a large, domed stick nest; breeds in colonies in tall trees usually so overgrown with mistletoe that it is often hard to detect the nests.
