Ravens are smart - really smart and thus highly adaptible. In the Sonoran Desert of Arizona they are a frequent sight all year above 1000 m elevation soaring conspicuously and calling loudly. They range into the lower deserts visiting especially orchards and low mountains. They vary their diet with what is available. Road kill is a frequent dining spot as are freshly mown hayfields and even pecans and fruit. Picnic tables and garbage dumps, too.
West Nile Virus has hit these birds pretty hard; hopefully they will recover to their former numbers.
