===Food and feeding===
[[File:Raven scavenging on a dead shark.jpg|thumb|right|Corvids are highly opportunistic foragers. Here, a [[jungle crow]] feeds on a shark carcass.]]
The natural diet of many corvid species is omnivorous, consisting of [[invertebrate]]s, nestlings, small mammals, berries, fruits, seeds, and [[carrion]]. However, some corvids, especially the crows, have adapted well to human conditions, and have come to rely on human food sources. In a US study of [[American crow]]s, [[common raven]]s, and [[Steller's jay]]s around campgrounds and human settlements, the crows appeared to have the most diverse diet of all, taking [[human impact on the environment|anthropogenic]] foods, such as: bread, spaghetti, fried potatoes, dog food, sandwiches, and livestock feed. The increase in available human food sources is contributing to population rises in some corvid species.<ref name = m&n2006/>

Some corvids are predators of other birds. During the wintering months, corvids typically form foraging flocks.<ref name = robertson2000 /> However, some crows also eat many agricultural pests, including [[cutworm]]s, [[Wire-worms|wireworms]], [[grasshopper]]s, and harmful weeds.<ref name = shadesfonight>Shades of Night: [http://www.shades-of-night.com/aviary/ The Aviary] {{Webarchive|url=https://web.archive.org/web/20060415190544/http://www.shades-of-night.com/aviary/ |date=15 April 2006 }}.
