Corvidae

Corvidae is a family of passerine birds that includes crows, ravens, rooks, jackdaws, magpies, jays, and nutcrackers. Its members are known for varied diets, complex social behavior, and strong learning abilities.

Crow: Crows are medium-to-large birds in the genus Corvus, found across much of the world. Crows are among the most widespread and familiar members of Corvidae.
Tool use by animals: Tool use by animals is the use of an external object to achieve a goal. Some corvids modify or select objects to obtain food.
New Caledonian crow: The New Caledonian crow is a Pacific island corvid known for making and using tools. Its crafted tools provide unusually clear cases of complex foraging behavior.
Bird: Birds are feathered, warm-blooded vertebrates that lay hard-shelled eggs. Corvidae is one family within the class Aves.
Raven: Ravens are large birds in the genus Corvus, distinguished from crows by their size and other traits. Ravens represent the family’s largest and often most imposing members.
Food caching: Food caching is the storage of food for later consumption. Many corvids hide food and use memory to recover their caches.
Western scrub-jay: The western scrub-jay is a North American corvid that caches food and may pilfer other birds’ caches. Its caching behavior has enabled influential experiments on memory and planning.
Passerine: Passerines are birds in the order Passeriformes, which includes more than half of living bird species. Corvidae belongs to this large order of perching birds.
Magpie: Magpies are long-tailed corvids, including black-and-white species in the genus Pica. Their striking plumage and long tails contrast with the typical crow-like silhouette.
Vocal learning: Vocal learning is the ability to acquire or modify sounds through experience. Corvid calls vary by species and can carry information within social groups.
