The brown-necked raven has been observed hunting lizards in complex cooperation with other ravens, demonstrating an apparent understanding of prey behavior. [71] The California scrub jay hides caches of food and will later re-hide food if it was watched by another bird the first time, but only if the bird hiding the food has itself stolen food ...
Corvidae is a cosmopolitan family of oscine passerine birds that contains the crows, ravens, rooks, magpies, jackdaws, jays, treepies, choughs, and nutcrackers. [1] [2] [3] In colloquial English, they are known as the crow family or corvids.
In the Company of Crows and Ravens was written with and illustrated by Tony Angell. [1] They discuss the ways that crows are like humans, and the many different ways that humans have treated crows. [1] In Gifts of the Crow, Marzluff and Angell documented how intelligent crows are, with both anecdotes and research. [2]
The Australian raven is also somewhat closely related to the Torresian and little crow, although not as closely related as it is to the other raven species. Initial single gene genetic analysis of the genus using mitochondrial DNA showed the three raven species to belong to one lineage and the two crows to another.
Researchers Wascher and Bugnyar tested four ravens on their behavioral response to inequity in a token-exchange task (they also tested crows at the same time). [166] Two ravens never refused food in any condition. Overall, the ravens refused to accept the low-quality reward more often in the inequity condition than in the equity condition. [169]

A raven is any of several larger-bodied passerine bird species in the genus Corvus. These species do not form a single taxonomic group within the genus. There is no consistent distinction between crows and ravens; the two names are assigned to different species chiefly based on their size.
The family Corvidae includes crows, ravens, jays, choughs, magpies, treepies, nutcrackers, and ground jays. Corvids are above average in size among the Passeriformes, and some of the larger species show high levels of intelligence. Nine species have been recorded in Nevada. Pinyon jay, Gymnorhinus cyanocephalus; Steller's jay, Cyanocitta stelleri
