Corvidae is a cosmopolitan family of oscine passerine birds that contains the crows, ravens, ... the Corvid's intelligence is boosted by their living environment ...
The corvids (ravens, crows, jays, magpies, etc.) and psittacines (parrots, macaws, and cockatoos) are often considered the most intelligent birds, and are among the most intelligent animals in general. Pigeons, finches, domestic fowl, and birds of prey have also been common subjects of intelligence studies.
Clark's nutcracker (Nucifraga columbiana), sometimes referred to as Clark's crow or woodpecker crow, is a passerine bird in the family Corvidae, native to the mountains of western North America. The nutcracker is an omnivore, but subsists mainly on pine nuts , burying seeds in the ground in the summer and then retrieving them in the winter by ...
It is one of the two largest corvids, alongside the thick-billed raven, and is the heaviest passerine bird; at maturity, the common raven averages 63 centimetres (25 inches) in length and 1.47 kilograms (3.2 pounds) in weight, though up to 2 kg (4.4 lb) in the heaviest individuals. Although their typical lifespan is considerably shorter, common ...
The cognitive abilities of the Eurasian magpie are regarded as evidence that intelligence evolved independently in both corvids and primates. This is indicated by tool use, an ability to hide and store food across seasons, episodic memory, and using their own experience to predict the behavior of conspecifics. [2]
Intelligence and social structures make most crow species adaptable and opportunistic. Crows frequently cause damage to crops and property, [53] strew trash, and transfer disease. In densely populated areas around the world, corvids are generally regarded as nuisance animals. [54]
New research suggests that some birds, such as those in the family corvidae, can rival primates and even humans in forms of intelligence. Much like humans, birds have enormous brains relative to the rest of their bodies. Ackerman highlights the complex social structures of avian society.
Alice Auersperg is an Austrian cognitive biologist specializing in the evolution of intelligence in birds.Her research is primarily focused on the physical cognition, play behavior, problem-solving and tool-making abilities in parrots and corvids.
