Many studies have been conducted to research the ways in which ravens and corvids learn. Some have concluded that the brains of ravens and crows compare in relative size to great apes. The encephalization quotient (EQ) helps to expose the similarities between a great ape brain and a crow/raven brain. This includes cognitive ability.
Jerison (1973) has suggested that the degree of brain encephalization (the ratio of brain size to body size, EQ) may correlate with an animal's intelligence and cognitive skills. [30] Corvids and psittacids have higher EQ than other bird families, similar to that of the apes. Among the Corvidae, ravens possess the largest brain to body size ...
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 ...

Some of the largest brain-to-body ratios in birds, especially of the telencephalon, that part of the brain responsible for cognition, are found in the Psittaciformes (parrots) and Corvidae (crows, ravens, jays, magpies, and allies), both members of the Australaves. [23] Indeed, the parrots and corvids are unique among birds for their large ...
