Birds can also have twice the neuron packing density of primate brains, in some cases similar to the total number of neurons in much larger mammal brains, for a higher unit mass per volume. This suggests that the nuclear architecture of the avian brain has more efficient neuron packing and interconnections than mammal brains.
The first list shows number of neurons in their entire nervous system. The second list shows the number of neurons in the structure that has been found to be representative of animal intelligence. [1] The human brain contains 86 billion neurons, with 16 billion neurons in the cerebral cortex. [2] [1]
Corvids display remarkable intelligence for animals of their size, and are among the most intelligent birds thus far studied. [5] Specifically, members of the family have demonstrated self-awareness in mirror tests ( Eurasian magpies ) and tool-making ability (e.g. crows and rooks [ 6 ] ), skills which until recently were thought to be ...
Magpies are birds of various species of the family Corvidae.Like other members of their family, they are widely considered to be intelligent creatures. The Eurasian magpie, for instance, is thought to rank among the world's most intelligent creatures, [1] [2] and is one of the few nonmammalian species able to recognize itself in a mirror test. [3]

Encephalization quotient (EQ), encephalization level (EL), or just encephalization is a relative brain size measure that is defined as the ratio between observed and predicted brain mass for an animal of a given size, based on nonlinear regression on a range of reference species.
Bird Image Species Family Maximum height Details Rüppell's vulture: Gyps rueppellii: Accipitridae: 11,300 metres (37,100 feet). [1] [2] Vultures use their excellent eyesight to scan the landscape below from a relatively static aerial position. Instead of flying over a larger distance, they use elevation to expand their field of vision. [3]
