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]

The book explores birds as thinkers (contrary to the cliché "bird brain") in the context of observed behavior in the wild and brings to it the scientific findings from lab and field research. [2] 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 ...
