In fact, crows and ravens seem to parallel our own evolutionary history as well as some behaviors we associate with being human, Ksepka said. "We found that birds, especially songbirds and parrots, have surprisingly large numbers of neurons in their pallium: the part of the brain that corresponds to the cerebral cortex, which supports higher cognition functions such as planning for the future or finding patterns. In fact, most birds pack in way more neurons per gram of brain tissue than other animals.

Songbird and parrot brains accommodate two to four times more neurons than rodent brains of similar weight, and around twice as many as some primate brains.

Most of a mammal’s neurons are found in the cerebellum. (CNN)Being called a "bird brain" may be closer to a compliment than an insult. Nevertheless, the macaw has more neurons in its forebrain -- the portion of the brain associated with intelligent behavior -- than the macaque. This has led many scientists to dismiss them as stupid.
