Mammals and birds have dramatically more neurons in their forebrain and cerebellum than reptiles, and neuron numbers have scaled up significantly only four times in more than 300 million years of ...

The extremely tight match between the 'real' and the 'digital' brain volumes surprised the researchers. "We used computed microtomography to scan the bird skulls. This allows us to digitally fill ...

Navaornis had a larger cerebrum than Archaeopteryx, suggesting it had more advanced cognitive capabilities than the earliest ...

Carrion crows and humans line up patiently, waiting for the traffic to halt. When the lights change, the birds hop in front of the cars and place walnuts, which they picked from the adjoining ...

That some of us still throw the term “bird brain” around as a barb points to poor cognition in our own species, not theirs.

The ancestors of living birds had a brain shape much different from other dinosaurs (including other early birds). This suggests that brain differences may have affected survival during the mass ...

The brains of birds, reptiles, and mammals evolved independently, reveal two recent studies. These findings revolutionize our understanding of brain evolution. The pallium, a crucial brain region for ...

The insult “bird brain” should probably be retired. Eurasian jays can pass the marshmallow test, some species have ”culture”, and even extinct avians like the dodo were probably smarter ...

13, 2025 — New research has revealed that birds, reptiles, and mammals have developed complex brain circuits independently, despite sharing a common ancestor. These findings challenge the ...

"In this study, we developed a new statistical method to better quantify context dependence in individual birds and start to understand how it is wired in the brain." The researchers analyzed ...
