Cognitive ornithology: the evolution of avian intelligence

Area of Science:

• Comparative psychology
• Evolution of intelligence
• Avian cognition

Background:

• Primates are traditionally studied for intelligence evolution, while birds model associative learning.
• Corvids and parrots exhibit ape-like intelligence due to large forebrains, complex social structures, and extended development.
• Ornithological studies often overlook avian intelligence, focusing instead on behavior and ecology.

Purpose of the Study:

• To review recent studies on avian cognition.
• To contrast anthropocentric and adaptive specialization approaches.
• To argue for a combined approach in studying avian intelligence.

Main Methods:

• Review of recent scientific literature on avian cognition.
• Analysis of studies on episodic memory and theory of mind in birds.
• Comparison of cognitive abilities between corvids, parrots, other birds, and apes.

Main Results:

• Corvids and parrots demonstrate cognitive abilities comparable to, and in some cases exceeding, apes.
• Evidence suggests convergent evolution of complex cognition in species with disparate brain structures.
• The study highlights the potential for shared neural patterns between birds and mammals.

Conclusions:

• A combined approach integrating anthropocentric and adaptive specialization methods is most effective for avian intelligence research.
• Corvids and parrots represent key species for understanding the evolution of complex cognition.
• Convergent evolution likely explains the emergence of advanced cognitive traits in birds and mammals.
