[1] Counting has traditionally been considered an ability that shows intelligence. Anecdotal evidence from the 1960s has suggested that crows can count up to 3. [2] Researchers need to be cautious, however, and ensure that birds are not merely demonstrating the ability to subitize, or count a small number of items quickly.
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]
First are listed birdwatchers with large life lists, which is based on the number of species of birds each of them has/had seen. Depending on the taxonomic viewpoint, there are 10,858 ( Clements V2023 ) or 11,032 ( IOC ver. 14.1 ) living bird species recognised.

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 .
In total there are about 10,000 species of birds described worldwide, though one estimate of the real number places it at almost twice that. [1] The order passerines (perching birds) alone accounts for well over 5,000 species. Taxonomy is very fluid in the age of DNA analysis, so comments are made where appropriate, and all numbers are approximate.
