The testing of intelligence in birds is therefore usually based on studying responses to sensory stimuli. The corvids ( ravens , crows , jays , magpies , etc.) and psittacines ( parrots , macaws , and cockatoos ) are often considered the most intelligent birds, and are among the most intelligent animals in general.
Results from this study suggest that current evidence for general intelligence is weak in non-human animals. [130] The general factor of intelligence, or g factor, is a psychometric construct that summarizes the correlations observed between an individual's scores on various measures of cognitive abilities.
The birds were tested on their ability to distinguish benign from malignant human breast histopathology images and could even apply what they had learned to previously unseen images. However, when faced with a more challenging task, they reverted to image memorisation and thus showed little generalisation to novel examples.
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 ...
Bird cell size is on the other hand generally smaller than that of mammals, which may mean more brain cells and hence synapses per volume, allowing for more complex behaviour from a smaller brain. [4] Both bird intelligence and brain anatomy are however very different from those of mammals, making direct comparison difficult. [25]
Corvids display remarkable intelligence for animals of their size, and are among the most intelligent birds thus far studied. [5] Specifically, members of the family have demonstrated self-awareness in mirror tests ( Eurasian magpies ) and tool-making ability (e.g. crows and rooks [ 6 ] ), skills which until recently were thought to be ...
Irene Maxine Pepperberg (born April 1, 1949) is an American scientist noted for her studies in animal cognition, particularly in relation to parrots.She has been a professor, researcher and/or lecturer at multiple universities, and she is currently an Adjunct Research Professor at Boston University.

Studies in bird behaviour include the use of tamed and trained birds in captivity. Studies on bird intelligence and song learning have been largely laboratory-based. Field researchers may make use of a wide range of techniques such as the use of dummy owls to elicit mobbing behaviour, and dummy males or the use of call playback to elicit ...
