Birds communicate with their flockmates through song, calls, and body language. Studies have shown that the intricate territorial songs of some birds must be learned at an early age, and that the memory of the song will serve the bird for the rest of its life. Some bird species are able to communicate in several regional varieties of their songs.
The researchers suggest that this study may provide insight into how behaviors learned through imitation can still be selected for due to level of performance. Sewall explored the variation in learned bird songs in relation to social and genetic intermixing of families of red crossbills (Loxia curvirostra). [25]
The best known research technique in this area is the mirror test devised by Gordon G. Gallup, in which an animal's skin is marked in some way while it is asleep or sedated, and it is then allowed to see its reflection in a mirror; if the animal spontaneously directs grooming behavior towards the mark, that is taken as an indication that it is ...
Alex (May 18, 1976 – September 6, 2007) [1] was a grey parrot and the subject of a thirty-year experiment by animal psychologist Irene Pepperberg, initially at the University of Arizona and later at Harvard University and Brandeis University.
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.
Filial imprinting is not restricted to non-human animals that are able to follow their parents, however. The filial imprinting of birds was a primary technique used to create the movie Winged Migration (Le Peuple Migrateur), which contains a great deal of footage of migratory birds in flight. The birds imprinted on handlers, who wore yellow ...
Research associate Terry McGlynn works surrounded by taxidermy animals at the Natural History Museum in Los Angeles, where researchers are studying bird feathers to determine the effects of ...
Therefore, the identification and classification of animal behavior as being imitation has been very difficult. By the 2000s, research into imitation in animals had resulted in the tentative labeling of certain species of birds, monkeys, apes, and cetaceans as having the capacity for imitation.
