Avian behavioural neuroscience: past, present and future perspectives

A survey of avian brain-behavior conference reports of the last 25 years reveals that neither the avian species studied nor the types of scientific questions asked have changed very much since the first such conference report in 1974. The birds studied tend, for the most part, to be pigeons, chickens, quail, and canaries. Because of the growing interest in avian vocalization and its neural control, one recent conference featured studies of canaries, zebra finches, and budgerigars. The topics of investigation at these conferences largely have involved sensory systems, mostly sensory and sensorimotor mechanisms with a heavy emphasis on vision and audition, as well as studies of learning and memory. Future research should expand the range of orders and species of birds studied so as to shed light on evolutionary trends within Aves as a whole. The scope of behavioral questions asked also should be broadened to include topics of neuroethological interest.
