Learning multiple routes in homing pigeons
The aerial lifestyle of central-place foraging birds allows wide-ranging movements, raising fundamental questions about their remarkable navigation and memory systems. For example, we know that pigeons (Columba livia), long-standing models for avian navigation, rely on individually distinct routes when homing from familiar sites. But it remains unknown how they cope with the task of learning se...
متن کاملVisual lateralization and homing in pigeons.
The aim of our study was to analyse the components of visual lateralization in pigeon homing, a large-scale spatial task. In a series of 13 releases, birds were tested as binocular controls or monocularly with the right or left-eye covered. Occlusion of either eye had a significant effect on initial orientation and homing performance. Vanishing bearings were deflected to the side of the open ey...
متن کاملSensory Mechanisms Related to Homing in Pigeons
Besides having a well-developed vestibular system, pigeons possess a gravity and inertia sensitive system mediated by displacement of the viscera, presumed to stimulate mesenteric mechanoreceptors. Classical conditioning experiments confirm a sensitivity to atmospheric pressure changes. Failure to demonstrate a magnetic field orientation sensitivity in an instrumental conditioning situation is ...
متن کاملHoming of magnetized and demagnetized pigeons.
Homing pigeons appear to use the earth's magnetic field as a compass and perhaps as part of their position-finding system or 'map'. The sensory system they use to detect magnetic fields is unknown, but two current possibilities are some mode of response by the pineal organ or by the visual system, or it may be based on the magnetite crystals found in their heads. Three series of experiments to ...
متن کاملHoming of single pigeons--analysis of tracks.
The way in which homing pigeons find their home lofts is still obscure despite a long history of investigation. Since the work of Kramer & St Paul (1950a, 1952) and of Matthews (1951, 1953), it has been widely believed that some homing pigeons possess the ability to navigate. This belief is now based on the results obtained by many workers (see Schmidt-Koenig, 1965, for a critical review), whic...
