Preferred Compass Directions in Initial Orientation of Homing Pigeons

Gloria Montenegro,Rosanna Ginocchiomination of such a plane orientation on other experiments suggests that mechanisms connected with the upper field of vision are specialized for polarization plane detection. Evidence that pigeons can perceive and discriminate ultraviolet light is mentioned. Finally reference is made to the widespread forebrain projections of olfactory input.

John R. Dodson,A. Peter Kershawrs the sun’s . as the source of light, rather than direct rays from the sun itself, as Menner had done. The sharp definition of the shadow, its extended linear contour, its proximity to the image of the horizon, and its position within the area of highest retinal resolution would all facilitate precise observation of the sun.

John R. Dodson,A. Peter Kershawction opposite to that of the test releases and transported in an iron container showed a dramatic difference in their initial orientation with respect to the control birds transported in an aluminum container. This suggests that magnetic stimuli perceived during the outward journey may also be involved in orientation.
