Abstract
Homing pigeons, trained over increasing distances up to a maximum of 56 kilometers, were exposed intermittently to cold for a total duration of 132 hours. Concurrently a trained control group of similar size, paired by age with the test group, was kept at 24oC ambient temperature. After the period of exposure was complete both groups were flown over the 56 kilometer distance of the training course and their individual times to home were recorded. All birds returned to the coop. A significant impairment of homing performance was observed in the cold exposed birds relative to that of the controls.
