Professor Scott MacDougall-Shackleton, Director of Advanced Facility for Avian Research at UWO, gave a presentation on birds and how they respond to changes in weather and daylight, and how they cope with the winter.
Some bird behavior is guided and influenced by the length of daylight. This is one of the factors that influences migration. Birds migrate based partially on day length. Hours of daylight let them know it is time to start their spring and fall migrations. Even caged birds display migratory restlessness by fluttering their wings and moving back and forth inside their cages during migration time for their species.
