Tree Swallows

The Tree Swallow is one of eastern North America's most familiar and common birds. It normally nests in tree cavities excavated by other species such as woodpeckers, but it also readily uses nest boxes. On its breeding grounds, the Tree Swallow is a favourite species for biologists to study.

Long Point Bird Observatory has conducted long-term monitoring of nesting Tree Swallows at three nest box "colonies," each containing 50-65 nest boxes. There were two study sites near Port Rowan (at the Port Rowan sewage lagoons, and adjacent to agricultural land at Mud Creek), and a third at the Tip of Long Point.

The objectives of this project were: (1) to provide a long-term record of Tree Swallows' breeding performance in relation to food supply and climate, (2) to provide other opportunities for research on breeding swallows, and (3) to provide training in field ornithology for students and volunteers.

This project was undertaken with the financial support of the Government of Canada.
