This bird's habit of feeding on bayberries enables it to winter farther north than other swallows. It is the first of our swallows to reappear in the spring. Hole-nesters such as the Tree Swallow often face a housing shortage and must fight to get into, or keep, woodpecker holes or other sought-after nest sites. Man-made breeding boxes may help increase the numbers of these birds. The Tree Swallow almost invariably nests in the immediate vicinity of water. Several pairs once nested on a ferry boat that shuttled across the Saint Lawrence River, foraging on both the American and Canadian sides. Tree Swallows often enjoy playing with a feather, which they drop and then retrieve as it floats in the air. They gather in enormous flocks along the coast in fall, where they circle in big eddies like leaves caught in a whirlwind.
