Habbitat

Tree Swallows breed in fields, marshes, shorelines, wooded swamps, and beaver ponds throughout northern North America, preferring to live near bodies of water that produce multitudes of flying insects for food. 

 

Food

Tree Swallows live on a diet of insects, though they occasionally capture other small animals and may eat plant foods during bad weather when prey is scarce. They feed from dawn to dusk in sheltered areas full of flying insects, usually foraging no more than 40 feet from the ground. 

 

Behavior

Tree Swallows are highly social, forming large migratory and wintering flocks; and pairs often nest close together, particularly where nest boxes are numerous. Agile fliers, Tree Swallows tend to glide more than any other swallow species. They bath by flying low over the water and skimming their bodies against the surface, then rising quickly while shaking off droplets.
