Interesting Fact: 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 bathe by flying low over the water and skimming their bodies against the surface, then rising quickly while shaking off droplets. ( https://www.allaboutbirds.org/guide/Tree_Swallow/lifehistory )
