Did you know that Barn Swallows once nested in caves across North America but now rely heavily on barns and farmland for nesting?
Barn Swallows are small, low-flying birds. In flight, they can be identified by their deeply forked tail and tawny underbelly, this is also the best opportunity to see the white spots on their tail! Barn Swallows can also be identified by their shining blue back that extends from their head, all the way to their tail. They also have a rusty brown chin and forehead, this is a great way to tell a Barn Swallow apart from their close and more abundant relative the Tree Sparrow which has a white underbelly and chin.
Barn Swallows are great pest deterrents and are often seen flying low above fields on the hunt for flying insects. In fact, Barn Swallows only eat flying insects, and rarely travel beyond 500 meters from their nesting sites to collect food. They are even said to eat hundreds of insects each day!2 Since these birds rely heavily on man-made structures to create nests, farmland and farm owners are vital to their survival.
