The Barn Swallow Habits
One sure sign of summer for anyone who enjoys bird watching, is this bird flying back and forth to any open barn or outbuilding in the country. This bird spends more time in the air then almost any other land bird. DescriptionThe bill is very short. Dark blue-black above with a dark rusty throat. The rest of the underparts are a buffy or pale rusty. Mating HabitsSwallows are generally monogamous, males mating with a single female. Although rare, males sometimes will pair with 2 females.Paired males will aggressively defend the small area around the nest and guard his mate from other males that might attempt to copulate with her. Nesting HabitsBoth the male and female bird build the nest, usually in the morning and making up to 1,000 trips to collect mud.Although this bird originally nested in caves and on rocky cliffs, the barn swallow was quick to take advantage of man-made structures. Today these birds nests only in association with man-made structures. The nest is a cup of mud pellets lined with grass and feathers, built under eaves of buildings, resting on a beam or some projection in barns, under bridges, in culverts, or occasionally in a niche on a cliff. The female lays 3 to 8 white eggs that are spotted with reddish brown. The eggs are incubated for 14 to 16 days and the young will leave the nest in 18 to 23 days. Two broods a season may be attempted. Feeding HabitsThese birds feed on flying insects and feed on the wing. During the breeding season these birds will feed in pairs and fly at a low altitude, generally over fields and water.During the non-breeding season they will feed in small, loosely formed flocks. HabitatBird watchers can look for Barn Swallows in open country and marshes, especially near barns, outbuildings, bridges, and culverts.
