Do barn swallows reuse their old nests?

This natal philopatry often occurs even when old nests have been removed from a site. About 45 to 85 percent of pairs that have successfully raised a brood will reuse their old nests if they are still available and free of parasites. (Barn swallows are notorious hosts for disease-carrying parasites, a subject we’ll delve further into later.)

What is the difference between a male and female barn swallow?

Males are more boldly colored than females. Barn Swallows feed on the wing, snagging insects from just above the ground or water to heights of 100 feet or more. They fly with fluid wingbeats in bursts of straight flight, rarely gliding, and can execute quick, tight turns and dives.

Both parents also bring food to their young, and even sometimes an older bird from a pair’s previous clutch may come around to assist. Young barn swallows fledge the nest in 20 to 25 days but will remain close by for several weeks afterward. Some pairs will raise a second clutch in a single breeding season.

Do swallows reuse old nests?

Barn swallows may reuse an old nest, cleaning out some of the debris from the first brood and adding a new layer of mud to the rim. Other songbirds occasionally reuse a nest if it’s in good shape.
