The barn swallow will mob intruders such as cats or accipiters that venture too close to their nest, often flying very close to the threat. [60] Adult barn swallows have few predators, but some are taken by accipiters, falcons, and owls. Brood parasitism by cowbirds in North America or cuckoos in Eurasia is rare. [6] [37]
Older males typically migrate first and leave the overwintering sites in late December or early January, followed by older females. Younger birds (first yearlings) typically arrive at the breeding grounds up to two months later. [19] Fall migration is also staggered, as birds head south when the breeding season is over.

The western house martin is similar in habits to other aerial insectivores, including other swallows and martins and the unrelated swifts, and catches insects in flight. [9] In the breeding areas, flies and aphids make up much of the diet, and in Europe, the house martin takes a larger proportion of aphids and small flies than the barn swallow. [9]
