The legs are short, and their feet are adapted for perching rather than walking, as the front toes are partially joined at the base.

Behaviour

s in Nigeria attracted 1.5 million individuals. Non-social species do not form flocks, but recently fledged chicks may remain with their parents for a while after the breeding season. If a human being gets too close to their territory, swallows will attack them within the perimeter of the nest.

Diet and feeding

For the most part swallows are insectivorous, taking flying insects on the wing. Across the whole family a wide range of insects are taken from most insect groups, but the composition of any one prey type in the diet varies by species and with the time of year. Individual species may be selective, they do not scoop up every insect around them, but instead select larger prey items than would be expected by random sampling. In addition the ease of capture of different insect types affects their rate of predation by swallows. They also avoid certain prey types; in particular stinging insects such as bee

.

The swallows generally forage for prey that is on the wing, but they will on occasion snap prey off branches or on the ground. The flight may be fast and involve a rapid succession of turns and banks when actively chasing fast moving prey; less agile prey may be caught with a slower more leisurely flight that includes flying in circles and bursts of flapping mixed with gliding. Where several species of swallow feed together they will be separated into different niches based on height off the ground, some species feeding closer to the ground and others feeding at higher levels. Similar separation occurs where feeding overlaps with swift

. Old males benefit most from coloniality, since they are able to maintain their own nests and benefit from frequent extra-pair copulations.
Pairs of mated swallows are monogamous, and pairs of non-migratory species often stay near their breeding area all year, though the nest site is defended most vigorously during the breeding season. Migratory species often return to the same breeding area each year, and may select the same nest site if they were previously successful in that location. First-year breeders generally select a nesting site close to where they were born and raised. The breeding of temperate species is seasonal, whereas that of subtropical or tropical species can either be continuous throughout the year or seasonal. Seasonal species in the subtropics or tropics are usually timed to coincide with the peaks in insect activity, which is usually the wet season, but some species like the White-throated Blue Swallow

 sharing the duties equally and the female doing most of the work in others. Amongst the Barn Swallows the male of the American subspecies helps (to a small extent) whereas the European subspecies does not. Even in species where the male does not incubate the eggs the male may sit on them when the female is away to reduce heat loss. Incubation stints last for 5–15 minutes and are followed by bursts of feeding activity. From laying, swallow eggs take between 10–21 days to hatch, with 14–18 days being more typical.

The chicks of swallows hatch naked, generally with only a few tufts of down. The eyes are closed and do not fully open for up to 10 days. The feathers take a few days to begin to sprout, and the chicks are brooded by the parents until they are able to thermoregulate. On the whole they develop slowly compared to other passerine birds. The parents do not usually feed the chicks individual insects but instead a bolus of food comprising ten to a hundred insects. Regardless of whether the species has males that incubate or brood the chicks the males of all swallows and martins will help feed the chicks. It is difficult to judge when swallows and martins fledge

, as they will be enticed out of the nest after three weeks by parents but frequently return to the nest afterwards in order to roost.

Calls

Swallows are able to produce many different calls or songs, which are used to express excitement, to communicate with others of the same species, during courtship, or as an alarm when a predator is in the area. The songs of males are related to the body condition of the bird and are presumably used by females to judge the physical condition and suitability for mating of males. Begging calls are used by the young when soliciting food from their parents. The typical song of swallows is a simple, sometimes musical twittering.

Within the family there is a clear division between the two subfamilies, the Pseudochelidoninae which is composed of the two species of river martins, and the Hirundininae, into which the remaining 81 species are placed. The division of the Hirundininae has been the source of much discussion, with various taxonomists variously splitting them into as many as 24 genera and lumping them into just 12. There is some agreement that there are three core groups within then Hirundininae, the saw-wings of the genus Psalidoprocne
Psalidoprocne
The saw-wings, Psalidoprocne, is a small genus of passerine birds in the swallow family. The common name of this group is derived from the rough outer edge of the outer primary feather on the wing, which is rough due to recurved barbs. The function of this is unknown. The birds are 11–17 cm...
