Hirundo
rustica
Swallows are an attractive species with a glossy blue/black upper body and
white underparts. They have distinctive red faces and throats plus long tail
'streamers' - male streamers are longer.
4-5 red spotted white eggs.
Size
17 - 19cm
Weight
16 - 25g
Habitat
Mixed farmland, often near cattle.

Usually on shelves or beams in buildings such as barns.
Eggs
4-5 red spotted white eggs.
Food
Flies, bees, butterflies and moths.
Voice
Sweet twittering song, a 'swit, swit, swit' call.
Characteristics
A graceful and elegant bird often seen swooping over water looking for
insects, the Swallow arrives in the UK in March after a winter in Africa. Before
migrating back to Africa huge flocks will gather together on telegraph
wires.
BTO Statistics
Swallows are amber-listed as they have suffered moderate declines in recent
years. The Swallow's vulnerability is thought to relate to a reduction in insect
populations - their main source of food - and a shortage of suitable nesting
sites.
Breeding
Nests are cup or half-cup shaped and built with a lot of mud. The incubation
period lasts for 14-15 days, fledglings leave the nest 19-21 days after
hatching. They are still fed by their parents for another week. Parents are very
protective of their young and will mob any predators including cats and magpies
and drive them away from the nest.
Feeding
Swallows eat and drink on the wing. However, if there is a shortage of flying
insects they will take small invertebrates from the ground.
