Barn swallow
The swallow arrives in the UK in March and leaves again in October for its southern African wintering grounds. It is a slender bird with glossy blue-black upperparts and cream underparts with a black breast brand. The forehead and throat are red, and it has a deeply forked tail with a row of white spots and long streamers.
Swallows are most often seen in flight. Look out for them near villages, freshwater, and coasts, flying low over fields and water with their wings swept and tail spread, or gathered in groups on telegraph wires and other high points. It has a sharp call and a rapid, twittering, musical song.
Swallows build their nests tucked under the eaves of outbuildings, or under bridges and culverts. They have up to 3 broods a season and juveniles can be seen from late May.
