Barn Swallow
Scientific Name:
Hirundo rustica
Length:
17-21cm Description
Swallows are slimmer and more elegant than the Martins, a feature exaggerated by the long tail streamers of the adults. The dark throat and, of course, the all-dark rump separate them easily from House Martins and Red-rumped Swallows.
Distribution
Approx 570,000 territories in Britain with 250,000 in Ireland. A widespread bird over both islands.
Habitat
Breeds mostly in farm buildings. Feeds in the air usually over open country.
Diet
Insects.
Population
Britain has seen a steady decline during the 1980's. This could be due to pesticide usage which has greatly reduced the numbers of insects thier main food source . Higher mortality in their wintering areas could also be having an impact.
