Swallows & Martins (Hirundinidae)
These are highly aerial birds that catch all their food on the wing, and are among the most masterful of all fliers. Several species undertake huge migrations from one end of the earth to the other. They are small birds with long, pointed wings and square-cut or forked tails. Their feet and legs are short and weak, and are used only for perching. They are highly gregarious.
There are eighty species worldwide, of which five breed in Europe.
