Swallow

                The swallows are a group of passerine birds in the family Hirundinidae which are characterised by their adaptation to aerial feeding. The swallows have a cosmopolitan distribution across the world and breed on all the continents except Antarctica. 
                Hirundinidae are divided in: Psalidoprocne, Pseudhirundo, Cheramoeca, Phedina, Riparia, Tachycineta, Progne, Notiochelidon, Haplochelidon, Atticora, Neochelidon, Stelgidopteryx, Alopochelidon, Hirundo, Ptyonoprogne, Delichon, Cecropis, Petrochelidon. The most common species are tree swallow and barn swallow. Swallows are tolerated by humans because of their beneficial role as insect-eaters, and some species have readily adapted to nesting in and around human habitation.
