Swallow

Swallow

Swallows are small birds with dark, glossy-blue backs, red throats, pale underparts and long tail streamers. They are extremely agile in flight and spend most of their time on the wing. They are widespread breeding birds in the Northern Hemisphere, migrating south in winter.The swallows have a cospolotion description across the world and breed on all the continents except Antarctica. It is believed that this family originated in Africa as hole-nesters; Africa still has the greatest diversity of species. They also occur on a number of oceanic islands. A number of European and North American species are long-distance migrants; by contrast, the West and South African swallows are non-migratory. A few species of swallow and martin are threatened.
