Our planet has a bounty of birds—greater than 11,000 species in all. However on a world scale, most have comparatively small ranges. And only some dozen species will be referred to as “cosmopolitan,” with ranges that contact six continents or at the very least three oceans. These are the birds that tie our human world collectively—birds that just about all of us have in frequent.
The Barn Swallow on the high of this web page is without doubt one of the greatest examples: a chook weighing lower than an oz., whose migratory routes contact Canada, Tierra del Fuego, Norway, Namibia, Russia, Australia, and most locations in between. Their gleaming colours and swish aerobatics delight birdwatchers on each continent save Antarctica.
Comply with us on a tour of our favourite cosmopolitan birds—whether or not over land, in cities and cities, or out at sea.
