Palaearctic

Since the 1500s, only two bird species in the Western Palaearctic, a vast area spanning North Africa to polar regions, were considered to have gone extinct.

Incidentally, the different osprey subspecies/species do hybridise in some places and there are reasons for thinking that eastern Palaearctic and North American ospreys have become more alike – due to hybridisation – since the end of the Pleistocene.

Evidence for a second western Palaearctic seabird extinction during the last Millennium: the Lava shearwater Puffinus olsoni.

The fishes found in the rivers of the Himalaya show the same general connexion with the three neighbouring regions, the Palaearctic, the African and the Malayan.
