List of birds of Europe
More than 900 species of birds have been observed in Europe. The avifauna of Europe is broadly similar to that of Asia north of the Himalayas and North Africa, both of which also belong to the Palearctic realm. There are also many groups shared with North America. On the other hand, many groups characteristic of the Afrotropical and Indomalayan realms are entirely absent from Europe, including jacanas, darters, trogons, hornbills, honeyguides, barbets (families Lybiidae in Africa and Megalaimidae in Asia), parrots, pittas, cuckooshrikes, broadbills (families Calyptomenidae and Eurylaimidae), drongos, monarch flycatchers, white-eyes, and estrildid finches (although parrots and estrildid finches have been introduced to Europe by humans). Two species that occurred in the European region until recently (post 1800) — the great auk and the Canary Islands oystercatcher — are now globally extinct, while one additional species — the slender-billed curlew — may also be extinct.
