フクロウ
The mistle thrush is predated upon by a wide variety of birds of prey, including the boreal owl, short-eared owl, tawny owl, Ural owl, Eurasian eagle-owl, golden eagle, kestrel, common buzzard, red kite, northern goshawk, peregrine falcon, and sparrowhawk. The eggs and chicks may be targeted by cats and corvids. Parent birds exhibit fearlessness in defence of their nests, occasionally even attacking humans. The mistle thrush is not normally a host of the common cuckoo, a brood parasite.
