The grey heron (Ardea cinerea) is a long-legged predatory wading bird of the heron family, Ardeidae, native throughout temperate Europe and Asia and also parts of Africa. It is resident in much of its range, but some populations from the more northern parts migrate southwards in autumn.

The purple heron (Ardea purpurea) is a wide ranging species of wading bird in the heron family, Ardeidae. The scientific name comes from Latin ardea "heron", and purpureus, "coloured purple". It breeds in Africa, central and southern Europe, and southern and eastern Asia.

The bearded vulture (Gypaetus barbatus), also known as the lammergeier or ossifrage, is a bird of prey and the only member of the genus Gypaetus. The bearded vulture is the only known animal whose diet is almost exclusively bone. The bearded vulture is found in mountainous regions from Europe through much of Asia and Africa.
