Ardea purpurea (*)
Ardea purpurea Linnaeus, 1766
Systema Naturae ed.12 p.236
The Purple Heron (Ardea purpurea) is a wading bird in the heron family Ardeidae, breeding in Africa, central and southern Europe, and southern and eastern Asia. The European populations are migratory, wintering in tropical Africa; the more northerly Asian populations also migrate further south within Asia. It is a rare but regular wanderer north of its breeding range.
The Purple Heron is a large bird, 80-90 cm tall, with a 120-150 cm wingspan, but slender for its size, weighing only 0.5-1.3 kg. It is somewhat smaller than the Grey Heron, from which it can be distinguished by its darker reddish-brown plumage, and, in adults, darker grey back. It has a narrower yellow bill, which is brighter in breeding adults.
There are three or four subspecies:
* Ardea purpurea purpurea Linnaeus, 1766. Africa, Europe north to the Netherlands, and southwestern Asia east to Kazakhstan.
The Purple Heron breeds in colonies in reed beds or trees close to large lakes or other extensive wetlands. It builds a bulky stick nest.
It feeds in shallow water, spearing fish, frogs, insects, small mammals, reptiles and small birds. It will often wait motionless for prey, or slowly stalk its victim. It tends to keep within reedbeds more than the Grey Heron, and is often inconspicuous, despite its size.
The Purple Heron is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies.
