The grey heron (lat. Ardea cinerea) is a long-legged bird of the heron family - the largest and most common European heron that lives, breeds, and moves across Europe, Asia, and Africa. In Greece, the gray heron is an epidemic bird that nests in the wetlands of Northern Greece, where it migrates from Central and Northern Europe to winter.
It occurs in coastal wetlands, and shallow waters (fresh, brackish, or salty), both stagnant and flowing, while in general, it prefers areas with trees, since it perches or nests on them. It also inhabits deltas and estuaries.
With its gray plumage and the black plume on its head, the gray-black stripes on the chest, and its long-hanging wings, the gray egret is easily distinguished from the rest of the herons. Its grey-yellow and dagger-shaped beak is also characteristic.
