Grey Heron

The patient spear-fisher — a grey sentinel that stands motionless for minutes, then strikes like lightning.

Least Concern

Grey Heron

Overview

The grey heron is Britain's largest common heron — tall, slow, and statuesque at the edge of any pond, river, or park lake. It looks almost prehistoric: slate-grey plumage, a dagger bill, and a habit of standing utterly still until the moment it lunges at a fish.

Herons are familiar enough to be a reliable common, but never boring. Watch one for five minutes and you'll understand why — the stillness, the sudden strike, the awkward flap away if disturbed. They're on every canal and every village pond.

Habitat

Grey herons are found throughout the United Kingdom on rivers, lakes, ponds, estuaries, and park water. They nest in colonies called heronries — often in tall trees — and hunt alone at the water's edge in shallow water or on grassy banks.
