# Grey Heron (*Ardea cinerea*)

> The grey heron (Ardea cinerea) is a tall, long-legged wading bird found in wetlands, rivers, and coasts across Eurasia and Africa. Standing up to a metre tall with grey, white, and black plumage, it hunts by standing motionless before spearing fish, amphibians, and small mammals with its dagger-like bill. A patient and adaptable predator, it can live up to 25 years and is listed as Least Concern.

## Patient hunting technique

The grey heron is the archetypal ambush hunter, standing frozen at the water's edge for long stretches before striking with astonishing speed. When a fish or frog moves within reach, the bird uncoils its S-shaped neck and spears or seizes the prey with its long, sharp bill. Fish form the bulk of its diet, but it also takes amphibians, small mammals, insects, and even ducklings. This patient, energy-efficient style lets it hunt successfully in almost any shallow water.

## Appearance and flight

Grey herons are unmistakable, with pale grey upperparts, a white head and neck marked by a black eye-stripe and crest, and a long yellowish bill. In flight they fold the neck back into a distinctive S-shape and trail their long legs behind, beating broad wings slowly and steadily at up to 40 km/h (25 mph). Standing nearly a metre tall, they are among the largest and most familiar wetland birds of Europe. Their unhurried, deliberate movements make them easy to recognise even at a distance.

## Wetland habitat

The grey heron occupies almost any body of water with fish, from rivers, lakes, and marshes to estuaries, coastlines, and even garden ponds. This adaptability has allowed it to thrive across a vast range spanning Eurasia and Africa. In many towns and cities it has become a bold and familiar sight, patrolling park lakes and raiding ornamental fish ponds. It needs only shallow water for hunting and nearby trees or reedbeds for roosting and nesting.

## Nesting in colonies

Grey herons breed in colonies known as heronries, typically building large stick nests high in tall trees. The same sites are used year after year and may hold dozens of nests, making a noisy, conspicuous spectacle in early spring. The female usually lays three to five pale blue eggs, and both parents share incubation and feeding of the growing chicks. Young herons fledge after around seven to eight weeks but often return to be fed for a time afterwards.

## Behaviour and lifespan

Outside the breeding season grey herons are largely solitary, defending favoured fishing spots and often standing hunched and motionless for hours. They are long-lived for a bird of their size, surviving 15 to 25 years in the wild, though many young birds do not make it through their first hard winter. Cold spells that freeze their hunting waters are one of the main causes of death. Their patience and adaptability otherwise make them resilient survivors.

## Range and status

The grey heron is widespread and common throughout its enormous range across Europe, Asia, and Africa, and the IUCN lists it as Least Concern. Legal protection in many countries and its ease with human-altered habitats have helped keep populations healthy. It is one of the most familiar large birds of British and European waterways. Numbers can dip after severe winters but generally recover quickly.

## Frequently asked questions

### What do grey herons eat?

Grey herons eat mainly fish, which they catch by standing still and spearing prey with their sharp bill. They also take amphibians, small mammals, insects, and occasionally ducklings and other small birds.

### How tall is a grey heron?

A grey heron stands up to about a metre (roughly 3 feet) tall, making it one of the largest wetland birds in Europe. Despite its size it weighs only 1 to 2 kg, as birds have lightweight bones.

### Why do herons stand so still?

Herons stand motionless to ambush prey without alarming it. By waiting patiently at the water's edge, they can strike the instant a fish or frog comes within reach of their long neck and bill.

### Do herons nest together?

Yes, grey herons nest in colonies called heronries, usually high in tall trees. The same sites are reused each year and can hold dozens of large stick nests.

### How long do grey herons live?

Grey herons can live 15 to 25 years in the wild, which is long for a bird of their size. Many young birds, however, die during their first winter if freezing weather locks up their fishing waters.

### Are grey herons a threat to garden ponds?

They can be, as herons readily raid ornamental ponds for fish. Pond netting, cover, and hiding places for fish are the usual ways to deter them without harming the bird.
