Water Birds: Herons, Ducks, Waders and Divers of Lakes, Rivers and Coasts

A guide to 18 recognisable water birds — herons, egrets, ducks, geese, swans, kingfishers, flamingos, pelicans, cormorants, grebes, ibises, storks, cranes…

At a glance

Water birds are not one scientific family: the name covers unrelated birds that feed, swim or wade in wetlands, from metre-tall herons to the palm-sized kingfisher. This guide focuses on identification and responsible observation — what each bird looks like, where it lives and how it feeds — using well-established natural-history references.

Grey heron — Tall grey wader that hunts by standing still at the water's edge
Great egret — Tall all-white heron of shallow wetlands worldwide

The brands in detail

Grey heron

The grey heron is one of the most familiar large wading birds of the Old World, standing about a metre tall with grey upperparts, a white head and neck, a black eyebrow stripe that extends into wispy plumes, and a dagger-like yellow bill. It waits motionless at the edge of lakes, rivers, marshes and even garden ponds, then strikes with a sudden jab of the neck to catch fish, frogs and other small animals. In flight the neck folds back into an S-shape and the broad wings beat slowly, which separates herons from storks and cranes. Grey herons usually nest colonially in tall trees in heronries, building large stick nests, and they are widespread across Europe, Asia and parts of Africa, with northern birds moving south in hard winters.

Great egret

The great egret is a tall, all-white heron found on every continent except Antarctica, easily recognised by its size, long black legs, and yellow bill that turns partly dark in the breeding season, when delicate lacy plumes trail from its back. Those plumes were once so prized for fashion that the species was hunted close to collapse in some regions, and protecting it helped inspire early bird-protection societies. It stalks slowly through shallow wetlands, flooded fields and mangroves, spearing fish, frogs, crustaceans and insects with quick thrusts of the bill. Great egrets often nest in colonies alongside other herons and egrets, building stick platforms in trees or reedbeds over water, and they have expanded their range noticeably during the last century.

Mallard

The mallard is the world's most familiar duck and the ancestor of nearly all domestic ducks. The drake is unmistakable in breeding plumage, with a glossy green head, white collar, chestnut breast and a grey body ending in curled black tail feathers, while the female is mottled brown with an orange-and-brown bill; both sexes show a blue-purple speculum edged with white on the wing. Mallards are dabbling ducks: they feed at the surface or tip tail-up to reach aquatic plants, seeds, snails and insects in ponds, marshes, rivers and city parks, and they rarely dive. Highly adaptable and largely resident where water stays unfrozen, they breed across the Northern Hemisphere, nesting on the ground near water, and females raise the striped ducklings alone.

Greylag goose

The greylag goose is the bulky ancestor of most domestic farmyard geese and the largest of the grey geese native to Europe and Asia. It is brownish-grey overall with a heavy orange-pink bill, pink legs, lighter fringes to the back feathers and a pale belly often marked with dark flecks. Greylags graze on grass, roots and cereal stubble, usually in family parties that stay together through the winter, and they are strong, vocal fliers that travel in noisy skeins between wetlands and feeding fields. Northern populations breed beside lakes and marshes in Iceland, Scandinavia and across northern Asia and migrate south for winter, while many southern birds are resident; reintroduced and feral flocks now breed widely in parks and gravel pits.

Mute swan

The mute swan is a huge, graceful white waterbird of lakes, slow rivers and coastal lagoons across Europe and Asia, widely introduced elsewhere including North America. Adults are identified by the orange bill with a prominent black knob at its base, and they often swim with the neck curved into a gentle S and wings slightly raised. Despite the name they are not silent: they hiss, snort and grunt, and their wings make a throbbing hum in flight. Mute swans feed mainly on underwater plants reached with the long neck, and pairs defend a territory fiercely while raising grey-brown cygnets on a large mound nest at the water's edge; long-term pair bonds are typical.

Common kingfisher

The common kingfisher is a small, jewel-bright bird of rivers, streams, canals and lakeshores across Europe, Asia and North Africa: electric blue-green above, rich orange below, with a long black dagger bill — females show an orange-red tint on the lower bill. It hunts from a low perch over clear, slow water, watching for small fish, then plunges headfirst and returns to beat its catch on the branch before swallowing it head-first. Kingfishers fly fast and low over the water with whirring wings and a piercing whistle. They nest in a tunnel dug into a steep earth bank, and because they need clear water and plentiful small fish, their presence is often taken as a sign of a healthy waterway.

Greater flamingo

The greater flamingo is the largest and palest of the flamingos, a tall pink wader of shallow lagoons, salt pans, estuaries and alkaline lakes around the Mediterranean, Africa and southern Asia. Its oddly bent bill — pink with a black tip — is held upside down in the water while the bird shuffles forward, filtering out algae, diatoms, tiny crustaceans and insect larvae with comb-like plates; the pink colour itself comes from carotenoid pigments in that food. Greater flamingos are intensely social, feeding and displaying in groups that can number thousands, and they breed colonially on mud mounds in the shallows, where both parents feed the chick on a milk-like secretion. In flight, neck and legs stretch out in a line and the black flight feathers flash against the pink wings.

Great white pelican

The great white pelican is one of the largest flying birds in the world, with a wingspan that can exceed three metres, brilliant white plumage, black flight feathers and an enormous orange-yellow bill with a stretchy throat pouch. It breeds in colonies around shallow lakes, deltas and marshes in south-eastern Europe, Asia and Africa, laying its eggs in a scrape on the ground. Unlike the brown pelican, it never plunge-dives: groups fish cooperatively at the surface, herding fish into the shallows and scooping them up in their pouches. Great white pelicans are superb soaring birds that ride thermals in long lines between feeding and breeding waters, and northern populations migrate long distances to warmer wintering grounds.

Great cormorant

The great cormorant is a large, dark fishing bird found on coasts and inland waters almost worldwide. Adults are blackish with a green-bronze sheen, a white throat patch and, in breeding dress, white patches on the head and thigh; the hooked bill and fully webbed feet mark it as a pursuit diver. Cormorants swim low in the water, dive from the surface and chase fish underwater, sometimes working in groups, then return to a post, rock or dead tree and stand with wings held half-open — a posture thought to help dry feathers that are less waterproof than those of most waterbirds. They nest colonially in trees, cliffs or on the ground, and inland populations have increased greatly in recent decades, which sometimes brings them into conflict with fisheries.

Great crested grebe

The great crested grebe is an elegant diving bird of lakes, reservoirs and slow rivers across Europe, Asia, Africa and Australasia, famous for its elaborate courtship: pairs face each other, shake their heads, dive and rise together, and perform a dance in which both birds rear up chest-to-chest offering beakfuls of weed. In breeding plumage it has chestnut cheek frills and black double crest tufts; in winter it is plainer grey and white. Grebes are almost entirely aquatic — their legs are set so far back that they can barely walk — and they dive to catch fish and aquatic invertebrates, building a floating nest of weed anchored to reeds. Chicks are striped and often ride on a parent's back among the feathers.

Glossy ibis

The glossy ibis is a slim, dark wading bird of marshes, rice fields, flooded meadows and estuaries, with a long, downcurved bill for probing soft mud. At a distance it looks blackish, but in good light the plumage shines chestnut, green and purple — the glossy finish that gives it its name. It feeds in small flocks, walking slowly through shallow water and feeling for insect larvae, snails, crustaceans, frogs and small fish. The glossy ibis is the most widespread ibis in the world, breeding in scattered colonies, often alongside herons and spoonbills, across southern Europe, Asia, Africa, Australia and the Americas, and its range has expanded in recent decades; northern breeders move south after the breeding season.

White stork

The white stork is a large, much-loved bird of open farmland, wet meadows and marshes across Europe, Africa and western Asia, white with black flight feathers, a long red bill and long red legs. It is famous for nesting on rooftops, chimneys, pylons and specially built platforms in villages and towns, building huge stick nests that pairs reuse and add to year after year, and for greeting its mate by throwing back its head and clattering its bill. White storks walk steadily through grassland and shallows hunting frogs, large insects, earthworms and small mammals. European birds migrate in vast soaring flocks, western birds crossing at Gibraltar and eastern birds via the Bosphorus to winter in Africa, avoiding long sea crossings by riding thermals over land.

Common crane

The common crane is a tall, stately grey bird of wetlands and farmland across northern Europe and Asia, with a black-and-white head pattern, a splash of red on the crown and a bustle of drooping inner wing feathers over the tail. Its far-carrying, trumpeting calls are among the classic sounds of wild wetlands. Cranes feed in flocks on plant material, grain, insects and small animals in shallow marshes, bogs and stubble fields, and pairs perform leaping, bowing dances with raised wings, most often in spring. They breed in undisturbed wetlands, building a mound of reeds in shallow water, and migrate in family groups along traditional routes to wintering grounds in southern Europe, Africa and southern Asia, with major staging sites where thousands gather.

European herring gull

The European herring gull is the archetypal large gull of northern coasts, harbours and seaside towns: pale grey above, white below, with black wingtips spotted white, pink legs and a strong yellow bill carrying a red spot on the lower mandible, which chicks peck to prompt feeding. It is an opportunistic omnivore, eating fish, crabs, shellfish — sometimes dropped onto rocks to break them open — eggs, refuse and scavenged scraps, and it is quick to exploit fishing boats and harbours. Herring gulls nest colonially on cliffs, islands, beaches and increasingly on flat rooftops, defending noisy territories while raising speckled chicks. Young birds take four years to reach adult plumage, passing through mottled brown stages that make gull identification a famous challenge.

Common tern

The common tern is a slim, graceful seabird of coasts, lakes and rivers across the Northern Hemisphere, silvery grey and white with a black cap, deeply forked tail and a red bill usually tipped with black. It hunts by hovering over the water and plunge-diving for small fish and crustaceans, often in loose, noisy flocks. Common terns breed in colonies on beaches, shingle banks, islands and even flat roofs or rafts, laying camouflaged eggs in a simple scrape and mobbing intruders boldly. They are champion migrants: birds breeding in northern Europe and North America winter off Africa and South America, and the species' close relative the Arctic tern outdoes even that. Adults take several years to breed and can live for decades.

Eurasian coot

The Eurasian coot is a stocky, soot-black waterbird of lakes, ponds, marshes and slow rivers across Europe, Asia, Africa and Australia, instantly recognised by its white bill that runs up into a white shield on the forehead — the origin of the phrase 'bald as a coot'. Its toes are lobed rather than fully webbed, an adaptation that suits both swimming and walking on floating vegetation. Coots graze on aquatic plants, algae, seeds and invertebrates, diving or upending to reach them, and they are famously quarrelsome, charging at rivals with splashing runs across the surface. Pairs build a bulky nest of reeds at the water's edge and raise black chicks with startling orange-red down on the head; adults outside breeding areas gather in large winter rafts.

Common moorhen

The common moorhen is a familiar, medium-sized waterbird of ponds, ditches, marshes and park lakes on every continent except Antarctica and Australia. Adults are dark slate-grey and brown with a white stripe along the flank, white undertail patches flashed as the bird flicks its tail, and a striking red bill with a yellow tip that extends into a red forehead shield. Moorhens swim with a jerky, nodding motion and walk delicately over lily pads and mud on long greenish legs with very long toes that spread their weight. They feed on water plants, seeds, snails, insects and other small creatures, and build a nest of reeds hidden in waterside vegetation; earlier broods sometimes stay on to help feed later chicks.

Osprey

The osprey is a fish-eating hawk found on every continent except Antarctica, dark brown above and white below, with a white head crossed by a dark eye-stripe and long, narrow wings that show a distinctive crook at the wrist when soaring. It hunts over lakes, rivers, reservoirs and coasts, hovering or circling before folding its wings and plunging feet-first into the water — its reversible outer toe and spiny foot pads help it grip slippery fish, which it turns head-first into the wind as it flies to a perch or nest. Ospreys build large stick nests on dead trees, cliffs, channel markers and purpose-built platforms, often reusing them for years. Northern populations migrate thousands of kilometres to winter in Africa, South America and southern Asia.
