Coot birds.Coots have prominent frontal shields or other decoration on the forehead, with red to dark red eyes and coloured bills. Many, but not all, have white on the under tail. The featherless shield gave rise to the expression "as bald as a coot," which the Oxford English Dictionary cites in use as early as 1430. Like other rails, they have long, lobed toes that are well adapted to soft, uneven surfaces. Coots have strong legs and can walk and run vigorously. They tend to have short, rounded wings and are weak fliers, though northern species nevertheless can cover long distances.

The common murre or common guillemot (Uria aalge) is a large auk. It is also known as the thin-billed murre in North America. It has a circumpolar distribution, occurring in low-Arctic and boreal waters in the North Atlantic and North Pacific. It spends most of its time at sea, only coming to land to breed on rocky cliff shores or islands.

Common murres have fast direct flight but are not very agile. They are more manoeuvrable underwater, typically diving to depths of 30–60 m (98–197 ft). Depths of up to 180 m (590 ft) have been recorded.

Common murres breed in colonies at high densities. Nesting pairs may be in bodily contact with their neighbours. They make no nest; their single egg is incubated on a bare rock ledge on a cliff face. Eggs hatch after ~30 days incubation. The chick is born downy and can regulate its body temperature after 10 days. Some 20 days after hatching the chick leaves its nesting ledge and heads for the sea, unable to fly, but gliding for some distance with fluttering wings, accompanied by its male parent. Chicks are capable of diving as soon as they hit the water. The female stays at the nest site for some 14 days after the chick has left.

Both male and female common murres moult after breeding and become flightless for 1–2 months. In southern populations they occasionally return to the nest site throughout the winter. Northern populations spend the winter farther from their colonies.

A lumma madár Az északi félteke óceánjaiban a partok és szigetek sziklafalain fészkel, találkozhatunk vele Kanada, Alaszka, Grönland, Észak-Európa és Oroszország sziklás partjai körül is. Az Európában költő populáció 500 000 párból áll, ezekből 1000 Helgolandban (Németország) költ.Az ivarérettséget ötéves korban érik el. A költési időszak április-július között van. Évente egyszer költ. Egy fészekaljban egyetlen fehér tojás van, amely csúcsban végződik. Ez a forma biztosítja, hogy a tojás ne essen le a sziklák kiszögelléseiről. A tojáson mindkét szülő felváltva kotlik 30-35 napig. A fiatal madarak 18-24 nap után hagyják el a fészket, ekkor még nem is tudnak repülni, de azért a nyílt tengerre vezeti őket a hím.

Black swan (Cygnus atratus) is a large waterbird, a species of swan which breeds mainly in the southeast and southwest regions of Australia. A New Zealand subspecies was apparently hunted to extinction by Māori, but the species was reintroduced to New Zealand in the 1860s.[2] Within Australia they are nomadic, with erratic migration patterns dependent upon climatic conditions. Black swans are large birds with mostly black plumage and red bills. They are monogamous breeders, and are unusual in that one-quarter of all pairings are homosexual, mostly between males. Both partners share incubation and cygnet rearing duties.

Black swans were introduced to various countries as an ornamental bird in the 1800s, but have escaped and formed stable populations. A small population of black swans exists on the River Thames at Marlow, on the Brook running through the small town of Dawlish in Devon (they have become the symbol of the town) and near the River Itchen, Hampshire, there is also one on the River Tees near Stockton on Tees.

Fekete hattyú Nem vándorló faj, Délnyugat-Ausztráliában és Tasmaniában él. Nyugat-Ausztrália állam nemzeti madara.

A 19. század során betelepítették Új-Zélandra. Ott nagyon elszaporodott, ottani állományát 60 000 madárra becsülik. Mint kedvelt parkmadár, félvadon sok helyen él Európa parkjaiban is, de itt nem vadul ki, önfenntartó állományai vadon sehol nincsenek.

A vizes élőhelyeket részesíti előnyben, védett tengeröblökben és lagúnákban is előfordul.
