The king rail (Rallus elegans) is a waterbird, the largest North American rail.
Distinct features are a long bill with a slight downward curve, with adults being brown on the back and rusty-brown on the face and breast with a dark brown cap. They also have a white throat and a light belly with barred flanks. Undertail coverts are white and are displayed by the male during courtship. [2] Immature birds are covered in down, [3] with light brown on the head and darker brown on the back and wings.
This bird's call is a low repeated grunt transcribed as kek-kek-kek. [4]

This bird breeds in marshes in eastern North America. Birds along the southeastern coasts of the United States are permanent residents. Other birds migrate to the southern United States and Mexico; in Canada, they are found in southern Ontario. An adult king rail will molt completely after nesting and it becomes flightless for almost a month. [7]
This bird is diurnal, contrasting with its smaller, nocturnal relatives. [3]
The nest is a raised platform built with marsh vegetation and covered by a canopy. This is to hide the eggs of this bird from predators that are searching from above. [3]
The king rail interbreeds with the clapper rail (Rallus crepitans) where their ranges overlap; It can be argued that these two birds belong to the same species according to the biological species concept.
The king rail lays a clutch of 6 to 14 pale buff eggs with brown spotting. They usually measure 41 by 30 millimetres (1.6 by 1.2 in). Both parents incubate the eggs for 21 to 23 days. When the eggs hatch, the young are covered in down and are able to leave the nest. They are not able to feed themselves, though, and thus must rely on their parents for food for up to six weeks after they hatch. [3]
This rail forages in shallow water near cover and eats mainly aquatic insects and crustaceans. It forages by probing the mud while moving around in shallow water. [3]
The chicks are fed small arthropod prey by their parents. The prey is transferred from one parent's beak to that of the chick. [3]
Males often give food to whomever they pursue during courtship. [2] [7]
These birds are still common in some coastal areas, although interior populations have declined due to habitat loss. [3] In Michigan, it is considered a legally protected state endangered species, at an imperiled level. [8]
The great blue heron is a large wading bird in the heron family Ardeidae, common near the shores of open water and in wetlands over most of North and Central America, as well as far northwestern South America, the Caribbean and the Galápagos Islands. It is occasionally found in the Azores and is a rare vagrant to Europe. An all-white population found in south Florida and the Florida Keys is known as the great white heron. Debate exists about whether these white birds are a color morph of the great blue heron, a subspecies of it, or an entirely separate species.
The black-necked grebe or eared grebe is a member of the grebe family of water birds. It was described in 1831 by Christian Ludwig Brehm. Its breeding plumage features distinctive ochre-coloured feathers which extend behind its eye and over its ear coverts. The rest of the upper parts, including the head, neck, and breast, are coloured black to blackish brown. The flanks are tawny rufous to maroon-chestnut, and the abdomen is white. In its non-breeding plumage, this bird has greyish-black upper parts, including the top of the head and a vertical stripe on the back of the neck. The flanks are also greyish-black. The rest of the body is a white or whitish colour. The juvenile has more brown in its darker areas. This species is present in parts of Africa, Eurasia, and the Americas.
The northern harrier, also known as the marsh hawk or ring-tailed hawk, is a bird of prey. It breeds throughout the northern parts of the northern hemisphere in Canada and the northernmost USA.
The limpkin, also called carrao, courlan, and crying bird, is a large wading bird related to rails and cranes, and the only extant species in the family Aramidae. It is found mostly in wetlands in warm parts of the Americas, from Florida to northern Argentina, but has been spotted as far north as Wisconsin and Southern Ontario. It feeds on molluscs, with the diet dominated by apple snails of the genus Pomacea. Its name derives from its seeming limp when it walks.
The snowy egret is a small white heron. The genus name comes from Provençal French for the little egret, aigrette, which is a diminutive of aigron, 'heron'. The species name thula is the Araucano term for the black-necked swan, applied to this species in error by Chilean naturalist Juan Ignacio Molina in 1782.
The sora, sora rail or Carolina crake is a small waterbird of the rail family Rallidae, sometimes also referred to as the sora rail or sora crake, that occurs throughout much of North America. The genus name Porzana is derived from Venetian terms for small rails, and the specific carolina refers to the Carolina Colony. The common name "Sora" is probably taken from a Native American language.
The Virginia rail is a small waterbird, of the family Rallidae. These birds remain fairly common despite continuing loss of habitat, but are secretive by nature and more often heard than seen. They are also considered a game species in some provinces and states, though rarely hunted. The Ecuadorian rail is often considered a subspecies, but some taxonomic authorities consider it distinct.
The water rail is a bird of the rail family which breeds in well-vegetated wetlands across Europe, Asia and North Africa. Northern and eastern populations are migratory, but this species is a permanent resident in the warmer parts of its breeding range. The adult is 23–28 cm (9–11 in) long, and, like other rails, has a body that is flattened laterally, allowing it easier passage through the reed beds it inhabits. It has mainly brown upperparts and blue-grey underparts, black barring on the flanks, long toes, a short tail and a long reddish bill. Immature birds are generally similar in appearance to the adults, but the blue-grey in the plumage is replaced by buff. The downy chicks are black, as with all rails. The former subspecies R. indicus, has distinctive markings and a call that is very different from the pig-like squeal of the western races, and is now usually split as a separate species, the brown-cheeked rail.
Brewer's blackbird is a medium-sized New World blackbird. It is named after the ornithologist Thomas Mayo Brewer.
Forster's tern is a tern in the family Laridae. The genus name Sterna is derived from Old English "stearn", "tern", and forsteri commemorates the naturalist Johann Reinhold Forster.
The Snares penguin, also known as the Snares crested penguin and the Snares Islands penguin, is a penguin from New Zealand. The species breeds on the Snares Islands, a group of islands off the southern coast of the South Island. It is a yellow-crested penguin, with a size of 50–70 cm (19.5–27.5 in) and a weight of 2.5–4 kg (5.5–8.8 lb). It has dark blue-black upper parts and white underparts. It has a bright yellow eyebrow-stripe which extends over the eye to form a drooping, bushy crest. It has bare pink skin at the base of its large red-brown bill.
The black-legged kittiwake is a seabird species in the gull family Laridae. This species was first described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae as Larus tridactylus. The English name is derived from its call, a shrill 'kittee-wa-aaake, kitte-wa-aaake'. In North America, this species is known as the black-legged kittiwake to differentiate it from the red-legged kittiwake, but in Europe, where it is the only member of the genus, it is often known just as kittiwake.
The black rail is a mouse-sized member of the rail family Rallidae that occurs in both North and South America.
Ridgway's rail is a species of bird found principally along the Pacific coast of North America from the San Francisco Bay Area to southern Baja California, as well as in some regions of the Gulf of California. A member of the rail family, Rallidae, it is a chicken-sized bird that lives brackish tidal marshes and rarely flies. Its name commemorates American ornithologist Robert Ridgway.
The brown noddy or common noddy is a seabird in the family Laridae. The largest of the noddies, it can be told from the closely related black noddy by its larger size and plumage, which is dark brown rather than black. The brown noddy is a tropical seabird with a worldwide distribution, ranging from Hawaii to the Tuamotu Archipelago and Australia in the Pacific Ocean, from the Red Sea to the Seychelles and Australia in the Indian Ocean and in the Caribbean to Tristan da Cunha in the Atlantic Ocean. The brown noddy is colonial, usually nesting on elevated situations on cliffs or in short trees or shrubs. It only occasionally nests on the ground. A single egg is laid by the female of a pair each breeding season. In India, the brown noddy is protected in the PM Sayeed Marine Birds Conservation Reserve.
The black crake is a waterbird in the rail and crake family, Rallidae. It breeds in most of sub-Saharan Africa except in very arid areas. It undertakes some seasonal movements in those parts of its range which are subject to drought. No subspecies have been described. It appears that the oldest available name for this species is actually Rallus niger J. F. Gmelin, 1788, but Swainson believed that the earlier name was unidentifiable, and his own has since become well embedded in the literature.
The maguari stork is a large species of stork that inhabits seasonal wetlands over much of South America, and is very similar in appearance to the white stork; albeit slightly larger. It is the only species of its genus to occur in the New World and is one of the only three New World stork species, together with the wood stork and the jabiru.
The Bogotá rail is a Vulnerable species of bird in subfamily Rallinae of family Rallidae, the rails, gallinules, and coots. It is endemic to Colombia. The bird is a typical medium-sized rail with a plump body that is laterally compressed, a short tail and an elongated bill.
The plain-flanked rail is an Endangered species of bird in subfamily Rallinae of family Rallidae, the rails, gallinules, and coots. It is endemic to Venezuela.
The mangrove rail is a species of bird in subfamily Rallinae of family Rallidae, the rails, gallinules, and coots. It is found in Central and South America.
