The ibis are a group of long-legged wading birds in the family Threskiornithidae that inhabit wetlands, forests and plains. "Ibis" derives from the Latin and Ancient Greek word for this group of birds. It also occurs in the scientific name of the western cattle egret mistakenly identified in 1757 as being the sacred ibis.
Spoonbills are a genus, Platalea, of large, long-legged wading birds. The spoonbills have a global distribution, being found on every continent except Antarctica. The genus name Platalea derives from Ancient Greek and means "broad", referring to the distinctive shape of the bill. Six species are recognised, which although usually placed in a single genus have sometimes been split into three genera.
The family Threskiornithidae includes 36 species of large wading birds. The family has been traditionally classified into two subfamilies, the ibises and the spoonbills; however recent genetic studies have cast doubt on this arrangement, and have found the spoonbills to be nested within the Old World ibises, and the New World ibises as an early offshoot.
The American white ibis is a species of bird in the ibis family, Threskiornithidae. It is found from the southern half of the US East Coast, along the Gulf Coast states and south through most of the Caribbean coastal regions of Central America. This particular ibis species is a medium-sized wading bird, possessing an overall white plumage with black wing-tips, and having the typical downward-curving bill of the ibises, though of a bright red-orange color, the same hue as its long legs. Males are larger and have longer bills than females. The breeding range runs along the Gulf and Atlantic Coast, and the coasts of Mexico and Central America. Outside the breeding period, the range extends further inland in North America and also includes the Caribbean. It is also found along the northwestern South American coastline in Colombia and Venezuela. Populations in central Venezuela overlap and interbreed with the scarlet ibis. The two have been classified by some authorities as a single species.
The scarlet ibis, sometimes called red ibis, is a species of ibis in the bird family Threskiornithidae. It inhabits tropical South America and part of the Caribbean. In form, it resembles most of the other twenty-seven extant species of ibis, but its remarkably brilliant scarlet coloration makes it unmistakable. It is one of the two national birds of Trinidad and Tobago, and its Tupi–Guarani name, guará, is part of the name of several municipalities along the coast of Brazil.
The white-faced ibis is a wading bird in the ibis family, Threskiornithidae.
The Eurasian spoonbill, or common spoonbill, is a wading bird of the ibis and spoonbill family Threskiornithidae. The genus name Platalea is from Latin and means "broad", referring to the distinctive shape of the bill, and leucorodia is from Ancient Greek leukerodios "spoonbill", itself derived from leukos, "white" and erodios "heron". In England it was traditionally known as the "shovelard", a name later used for the northern shoveler.
The roseate spoonbill is a gregarious wading bird of the ibis and spoonbill family, Threskiornithidae. It is a resident breeder in both South and North America. The roseate spoonbill's pink color is diet-derived, consisting of the carotenoid pigment canthaxanthin, like the American flamingo.
The black-faced spoonbill is a species of wading bird in the ibis and spoonbill family Threskiornithidae, found in eastern Asia. This species has the most restricted distribution of the six spoonbill species, and it is the only one regarded as endangered. Spoonbills are large water birds with dorso-ventrally flattened, spatulate bills. These birds use a tactile method of feeding, wading in the water and sweeping their beaks from side-to-side to detect prey. Confined to the coastal areas of eastern Asia, it seems that it was once common throughout its area of distribution. It currently breeds only on a few small rocky islands off the west coast of North Korea, with four wintering sites at Macau, Hong Kong, Taiwan and Vietnam, as well as other places where they have been observed in migration. Wintering also occurs in Jeju, South Korea, Kyushu and Okinawa, Japan, and the Red River delta in Vietnam. More recently, sightings of black-faced spoonbill birds were noted in Thailand, the Philippines, and additional sites in China.
Gymnogyps is a genus of New World vultures in the family Cathartidae. There are five known species in the genus, with only one being extant, the California condor.
The small bird genus Geronticus belongs to the ibis subfamily Threskiornithinae. Its name is derived from the Greek gérontos in reference to the bald head of these dark-plumaged birds; in English, they are called bald ibises.
The royal spoonbill also known as the black-billed spoonbill, occurs in intertidal flats and shallows of fresh and saltwater wetlands in Australia, New Zealand, Indonesia, Papua New Guinea, and the Solomon Islands. It has also been recorded as a vagrant in New Caledonia. The royal spoonbill lives in wetlands and feeds on crustaceans, fish and small insects by sweeping its bill from side to side. It always flies with its head extended. Widespread throughout its large range, the royal spoonbill is evaluated as Least Concern on the IUCN Red List of Threatened Species.
The yellow-billed spoonbill is a gregarious wading bird of the ibis and spoonbill family, Threskiornithidae. It is native to Australia, and is a vagrant to New Zealand, Lord Howe Island and Norfolk Island.
The green ibis, also known as the Cayenne ibis, is a wading bird in the ibis family Threskiornithidae. It is the only member of the genus Mesembrinibis.
Ardea is a genus of herons. These herons are generally large in size, typically 80–100 cm or more in length.
The buff-necked ibis, also known as the white-throated ibis, is a fairly large ibis found widely in open habitats of eastern and northern South America. It formerly included the similar black-faced ibis as a subspecies, but that species is almost entirely restricted to colder parts of South America, has a buff lower chest, and lacks the contrasting large white wing-patches.
Plegadis is a bird genus in the family Threskiornithidae. The genus name derives from Ancient Greek plegados, "sickle", referring to the distinctive shape of the bill. Member species are found on every continent except Antarctica as well as a number of islands.
Theristicus is a genus of birds in the family Threskiornithidae. They are found in open, grassy habitats in South America. All have a long, decurved dark bill, relatively short reddish legs that do not extend beyond the tail in flight, and at least the back is grey.
The black-faced ibis is a species of bird in the family Threskiornithidae. It is found in grassland and fields in southern and western South America. It has been included as a subspecies of the similar buff-necked ibis, but today all major authorities accept the split. The black-faced ibis also includes the Andean ibis as a subspecies. Some taxonomic authorities still do so.
Gerandibis is an extinct genus of ibis known from fossil remains from early Miocene (Aquitanian) beds in France. It contains a single species, Gerandibis pagana, which was originally described by Milne-Edwards in 1868 as Ibis pagana. Richard Sharpe classified it in the genus Eudocimus, but Storrs L. Olson placed it in the genus Plegadis due to anatomical similarities closer to that genus. The ibises of the genus Plegadis have two natural foramina (holes) in the intertrochlear groove in the distal section of the tarsometatarsus, where as ibises of Eudocimus have one small foramen. P. paganus has two small holes akin to living species of Plegadis. The species was eventually made the type species of a separate genus Gerandibis by Vanesa L. De Pietri (2013).
