The openbill storks or openbills are two species of stork (family Ciconiidae) in the genus Anastomus. They are large wading birds characterized by large bills, the mandibles of which do not meet except at the tip. This feature develops only in the adults. Both species feed predominantly on molluscs. The roof of the upper bill is fringed with plate-like structures ("lamellae") in the African openbill, but these are absent in the Asian openbill. [2] [3]
The genus Anastomus was erected by the French naturalist Pierre Bonnaterre in 1791. [4] The type species was subsequently designated as the Asian openbill (Anastomus oscitans). [5] [6] The name Anastomus is from the Ancient Greek αναστομοω anastomoō meaning "to furnish with a mouth" or "with mouth wide-opened". [7]
There are two species of openbilled storks: [8]
Common name | Scientific name and subspecies | Range | Size and ecology | IUCN status and estimated population |
---|---|---|---|---|
African openbill | Anastomus lamelligerus Temminck, 1823 Two subspecies
| A resident breeder in Sub-Saharan Africa, including Madagascar | Size: measuring 80–94 cm (31–37 in) and weighing 1–1.3 kg (2.2–2.9 lb) Habitat: Diet: aquatic snails and fresh water mussels | LC |
Asian openbill | Anastomus oscitans (Boddaert, 1783) | A resident breeder in tropical southern Asia from India and Sri Lanka east to Southeast Asia. | Size: 68 cm (27 in) height (81 cm (32 in) long). Habitat: Diet: | LC |
Storks are large, long-legged, long-necked wading birds with long, stout bills. They belong to the family Ciconiidae, and make up the order Ciconiiformes. Ciconiiformes previously included a number of other families, such as herons and ibises, but those families have been moved to other orders.
The fulmars are tubenosed seabirds of the family Procellariidae. The family includes two extant species and two extinct fossil species from the Miocene.
Tropicbirds are a family, Phaethontidae, of tropical pelagic seabirds. They are the sole living representatives of the order Phaethontiformes. For many years they were considered part of the Pelecaniformes, but genetics indicates they are most closely related to the Eurypygiformes. There are three species in one genus, Phaethon. The scientific names are derived from Ancient Greek phaethon, "sun". They have predominantly white plumage with elongated tail feathers and small feeble legs and feet.
Buttonquail or hemipodes are members of a small family of birds, Turnicidae, which resemble, but are not closely related to, the quails of Phasianidae. They inhabit warm grasslands in Asia, Africa, Europe, and Australia. There are 18 species in two genera, with most species placed in the genus Turnix and a single species in the genus Ortyxelos.
The marabou stork is a large wading bird in the stork family Ciconiidae native to sub-Saharan Africa. It breeds in both wet and arid habitats, often near human habitation, especially landfill sites. It is sometimes called the "undertaker bird" due to its shape from behind: cloak-like wings and back, skinny white legs, and sometimes a large white mass of "hair". It has often been credited with the largest wingspan of any land bird, with an average of 2.6 metres (8.5 ft) and some recorded examples of up to 3.2 metres (10 ft).
The barred buttonquail or common bustard-quail is a buttonquail, one of a small family of birds which resemble, but are not closely related to, the true quails. This species is resident from India across tropical Asia to south China, Indonesia and the Philippines.
The black-necked stork is a tall long-necked wading bird in the stork family. It is a resident species across the Indian Subcontinent and Southeast Asia with a disjunct population in Australia. It lives in wetland habitats and near fields of certain crops such as rice and wheat where it forages for a wide range of animal prey. Adult birds of both sexes have a heavy bill and are patterned in white and irridescent blacks, but the sexes differ in the colour of the iris with females sporting yellow irises and males having dark-coloured irises. In Australia, it is known as a jabiru although that name refers to a stork species found in the Americas. It is one of the few storks that are strongly territorial when feeding and breeding.
The Asian openbill or Asian openbill stork is a large wading bird in the stork family Ciconiidae. This distinctive stork is found mainly in the Indian subcontinent and Southeast Asia. It is greyish or white with glossy black wings and tail and the adults have a gap between the arched upper mandible and recurved lower mandible. Young birds are born without this gap which is thought to be an adaptation that aids in the handling of snails, their main prey. Although resident within their range, they make long distance movements in response to weather and food availability.
Nyctibius is a genus of potoos, nocturnal birds in the family Nyctibiidae.
The peppershrikes are two species of passerine bird found in tropical Central and South America. They form the genus Cyclarhis, part of the vireo family.
Sabrewing is the common name given to hummingbirds classified in the genus Campylopterus. The group includes ten species. They are Neotropical birds that inhabit mountainous forests, generally near streams.
Nycticorax is a genus of night herons. The name Nycticorax means "night raven" and derives from the Ancient Greek νύκτος, nuktos "night" and κοραξ, korax, "raven". It refers to the largely nocturnal feeding habits of this group of birds, and the croaking crow-like call of the best known species, the black-crowned night heron.
Egretta is a genus of medium-sized herons, mostly breeding in warmer climates.
Mycteria is a genus of large subtropical and tropical storks with representatives in the Americas, east Africa, and southern and southeastern Asia. Two species have "ibis" in their scientific or old common names, but they are not related to these birds, and merely resemble some bald-headed ibises.
Leptoptilos is a genus of very large tropical storks, commonly known as adjutants. The name means thin (lepto) feather (ptilos). Two species are resident breeders in southern Asia, and the marabou stork is found in Sub-Saharan Africa.
Ciconia is a genus of birds in the stork family. Six of the seven living species occur in the Old World, but the maguari stork has a South American range. In addition, fossils suggest that Ciconia storks were somewhat more common in the tropical Americas in prehistoric times.
The scissor-tailed kite, also known commonly as the African swallow-tailed kite and the fork-tailed kite, is a bird of prey in the family Accipitridae. It is the only species placed in the genus Chelictinia. It is widespread in the northern tropics of Africa.
The African openbill is a species of stork from the family Ciconiidae. It is widely distributed in Sub-Saharan Africa and western regions of Madagascar. This species is considered common to locally abundant across its range, although it has a patchy distribution. Some experts consider there to be two sub-species, A. l. lamelligerus distributed on the continent and A. l. madagascariensis living on the island of Madagascar. Scientists distinguish between the two sub-species due to the more pronounced longitudinal ridges on the bills of adult A. l. madagascariensis. The Asian openbill found in Asia is the African openbill’s closest relative. The two species share the same notably large bill of a peculiar shape that gives them their name.
The Madagascar buttonquail is a species of bird in the buttonquail family, Turnicidae, that is endemic to Madagascar and a few small islands nearby. It is a ground-dwelling species with an unusual breeding biology in which the sexual dimorphism is reversed, with female being more brightly coloured than the male and it is the male that incubates the eggs and mainly cares for the young.
