Bostrychia Hagedash
The hadeda ibis (''Bostrychia hagedash'') is an ibis native to Sub-Saharan Africa. It is named for its loud three to four note calls uttered in flight especially in the mornings and evenings when they fly out or return to their roost trees. Although not as dependent on water as some ibises, they are found near wetlands and often live in close proximity to humans, foraging in cultivated land and gardens. A medium-sized ibis with stout legs and a typical down-curved bill, the wing coverts are iridescent with a green or purple sheen. They are non-migratory but are known to make nomadic movements in response to rain particularly during droughts. Their ranges in southern Africa have increased with an increase in tree cover and irrigation in human-altered habitats. Taxonomy and systematics ''Tantalus hagedash'' was the scientific name proposed by John Latham in 1790 who described it from a specimen that had been collected at "Houteniquas", due north of Mossel Bay, by Anders Sparrma ...

Olive Ibis
The olive ibis (''Bostrychia olivacea'') is a species of ibis native to dense tropical forests in central Africa. Between 65 and 75 cm in length, it is a small ibis with olive plumage displaying a iridescent sheen. Four subspecies are recognized. Taxonomy and systematics Historically, the olive ibis was included in various genera such as ''Geronticus'', '' Comatibis'' and '' Harpiprion'' before finally being classified among the '' Bostrychia''.Salvadori T., 1903. On the ibis Olivacea of Dubus. ''Ibis'' 45: 178-188. It is also related to the Madagascar crested ibis ''Lophotibis cristata'' and ''Geronticus'' ibises.Hancock J. A., Kushlan J. A., Kahl M. P., 1992. ''Storks, Ibises and Spoonbills of the World''. Academic Press. Four subspecies of this ibis are currently recognised: ''Bostrychia olivacea olivacea'', ''B. o. cupreipennis'', ''B. o. akleyorum'' and ''B. o. rothschildi''.

Birds Of Sub-Saharan Africa
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. Birds ...

International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider pu ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Least Concern
A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the "Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15636) in the IUCN database still use the code "LR/lc", which indicates they have not been re-evaluate ...

Spot-breasted Ibis
The spot-breasted ibis (''Bostrychia rara'') is a small, forest-dwelling ibis found in African lowland forests and swampy forested areas. Its preference for dense rainforests in tropical Africa means that it is seldom seen and is vulnerable to deforestation. Description The spot-breasted ibis is a small, dark ibis (around ), with long legs and a long red bill. The adult has a long, loose crest at the back of its head, which is dark brown to black and glossy green. Its plumage varies, but most usually tends to be brownish-blue. The mantle is brown and edged buff, but with a shiny green color. The rump and tail are blue-green, and the tail is slightly blue-green. It has blue-black wings and black underwing. The scapulars and the inner secondaries have an iridescent bronze green. The best distinguishing feature is suggested by its name: the buff-spotted neck, breast and belly that are used as a diagnostic tool to identify the species. Otherwise, the upperparts are uniformly dark, wi ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

São Tomé Ibis
The São Tomé ibis (''Bostrychia bocagei''), also known as the dwarf olive ibis or the dwarf ibis, is endemism, endemic to São Tomé Island, São Tomé off the western coast of Central Africa and exists inside the Gulf of Guinea. Discovered in the 1800s by Francisco Newton, it was once thought to be a subspecies of the larger olive ibis, but is now classified as a distinct species. ''Bostrychia bocagei'' is a critically endangered ibis that measures approximately 2 ft in height. Living with 19 other species of endemic birds on the island, the dwarf ibis is one of 10 that are threatened with extinction. ''B. bocagei'' prefers the southern forests almost exclusively, living there in nests that are high up in the trees to avoid predators. Aside from predation, other common threats to the species include overhunting and habitat loss as a result of overexploitation of resources by the people of São Tomé. Although no specific conservation reforms have been enacted to help ''B. bo ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
