Lake Baringo
Lake Baringo is, after Lake Turkana, the most northern of the Kenyan Rift Valley lakes, with a surface area of and an elevation of . The lake is fed by several rivers: the Molo, Perkerra and Ol Arabel. It has no obvious outlet; the waters are assumed to seep through lake sediments into the faulted volcanic bedrock. It is one of the two freshwater lakes in the Rift Valley in Kenya, the other being Lake Naivasha. See "Kenya designates freshwater lake in Great Rift Valley," aRamsar 2009 - 2002 The lake is in a remote hot and dusty area with over 470 species of birds, occasionally including migrating flamingos. A Goliath heronry is located on a rocky islet in the lake known as Gibraltar. Description The lake is part of the East African Rift system. The Tugen Hills, an uplifted fault block of volcanic and metamorphic rocks, lies west of the lake. The Laikipia Escarpment lies to the east. Water flows into the lake from the Mau Hills and Tugen Hills. It is a critical habitat a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hornbill
Hornbills (Bucerotidae) are a family (biology), family of bird found in tropical and subtropical Africa, Asia and Melanesia. They are characterized by a long, down-curved bill which is frequently brightly coloured and sometimes has a Casque (anatomy), casque on the upper mandible. Both the common English (language), English and the scientific name of the family refer to the shape of the bill, "buceros" being "cow horn" in Greek language, Greek. Hornbills have a two-lobed kidney. They are the only birds in which the first and second vertebra, neck vertebrae (the atlas (anatomy), atlas and axis (anatomy), axis respectively) are fused together; this probably provides a more stable platform for carrying the bill. The family is omnivorous, feeding on fruit and small animals. They are monogamous breeders nesting in natural cavities in trees and sometimes cliffs. A number of mainly Island, insular species of hornbill with small ranges are Threatened species, threatened with extinction, ...

Wing-coverts
A covert feather or tectrix on a bird is one of a set of feathers, called coverts (or ''tectrices''), which, as the name implies, cover other feathers. The coverts help to smooth airflow over the wings and tail. Ear coverts The ear coverts are small feathers behind the bird's eye which cover the ear opening (the ear of a bird has no external features) Tail coverts The uppertail and undertail coverts cover the base of the tail feathers above and below. Sometimes these coverts are more specialised. The "tail" of a peacock is made of very elongated uppertail coverts. Wing coverts The upperwing coverts fall into two groups: those on the inner wing, which overlay the secondary flight feathers, known as the secondary coverts, and those on the outerwing, which overlay the primary flight feathers, the primary coverts. Within each group, the feathers form a number of rows. The feathers of the outermost, largest, row are termed greater (primary-/secondary-) coverts; those in the next ro ...

Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Von Der Decken's Hornbill
Von der Decken's hornbill (''Tockus deckeni'') is a hornbill found in East Africa, especially to the east of the East African Rift, from Ethiopia south to Tanzania. It is found mainly in thorn scrub and similar arid habitats. Jackson's hornbill is often treated as a subspecies of it. It was named after the German explorer Baron Karl Klaus von der Decken (1833–1865). Description This species is a small hornbill with blackish upperparts and mainly whitish underparts and head. It has a long tail and a long curved bill which lacks a casque. It is similar to the red-billed hornbill except for the bill colour and the lack of spotting on the wing coverts in both male and female. The species shows sexual dimorphism; the female has a black bill, whereas the male has a red bill with a cream tip and a black cutting edge. Breeding During incubation, the female lays two or three white eggs in a tree hole, which is blocked off with a cement made of mud, droppings and fruit pulp. There is ...
