Southern Yellow-billed Hornbill
The southern yellow-billed hornbill (''Tockus leucomelas'') is a hornbill found in southern Africa. Yellow-billed hornbills feed mainly on the ground, where they forage for seeds, small insects, spiders and scorpions. This hornbill species is a common and widespread resident of dry thornveldt and broad-leafed woodlands. They can often be seen along roads and water courses. Description left, Adult female in Mapungubwe National Park, South Africa. She has a shorter bill, with shorter casque, than the male. It is a medium-sized bird, in length, in weight and is characterized by a long yellow and down-curved beak. This beak is huge in comparison to its body and can account for up 1/6th of the entire body length. Male beaks are on average 90 mm long while female beaks are an average of 74 mm. Males are generally bigger than females but there is overlap between the sexes. The size difference of the beak is a fairly reliable way of differentiating sex in wild hornbills. ...

Hornbills
Hornbills (Bucerotidae) are a 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 on the upper mandible. Both the common English and the scientific name of the family refer to the shape of the bill, "buceros" being "cow horn" in Greek. Hornbills have a two-lobed kidney. They are the only birds in which the first and second neck vertebrae (the atlas and 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 insular species of hornbill with small ranges are threatened with extinction, namely in Southeast Asia. In the Neotropical realm, toucans occupy the hornbills' ecological niche, an example of convergent evolution. De ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gait
Gait is the pattern of movement of the limbs of animals, including humans, during locomotion over a solid substrate. Most animals use a variety of gaits, selecting gait based on speed, terrain, the need to maneuver, and energetic efficiency. Different animal species may use different gaits due to differences in anatomy that prevent use of certain gaits, or simply due to evolved innate preferences as a result of habitat differences. While various gaits are given specific names, the complexity of biological systems and interacting with the environment make these distinctions "fuzzy" at best. Gaits are typically classified according to footfall patterns, but recent studies often prefer definitions based on mechanics. The term typically does not refer to limb-based propulsion through fluid mediums such as water or air, but rather to propulsion across a solid substrate by generating reactive forces against it (which can apply to walking while underwater as well as on land). Due to th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Etosha National Park
Etosha National Park is a national park in northwestern Namibia and one of the largest national parks in Africa. It was proclaimed a game reserve in March 1907 in Ordinance 88 by the Governor of German South West Africa, Friedrich von Lindequist. It was designated as ''Wildschutzgebiet'' in 1958, and was elevated to the status of a national park in 1967 by an act of parliament of the Republic of South Africa. It spans an area of and gets its name from the large Etosha pan which is almost entirely within the park. With an area of , the Etosha pan covers 23% of the total area of the national park. The area is home to hundreds of species of mammals, birds and reptiles, including several threatened and endangered species such as the black rhinoceros. The park is located in the Kunene region and shares boundaries with the regions of Oshana, Oshikoto and Otjozondjupa. History Areas north of the Etosha pan were inhabited by Ovambo people, while various Otjiherero-speaking groups ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Courtship Feeding
A nuptial gift is a nutritional gift given by one partner in some animals' sexual reproduction practices. Formally, a nuptial gift is a material presentation to a recipient by a donor during or in relation to sexual intercourse that is not simply gametes in order to improve the reproductive fitness of the donor. Often, such a gift will improve the fitness of the recipient as well. This definition implies neutral gifts, costly gifts and beneficial gifts regarding the fitness of the recipient. Nuptial gifting is at the intersection of sexual selection, nutritional ecology, and life history theory, creating a link between the three. Edible and inedible nuptial gifts Many nuptial gifts are a source of nutrition for the recipient. In many species of animals, including birds, insects, and spiders, this takes the form of a food item that is transferred from a male to a female just prior to copulation. This is a behavior known as courtship feeding. Inedible tokens may include item ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Breviceps
''Breviceps'' is a genus of frogs in the family Brevicipitidae. Species in the genus ''Breviceps'' are commonly known as rain frogs or short-headed frogs. They occur in arid to semiarid climates of East Africa and Southern Africa. Taxonomy The genus ''Breviceps'' consists of 20 species, of which most occur in southern Africa. There are five species found in the Western Cape, '' B. gibbosus'', '' B. fuscus'' (black rain frog), '' B. rosei'' (Rose's rain frog), '' B. montanus'' (mountain rain frog) and '' B. acutirostris'' (strawberry rain frog). Two species are found in arid areas and other species are found in the eastern and northern parts of southern Africa. Description Species of the genus ''Breviceps'' are sexually dimorphic: males are much smaller than females. This prevents normal amplexus; instead, males and females produce an adhesive secretion from the skin that allows them to "stick" together during mating. Ecology and behaviour Species of the genus ''Breviceps'' sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Caterpillar
Caterpillars ( ) are the larval stage of members of the order Lepidoptera (the insect order comprising butterflies and moths). As with most common names, the application of the word is arbitrary, since the larvae of sawflies (suborder Symphyta) are commonly called caterpillars as well. Both lepidopteran and symphytan larvae have eruciform body shapes. Caterpillars of most species eat plant material ( often leaves), but not all; some (about 1%) eat insects, and some are even cannibalistic. Some feed on other animal products. For example, clothes moths feed on wool, and horn moths feed on the hooves and horns of dead ungulates. Caterpillars are typically voracious feeders and many of them are among the most serious of agricultural pests. In fact, many moth species are best known in their caterpillar stages because of the damage they cause to fruits and other agricultural produce, whereas the moths are obscure and do no direct harm. Conversely, various species of caterpi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
