Yellow-bellied Eremomela
The yellow-bellied eremomela (''Eremomela icteropygialis'') is an Old World warbler. However, the taxonomy of the "African warblers", an assemblage of usually species-poor and apparently rather ancient "odd warblers" from Africa is currently in a state of flux. Today, most taxonomists consider members in this genus members of the family Cisticolidae. The yellow-bellied eremomela is a common breeding species in Africa south of the Sahara in its habitat of open woodland, savannah, and dry scrub. Description The yellow-bellied eremomela is a very small bird 10 cm long and weighing around 9 g. Its upperparts are grey, becoming darker and more olive on the wings and tail. There is a thin pale grey supercilium and a blackish stripe through the eye. The grey breast shades into the lemon yellow belly. The bill is blackish. The subspecies vary in the extent and intensity of the yellow on the belly, and birds in western southern Africa have whitish throat and breast. The sexes ...

Mapungubwe National Park
Mapungubwe National Park is a national park in Limpopo Province, South Africa. It is located by the Kolope River, south of the confluence of the Limpopo and Shashe rivers and about to the NE of the Venetia Diamond Mine. The National Park borders Mapesu Private Game Reserve to the south. It abuts on the border with Botswana and Zimbabwe, and forms part of the Greater Mapungubwe Transfrontier Conservation Area. It was established in 1995 and covers an area of over . The park protects the historical site of Mapungubwe Hill, which was the capital of the Kingdom of Mapungubwe, as well as the wildlife and riverine forests along the Limpopo River. The Mapungubwe Hill was the site of a community dating back to the Iron Age. Evidences have shown that it was a prosperous community. Archaeologists also uncovered the famous golden rhino figurine from the site. It is one of the few places in Africa that has both meerkats and Nile crocodiles. Mapungubwe National Park is renowned for its sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Foraging
Foraging is searching for wild food resources. It affects an animal's fitness because it plays an important role in an animal's ability to survive and reproduce. Foraging theory is a branch of behavioral ecology that studies the foraging behavior of animals in response to the environment where the animal lives. Behavioral ecologists use economic models and categories to understand foraging; many of these models are a type of optimal model. Thus foraging theory is discussed in terms of optimizing a payoff from a foraging decision. The payoff for many of these models is the amount of energy an animal receives per unit time, more specifically, the highest ratio of energetic gain to cost while foraging. Foraging theory predicts that the decisions that maximize energy per unit time and thus deliver the highest payoff will be selected for and persist. Key words used to describe foraging behavior include ''resources'', the elements necessary for survival and reproduction which have a l ...

Eremomela
The eremomelas are a genus, ''Eremomela'', of passerines in the cisticola family Cisticolidae. The genus was previously placed with the larger Old World warbler family Sylviidae prior to that genus being broken up into several families. The genus contains eleven species, all of which are found in sub-Saharan Africa. They occupy a range of habitats, from arid scrub to lowland tropical forest. They are intermediate in appearance between crombecs and apalis, and measure between in length. The sexes are alike in size and plumage. The genus was erected by the Swedish zoologist Carl Jakob Sundevall in 1850. The type species is the yellow-bellied eremomela (''Eremomela icteropygialis''). The word ''Eremomela'' comes from the Ancient Greek ''erēmos'' for "desert" and ''melos'' for "song" or "melody". Species The genus contains 11 species: * Yellow-bellied eremomela (''Eremomela icteropygialis'') * Salvadori's eremomela (''Eremomela salvadori'') * Yellow-vented eremomela (''Eremomela fl ...

Salvadori's Eremomela
Salvadori's eremomela (''Eremomela salvadorii'') is a species of bird formerly placed in the Old World warbler assemblage, but now placed in the family Cisticolidae. It is found in Zaire, Gabon, Angola and Zambia. Its name commemorates Italian zoologist and ornithologist Tommaso Salvadori. It is sometimes considered conspecific with the yellow-bellied eremomela. Its natural habitats are subtropical or tropical dry forest A forest is an area of land dominated by trees.

Zambia
Zambia (), officially the Republic of Zambia, is a landlocked country at the crossroads of Central, Southern and East Africa, although it is typically referred to as being in Southern Africa at its most central point. Its neighbours are the Democratic Republic of the Congo to the north, Tanzania to the northeast, Malawi to the east, Mozambique to the southeast, Zimbabwe and Botswana to the south, Namibia to the southwest, and Angola to the west. The capital city of Zambia is Lusaka, located in the south-central part of Zambia. The nation's population of around 19.5 million is concentrated mainly around Lusaka in the south and the Copperbelt Province to the north, the core economic hubs of the country. Originally inhabited by Khoisan peoples, the region was affected by the Bantu expansion of the thirteenth century. Following the arrival of European explorers in the eighteenth century, the British colonised the region into the British protectorates of Barotseland-Nor ...

Zaire
Zaire (, ), officially the Republic of Zaire (french: République du Zaïre, link=no, ), was a Congolese state from 1971 to 1997 in Central Africa that was previously and is now again known as the Democratic Republic of the Congo. Zaire was, by area, the third-largest country in Africa (after Sudan and Algeria), and the 11th-largest country in the world. With a population of over 23 million inhabitants, Zaire was the most-populous officially Francophone country in Africa, as well as one of the most populous in Africa. The country was a one-party totalitarian military dictatorship, run by Mobutu Sese Seko and his ruling Popular Movement of the Revolution party. Zaire was established following Mobutu's seizure of power in a military coup in 1965, following five years of political upheaval following independence from Belgium known as the Congo Crisis. Zaire had a strongly centralist constitution, and foreign assets were nationalized. The period is sometimes referr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Invertebrate
Invertebrates are a paraphyletic group of animals that neither possess nor develop a vertebral column (commonly known as a ''backbone'' or ''spine''), derived from the notochord. This is a grouping including all animals apart from the chordate subphylum Vertebrata. Familiar examples of invertebrates include arthropods, mollusks, annelids, echinoderms and cnidarians. The majority of animal species are invertebrates; one estimate puts the figure at 97%. Many invertebrate taxa have a greater number and variety of species than the entire subphylum of Vertebrata. Invertebrates vary widely in size, from 50 μm (0.002 in) rotifers to the 9–10 m (30–33 ft) colossal squid. Some so-called invertebrates, such as the Tunicata and Cephalochordata, are more closely related to vertebrates than to other invertebrates. This makes the invertebrates paraphyletic, so the term has little meaning in taxonomy. Etymology The word "invertebrate" comes from the Latin word ''vertebra ...

Insect
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body ( head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monogamy
Monogamy ( ) is a form of dyadic relationship in which an individual has only one partner during their lifetime. Alternately, only one partner at any one time (serial monogamy) — as compared to the various forms of non-monogamy (e.g., polygamy or polyamory). The term is also applied to the social behavior of some animals, referring to the state of having only one mate at any one time. A monogamous relationship can be sexual or emotional, but it's usually both. Many modern relationships are monogamous. Terminology The word '' monogamy'' derives from the Greek μονός, ''monos'' ("alone"), and γάμος, ''gamos'' ("marriage").Cf. "Monogamy" in ''Britannica World Language Dictionary'', R.C. Preble (ed.), Oxford-London 1962, p. 1275:''1. The practice or principle of marrying only once. opp. to digamy now ''rare'' 2.
