Dark Batis
The dark batis (''Batis crypta'') is a small passerine bird belonging to the genus '' Batis'' in the wattle-eye family, Platysteiridae. It is found in highland forest in south-west Tanzania, northern Malawi, and northern Mozambique. These birds were formerly thought to be forest batises (''B. mixta'') but in 2006 were described as a new species based on differences in morphology and mitochondrial DNA from those birds in northern Tanzania and Kenya. Description The dark batis is about in length and weighs . It has a dark bill and legs and red eyes. The male is white below with a broad black breastband. Above it has a dark grey crown, grey back with some black feather-tips, a black face-mask and black wings with a white stripe. The female has a greyish crown, brownish back, dark mask, slight white supercilium and a narrow rufous stripe on the wing. Below it has a rufous chin-spot and breast with whitish tips to some of the feathers. The forest batis has a slightly shorter tail. ...

Supercilium
The supercilium is a plumage feature found on the heads of some bird species. It is a stripe which runs from the base of the bird's beak above its eye, finishing somewhere towards the rear of the bird's head.Dunn and Alderfer (2006), p. 10 Also known as an "eyebrow", it is distinct from the eyestripe, which is a line that runs across the lores, and continues behind the eye. Where a stripe is present only above the lores, and does not continue behind the eye, it is called a supraloral stripe or simply supraloral. On most species which display a supercilium, it is paler than the adjacent feather tracts. The colour, shape or other features of the supercilium can be useful in bird identification. For example, the supercilium of the dusky warbler, an Old World warbler species, can be used to distinguish it from the very similar Radde's warbler. The dusky warbler's supercilium is sharply demarcated, whitish and narrow in front of the eye, becoming broader and more buffy towards the ...

Termite
Termites are small insects that live in colonies and have distinct castes (eusocial) and feed on wood or other dead plant matter. Termites comprise the infraorder Isoptera, or alternatively the epifamily Termitoidae, within the order Blattodea (along with cockroaches). Termites were once classified in a separate order from cockroaches, but recent phylogenetic studies indicate that they evolved from cockroaches, as they are deeply nested within the group, and the sister group to wood eating cockroaches of the genus ''Cryptocercus''. Previous estimates suggested the divergence took place during the Jurassic or Triassic. More recent estimates suggest that they have an origin during the Late Jurassic, with the first fossil records in the Early Cretaceous. About 3,106 species are currently described, with a few hundred more left to be described. Although these insects are often called "white ants", they are not ants, and are not closely related to ants. Like ants and some bees a ...

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 from eggs. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Njesi Highlands
The Njesi Highlands (Portuguese: ''Serra Jeci'') are a range of mountains in northern Mozambique. Geography The highlands rise east of Lake Malawi in the western portion of Mozambique's Niassa Province. They are north of Lichinga, the provincial capital. The highest peaks are three inselbergs, the Njesi Plateau (1,843 m), Mount Chitagal (1,784 m), and Mount Sanga (1,782 m). The three peaks form part of a ridgeline that runs southwest to northeast. The Njesi Plateau is the southernmost peak, 30km from Mount Chitagal, and Mount Sanga is 25 km north of Mount Chitagal.Samuel EI Jones, Gabriel A Jamie, Emidio Sumbane & Merlijn Jocque (2020) The avifauna, conservation and biogeography of the Njesi Highlands in northern Mozambique, with a review of the country’s Afromontane birdlife, Ostrich, 91:1, 45-56, DOI: 10.2989/00306525.2019.1675795 Lake Malawi known in Mozambique as Lake Niassa, lies in the East African Rift, and the ridge and the highlands form part of the rift valley's easte ...

Uluguru Mountains
The Uluguru mountains are a mountain range in eastern Tanzania, named after the Luguru tribe. The main portion of the Uluguru mountains is a ridge running roughly north-south and rising to altitude at its highest point. On the main Uluguru range, 50 villages touch the forest boundary and over 151,000 people are found within the mountain area, often at increasing densities at higher altitudes up to the forest boundary. Geography The Ulugurus lie 200 km inland from the Indian Ocean. They are part of a chain of mountains in eastern Africa collectively called the Eastern Arc Mountains, which include the Taita Hills, Pare Mountains, Usambara Mountains, Nguru Mountains, Rubeho, Ukaguru, Udzungwa Mountains and Mahenge Mountains. Vegetation The vegetation of the Uluguru main ridge and outlying blocks is extremely variable.

East Africa
East Africa, Eastern Africa, or East of Africa, is the eastern subregion of the African continent. In the United Nations Statistics Division scheme of geographic regions, 10-11-(16*) territories make up Eastern Africa: Due to the historical Omani Empire and colonial territories of the British East Africa Protectorate and German East Africa, the term ''East Africa'' is often (especially in the English language) used to specifically refer to the area now comprising the three countries of Kenya, Tanzania, and Uganda. However, this has never been the convention in many other languages, where the term generally had a wider, strictly geographic context and therefore typically included Djibouti, Eritrea, Ethiopia, and Somalia.Somaliland is not included in the United Nations geoscheme, as it is internationally recognized as a part of Somalia. *Tanzania, Kenya, Uganda, Rwanda, Burundi, Democratic Republic of Congo and South Sudan are members of the East African Community.

Bird Song
Bird vocalization includes both bird calls and bird songs. In non-technical use, bird songs are the bird sounds that are melodious to the human ear. In ornithology and birding, songs (relatively complex vocalizations) are distinguished by function from calls (relatively simple vocalizations). Definition The distinction between songs and calls is based upon complexity, length, and context. Songs are longer and more complex and are associated with territory and courtship and mating, while calls tend to serve such functions as alarms or keeping members of a flock in contact. Other authorities such as Howell and Webb (1995) make the distinction based on function, so that short vocalizations, such as those of pigeons, and even non-vocal sounds, such as the drumming of woodpeckers and the "winnowing" of snipes' wings in display flight, are considered songs. Still others require song to have syllabic diversity and temporal regularity akin to the repetitive and transformative patte ...

Journal Of Ornithology
The ''Journal of Ornithology'' (formerly ''Journal für Ornithologie'') is a scientific journal published by Springer Science+Business Media on behalf of the Deutsche Ornithologen-Gesellschaft. It was founded by Jean Cabanis in 1853, becoming the official journal of the Deutsche Ornithologen-Gesellschaft in 1854. The first issue was produced in January 1853 and Cabanis noted that although there were specialist journals in entomology and conchology that there was nothing to deal with ornithology in Germany. Among the first essays published in the journal, was an essay by Reichenbach on the concept of species. According to the ''Journal Citation Reports'', the journal has a 2012 impact factor of 1.632.
