White-headed Buffalo Weaver
The white-headed buffalo weaver or white-faced buffalo-weaver (''Dinemellia dinemelli'') is a species of passerine bird in the family Ploceidae native to East Africa. The buffalo part of its name derives from its habit of following the African buffalo, feeding on disturbed insects. Two subspecies are recognized. Taxonomy The white-headed buffalo weaver was first described by the German naturalist Eduard Rüppell in 1845. Subspecies Two subspecies of the white-headed buffalo weaver are now recognized. *''D. d. dinemelli'' ( E. Rüppell, 1845), northern part of its range: Sudan, Ethiopia, Somalia, Uganda, northern Kenya. *''D. d. boehmi'' ( A. Reichenow, 1885), southern part of its range: Kenya and Tanzania. Description The white-headed buffalo weaver is in length and in weight. In addition to its white head and underparts, the white-headed buffalo weaver has a vividly orange-red rump and undertail coverts. Its thighs are dark brown. Narrow white bands can be found on the win ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Serengeti National Park
The Serengeti National Park is a large national park in northern Tanzania that stretches over . It is located entirely in eastern Mara Region and north east portion of Simiyu Region and contains over of virgin savanna. The park was established in 1940. The Serengeti is well known for the largest annual animal migration in the world of over 1.5 million blue wildebeest and 250,000 zebra along with smaller herds of Thomas' Gazelle and eland. The national park is also home to the largest lion population in Africa. It is under threat from deforestation, population growth and ranching. Etymology The name "Serengeti" is an approximation of the word ''siringet'' used by the Maasai people for the area, which means "the place where the land runs on forever". History In 1930, an area of was designated as a game reserve in southern and eastern Serengeti. In the 1930s, the government of Tanganyika (territory), Tanganyika established a system of national parks compliant with the Conv ...

Savanna
A savanna or savannah is a mixed woodland- grassland (i.e. grassy woodland) ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses. According to '' Britannica'', there exists four savanna forms; ''savanna woodland'' where trees and shrubs form a light canopy, ''tree savanna'' with scattered trees and shrubs, ''shrub savanna'' with distributed shrubs, and ''grass savanna'' where trees and shrubs are mostly nonexistent.Smith, Jeremy M.B.. "savanna". Encyclopedia Britannica, 5 Sep. 2016, https://www.britannica.com/science/savanna/Environment. Accessed 17 September 2022. Savannas maintain an open canopy despite a high tree density. It is often believed that savannas feature widely spaced, scattered trees. However, in many savannas, tree densities are higher and trees are more regularly spaced than in f ...

African Pygmy-falcon
The pygmy falcon (''Polihierax semitorquatus'') or African pygmy falcon is a bird species native to eastern and southern Africa. It is the smallest bird of prey on the continent. Description Adult pygmy falcons are white below and on the face, grey above, and females having a chestnut back. There are white "eye spots" on the nape. Juveniles have a brown back, duller than adult females, with a rufous wash on the breast. The flight feathers of the wings are spotted black and white (more black above, more white below); the tail is barred black and white. The flight is low and undulating. In size, pattern, and the habit of perching upright on an exposed branch or treetop, this species resembles some shrikes. The call is "a high-pitched ''kikiKIK'', repeated" (Kenya) or "a 'chip-chip' and a 'kik-kik-kik-kik'" (southern Africa). Diet and feeding Pygmy falcons prey on reptiles and insects, but will occasionally prey on small birds as well as rodents. They hunt from a perch, swoop ...

Covert (feather)
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 row ...

Starling
Starlings are small to medium-sized passerine birds in the family Sturnidae. The Sturnidae are named for the genus '' Sturnus'', which in turn comes from the Latin word for starling, ''sturnus''. Many Asian species, particularly the larger ones, are called mynas, and many African species are known as glossy starlings because of their iridescent plumage. Starlings are native to Europe, Asia, and Africa, as well as northern Australia and the islands of the tropical Pacific. Several European and Asian species have been introduced to these areas, as well as North America, Hawaii, and New Zealand, where they generally compete for habitats with native birds and are considered to be invasive species. The starling species familiar to most people in Europe and North America is the common starling, and throughout much of Asia and the Pacific, the common myna is indeed common. Starlings have strong feet, their flight is strong and direct, and they are very gregarious. Their preferred ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Butterfly
Butterflies are insects in the macrolepidopteran clade Rhopalocera from the order Lepidoptera, which also includes moths. Adult butterflies have large, often brightly coloured wings, and conspicuous, fluttering flight. The group comprises the large superfamily Papilionoidea, which contains at least one former group, the skippers (formerly the superfamily "Hesperioidea"), and the most recent analyses suggest it also contains the moth-butterflies (formerly the superfamily "Hedyloidea"). Butterfly fossils date to the Paleocene, about 56 million years ago. Butterflies have a four-stage life cycle, as like most insects they undergo complete metamorphosis. Winged adults lay eggs on the food plant on which their larvae, known as caterpillars, will feed. The caterpillars grow, sometimes very rapidly, and when fully developed, pupate in a chrysalis. When metamorphosis is complete, the pupal skin splits, the adult insect climbs out, and after its wings have expanded and dried, ...

Beetle
Beetles are insects that form the order Coleoptera (), in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae (ladybirds or ladybugs) eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops. Beetles typically have a particularly hard ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gregarious
Sociality is the degree to which individuals in an animal population tend to associate in social groups (gregariousness) and form cooperative societies. Sociality is a survival response to evolutionary pressures. For example, when a mother wasp stays near her larvae in the nest, parasites are less likely to eat the larvae. Biologists suspect that pressures from parasites and other predators selected this behavior in wasps of the family Vespidae. This wasp behaviour evidences the most fundamental characteristic of animal sociality: parental investment. Parental investment is any expenditure of resources (time, energy, social capital) to benefit one's offspring. Parental investment detracts from a parent's capacity to invest in future reproduction and aid to kin (including other offspring). An animal that cares for its young but shows no other sociality traits is said to be ''subsocial''. An animal that exhibits a high degree of sociality is called a ''social animal''. The hi ...
