Olive Thrush
The olive thrush (''Turdus olivaceus'') is, in its range, one of the most common members of the thrush family (Turdidae). It occurs in African highlands from southern Malawi and Mozambique in the north to the Cape of Good Hope in the south. It is a bird of forest and woodland, but has locally adapted to parks and large gardens in suburban areas. Taxonomy In 1760 the French zoologist Mathurin Jacques Brisson included a description of the olive thrush in his ''Ornithologie'' based on a specimen collected from the Cape of Good Hope in South Africa. He used the French name ''Le merle olive du Cap de Bonne Espérance'' and the Latin ''Merula Olivacea Capitis Bonae Spei''. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. When in 1766 the Swedish naturalist Carl Linnaeus updated his '' Systema Naturae'' for the twelfth edition, he added 240 species that had been previo ...

KwaZulu-Natal
KwaZulu-Natal (, also referred to as KZN and known as "the garden province") is a province of South Africa that was created in 1994 when the Zulu bantustan of KwaZulu ("Place of the Zulu" in Zulu) and Natal Province were merged. It is located in the southeast of the country, with a long shoreline on the Indian Ocean and sharing borders with three other provinces and the countries of Mozambique, Eswatini and Lesotho. Its capital is Pietermaritzburg, and its largest city is Durban. It is the second-most populous province in South Africa, with slightly fewer residents than Gauteng. Two areas in KwaZulu-Natal have been declared UNESCO World Heritage Sites: the iSimangaliso Wetland Park and the uKhahlamba Drakensberg Park. These areas are extremely scenic as well as important to the surrounding ecosystems. During the 1830s and early 1840s, the northern part of what is now KwaZulu-Natal was established as the Zulu Kingdom while the southern part was, briefly, the Boer Natalia Repu ...

Phillip Clancey
Phillip Alexander Clancey (26 September 1917 – 18 July 2001) was a leading authority on the ornithology of South Africa. Background and education Phillip Clancey was born, brought up and educated in Glasgow, Scotland. He studied at the Glasgow School of Art where his artistic skills were developed. Military service Clancey served in the 51st (Highland) Division with the Allied forces in Sicily and Italy during World War II, narrowly escaping death and being deafened in one ear by an artillery explosion. Following his death in 2001, Clancey's military medals, together with his "Gill Memorial Medal" were auctioned by City Coins, Cape Town, in 2006, on behalf of the Clancey Estate. These medals, including the Gill Memorial Medal were purchased on the auction by David R. Bennett - Chairman of the Durban Natural Science Museum Trust, and the medals now form part of the Bennett Military Medal Collection. Clancey's group of six military medals are to (Service Number) 913613 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fruit
In botany, a fruit is the seed-bearing structure in flowering plants that is formed from the ovary after flowering. Fruits are the means by which flowering plants (also known as angiosperms) disseminate their seeds. Edible fruits in particular have long propagated using the movements of humans and animals in a symbiotic relationship that is the means for seed dispersal for the one group and nutrition for the other; in fact, humans and many animals have become dependent on fruits as a source of food. Consequently, fruits account for a substantial fraction of the world's agricultural output, and some (such as the apple and the pomegranate) have acquired extensive cultural and symbolic meanings. In common language usage, "fruit" normally means the seed-associated fleshy structures (or produce) of plants that typically are sweet or sour and edible in the raw state, such as apples, bananas, grapes, lemons, oranges, and strawberries. In botanical usage, the term "fruit" also i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snail
A snail is, in loose terms, a shelled gastropod. The name is most often applied to land snails, terrestrial pulmonate gastropod molluscs. However, the common name ''snail'' is also used for most of the members of the molluscan class Gastropoda that have a coiled shell that is large enough for the animal to retract completely into. When the word "snail" is used in this most general sense, it includes not just land snails but also numerous species of sea snails and freshwater snails. Gastropods that naturally lack a shell, or have only an internal shell, are mostly called '' slugs'', and land snails that have only a very small shell (that they cannot retract into) are often called ''semi-slugs''. Snails have considerable human relevance, including as food items, as pests, and as vectors of disease, and their shells are used as decorative objects and are incorporated into jewelry. The snail has also had some cultural significance, tending to be associated with lethargy. The sn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Earthworm
An earthworm is a terrestrial invertebrate that belongs to the phylum Annelida. They exhibit a tube-within-a-tube body plan; they are externally segmented with corresponding internal segmentation; and they usually have setae on all segments. They occur worldwide where soil, water, and temperature allow. Earthworms are commonly found in soil, eating a wide variety of organic matter. This organic matter includes plant matter, living protozoa, rotifers, nematodes, bacteria, fungi, and other microorganisms. An earthworm's digestive system runs the length of its body. An earthworm respires (breathes) through its skin. It has a double transport system made of coelomic fluid that moves within the fluid-filled coelom and a simple, closed circulatory system. It has a central and peripheral nervous system. Its central nervous system consists of two ganglia above the mouth, one on either side, connected to a nerve running along its length to motor neurons and sensory cells in each s ...

Bird Egg
Bird eggs are laid by the females and range in quantity from one (as in condors) to up to seventeen (the grey partridge). Clutch size may vary latitudinally within a species. Some birds lay eggs even when the eggs have not been fertilized; it is not uncommon for pet owners to find their lone bird nesting on a clutch of infertile eggs, which are sometimes called wind-eggs. Anatomy All bird eggs contain the following components: * The embryo is the immature developing chick * The amnion is a membrane that initially covers the embryo and eventually fills with amniotic fluid, provides the embryo with protection against shock from movement * The allantois helps the embryo obtain oxygen and handles metabolic waste * The chorion, together with the amnion, forms the amniotic sac and encloses the amnion, vitellus, and the embryo * The vitellus, or yolk, is the nutrient-bearing portion of the egg, containing most of its fat, minerals, and many of its proteins and blood vessels * The alb ...

Bird Nest
A bird nest is the spot in which a bird lays and incubates its eggs and raises its young. Although the term popularly refers to a specific structure made by the bird itself—such as the grassy cup nest of the American robin or Eurasian blackbird, or the elaborately woven hanging nest of the Montezuma oropendola or the village weaver—that is too restrictive a definition. For some species, a nest is simply a shallow depression made in sand; for others, it is the knot-hole left by a broken branch, a burrow dug into the ground, a chamber drilled into a tree, an enormous rotting pile of vegetation and earth, a shelf made of dried saliva or a mud dome with an entrance tunnel. The smallest bird nests are those of some hummingbirds, tiny cups which can be a mere across and high. At the other extreme, some nest mounds built by the dusky scrubfowl measure more than in diameter and stand nearly tall. The study of birds' nests is known as ''caliology''. Not all bird species bui ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Animal Mimicry
In evolutionary biology, mimicry is an evolved resemblance between an organism and another object, often an organism of another species. Mimicry may evolve between different species, or between individuals of the same species. Often, mimicry functions to protect a species from predators, making it an anti-predator adaptation. Mimicry evolves if a receiver (such as a predator) perceives the similarity between a mimic (the organism that has a resemblance) and a model (the organism it resembles) and as a result changes its behaviour in a way that provides a selective advantage to the mimic. The resemblances that evolve in mimicry can be visual, acoustic, chemical, tactile, or electric, or combinations of these sensory modalities. Mimicry may be to the advantage of both organisms that share a resemblance, in which case it is a form of mutualism; or mimicry can be to the detriment of one, making it parasitic or competitive. The evolutionary convergence between groups is driven by th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taita Thrush
The Taita thrush (''Turdus helleri''), also known as the Taita olive thrush or Heller's ground thrush, is an endangered bird from the family of thrushes (Turdidae), endemic to the Taita Hills in Kenya. Description The Taita thrush was previously classified as subspecies of the olive thrush (''Turdus olivaceus''), but it is regarded as distinct species since 1985. It reaches a length between 20 and 22 centimetres. Head, breast and upperparts are coloured darkly. The underparts are white and the flanks have a rufous hue. The eyes and the bill exhibit a pale orange coloration. It was named after zoologist Edmund Heller (1875–1939) a workmate of the American ornithologist Edgar Alexander Mearns (1856–1916) who described this species scientifically in 1913. Distribution The Taita thrush is a forest-dependent endemic bird confined to four forests in the Taita Hills (in the south east of Kenya): Mbololo, Chawia, Yale and Ngangao. The forests cover a tiny 342 ha. Conservationists ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Abyssinian Thrush
The Abyssinian thrush (''Turdus abyssinicus'') is a passerine bird in the family Turdidae. It is also known as the African mountain thrush, or northern olive thrush In 2010, the species was confirmed as separate from the olive thrush (''Turdus olivaceus'') due to genetic differences. Their ranges do not overlap. The southern and northern populations may be distinct species. The Abyssinian thrush is found in Eritrea and other parts of the Horn of Africa, as well as an area to the southeast extending from the African Great Lakes region to north eastern Zambia and Malawi. Description It is long. This variable forest thrush is generally darker than the African thrush and has an orange (not yellow) bill. It is also darker than the Kurrichane thrush and has no malar stripes. Generally the birds get darker at higher altitudes. Distribution, habitat and habits The Abyssinian thrush occurs in the highlands of eastern Africa from South Sudan south to northern Mozambique. Its habitat inc ...
