Abyssinian Wheatear
The Abyssinian wheatear (''Oenanthe lugubris''), or Abyssinian black wheatear, is a species of bird in the family Muscicapidae. It is found from Ethiopia to southern Kenya and northeastern Tanzania. Taxonomy The Abyssinian wheatear was first formally Species description, described in 1837 as ''Saxicola lugubris'' by the German naturalist and explorer Eduard Rüppell with its Type locality (biology), type locality given as "the rocky valleys of the Abyssinian province of Simien Mountains, Simien, and on the volcanic hills around Gondar" (''Vorkommen in der felsigen Thälern der Abyssinischen provinz Simen, und auf der vulkanischen Hügeln um Gondar''). It is regarded, by some authorities, as being the same species as the mourning wheatear (''Oenanthe lugens'') of Northern Africa and the Middle East but the International Ornithological Committee, I.O.C. regard it as a valid species. The Abyssinian wheatear is regarded as being closely related to the Arabian wheatear (''Oenanthe lug ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eduard Rüppell
Wilhelm Peter Eduard Simon Rüppell (20 November 1794 – 10 December 1884) was a German Natural history, naturalist and List of explorers, explorer. Rüppell is occasionally transliterated to "Rueppell" for the English alphabet, due to german orthography. Biography Rüppell was born in Frankfurt am Main, the son of a prosperous banker, who was a partner in 'Rüppell und Harnier’s Bank'.

International Ornithological Committee
The International Ornithologists' Union, formerly known as the International Ornithological Committee, is a group of about 200 international ornithologists, and is responsible for the International Ornithological Congress and other international ornithological activities, undertaken by its standing committees. International Ornithological Congress The International Ornithological Congress series forms the oldest and largest international series of meetings of ornithologists. It is organised by the International Ornithologists' Union. The first meeting was in 1884; subsequent meetings were irregular until 1926 since when meetings have been held every four years, except for two missed meetings during and in the immediate aftermath of the Second World War.

Great Rift Valley
The Great Rift Valley is a series of contiguous geographic trenches, approximately in total length, that runs from Lebanon in Asia to Mozambique in Southeast Africa. While the name continues in some usages, it is rarely used in geology as it is considered an imprecise merging of separate though related rift and fault systems. This valley extends northward for 5,950 km through the eastern part of Africa, through the Red Sea, and into Western Asia. Several deep, elongated lakes, called ribbon lakes, exist on the floor of this rift valley: Lakes Malawi, Rudolf and Tanganyika are examples of such lakes. The region has a unique ecosystem and contains a number of Africa's wildlife parks. The term Great Rift Valley is most often used to refer to the valley of the East African Rift, the divergent plate boundary which extends from the Afar Triple Junction southward through eastern Africa, and is in the process of splitting the African Plate into two new and separate plates.

Mourning Wheatear RWD
Mourning is the expression of an experience that is the consequence of an event in life involving loss, causing grief, occurring as a result of someone's death, specifically someone who was loved although loss from death is not exclusively the cause of all experience of grief. The word is used to describe a complex of behaviours in which the bereaved participate or are expected to participate, the expression of which varies by culture. Wearing black clothes is one practice followed in many countries, though other forms of dress are seen. Those most affected by the loss of a loved one often observe a period of mourning, marked by withdrawal from social events and quiet, respectful behavior. People may follow religious traditions for such occasions. Mourning may apply to the death of, or anniversary of the death of, an important individual such as a local leader, monarch, religious figure, or member of family. State mourning may occur on such an occasion. In recent years, so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sexual Dimorphism
Sexual dimorphism is the condition where the sexes of the same animal and/or plant species exhibit different morphological characteristics, particularly characteristics not directly involved in reproduction. The condition occurs in most animals and some plants. Differences may include secondary sex characteristics, size, weight, colour, markings, or behavioural or cognitive traits. These differences may be subtle or exaggerated and may be subjected to sexual selection and natural selection. The opposite of dimorphism is ''monomorphism'', which is when both biological sexes are phenotypically indistinguishable from each other. Overview Ornamentation and coloration Common and easily identified types of dimorphism consist of ornamentation and coloration, though not always apparent. A difference in coloration of sexes within a given species is called sexual dichromatism, which is commonly seen in many species of birds and reptiles. Sexual selection leads to the exaggerated dim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Richard Meinertzhagen
Colonel Richard Meinertzhagen, CBE, DSO (3 March 1878 – 17 June 1967) was a British soldier, intelligence officer, and ornithologist. He had a decorated military career spanning Africa and the Middle East. He was credited with creating and executing the Haversack Ruse in October 1917, during the Sinai and Palestine Campaign of the First World War, but his participation in this matter has since been refuted. While early biographies lionized Meinertzhagen as a master of military strategy and espionage, later works such as ''The Meinertzhagen Mystery'' present him as a fraud for fabricating stories of his feats and speculated he murdered his wife (in addition to extra-judicial killings while in the colonial service). The discovery of stolen museum bird specimens resubmitted as original discoveries has raised serious doubts on the veracity of many of his ornithological records. Background and youth Meinertzhagen was born into a wealthy, socially connected British family. His f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anton Reichenow
Anton Reichenow (1 August 1847 in Charlottenburg – 6 July 1941 in Hamburg) was a German ornithologist and herpetologist. Reichenow was the son-in-law of Jean Cabanis, and worked at the Natural History Museum of Berlin from 1874 to 1921. He was an expert on African birds, making a collecting expedition to West Africa in 1872 and 1873, and writing ''Die Vögel Afrikas'' (1900–05). He was also an expert on parrots, describing all species then known in his book ''Vogelbilder aus Fernen Zonen: Abbildungen und Beschreibungen der Papageien'' (illustrated by Gustav Mützel, 1839–1893). He also wrote ''Die Vögel der Bismarckinseln'' (1899). He was editor of the ''Journal für Ornithologie'' from 1894 to 1921. A number of birds are named after him, including Reichenow's woodpecker and Reichenow's firefinch. His son Eduard Reichenow was a famous protozoologist. Reichenow is known for his classification of birds into six groups, described as "shortwings, swimmers, stiltbirds, skinb ...

Gustav Fischer (explorer)
Gustav Adolf Fischer (3 March 1848 – 11 November 1886, Berlin) was a German explorer of Africa. Biography He was born at Barmen. In 1876 he accompanied Clemens Denhardt's expedition to Zanzibar, where he settled as a physician. In the following year he explored Wituland and the southern Oromo country. In 1878 he continued his journey to Wapokomoland and along the Tana River to Massa. With the support of the Geographical Society of Hamburg he visited the Maasai country in 1882 and penetrated from the mouth of the Pangani River to Lake Naivasha. The Maasai prevented him from advancing further. Equipped with funds by the brother of Wilhelm Junker, an explorer, who with Emin Pasha and Gaetano Casati had been lost in the equatorial provinces, he organized a relief expedition which, however, was compelled to return after reaching Lake Victoria. Shortly after his return to Germany in 1886 he died of a bilious fever contracted during his journey. He is commemorated in the names ...

Species Complex
In biology, a species complex is a group of closely related organisms that are so similar in appearance and other features that the boundaries between them are often unclear. The taxa in the complex may be able to hybridize readily with each other, further blurring any distinctions. Terms that are sometimes used synonymously but have more precise meanings are cryptic species for two or more species hidden under one species name, sibling species for two (or more) species that are each other's closest relative, and species flock for a group of closely related species that live in the same habitat. As informal taxonomic ranks, species group, species aggregate, macrospecies, and superspecies are also in use. Two or more taxa that were once considered conspecific (of the same species) may later be subdivided into infraspecific taxa (taxa within a species, such as bacterial strains or plant varieties), that is complex but it is not a species complex. A species complex is in most cas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
