Maghreb Owl
The Maghreb owl (''Strix mauritanica'') is an owl of the earless owl genus, ''Strix''. It occurs in northwestern Africa from Morocco to Tunisia and Mauritania. It was previously considered a subspecies of the tawny owl. This species is a rather dark grey-brown with no evidence of morph colour variation. It is slightly dull, cooler and more uniform hue overall than ''Strix aluco aluco'' or ''Strix aluco sylvatica''. Study of genetic materials, including phylogeography, and the species dispersal behaviour, supports the division of ''Strix aluco maurtanica'' from the European subspecies, and it may even form its own species, with the Strait of Gibraltar The Strait of Gibraltar ( ar, مضيق جبل طارق, Maḍīq Jabal Ṭāriq; es, Estrecho de Gibraltar, Archaism, Archaic: Pillars of Hercules), also known as the Straits of Gibraltar, is a narrow strait that connects the Atlantic Ocean to ... as a natural gap between the ranges.Doña, J., Ruiz-Ruano, F.

Harry Forbes Witherby
Harry Forbes Witherby, MBE, FZS, MBOU (7 October 1873 – 11 December 1943) was a noted British ornithologist, author, publisher and founding editor (in 1907) of the magazine ''British Birds''. Personal life Harry was the second surviving son of Henry Forbes Witherby (1836–1907) of Holmehurst, Burley, Hants, the owner of the legal and maritime stationer Witherby and Co., employing 169 men who retired from the family business in 1899 to focus on his interests in painting and ornithology, leaving it to be run by his sons. After leaving school Witherby entered his old family publishing firm of Witherby, from which he retired in 1936, but resumed work again after the outbreak of the second world war. The family firm of H F and G Witherby, originally printers, began to publish bird books early in the 20th century. From an early age Witherby devoted himself to the study of ornithology, travelling extensively, including visits to Iran, the Kola Peninsula, and the White Nile. H ...

Earless Owl
''Strix'' is a genus of owls in the typical owl family (Strigidae), one of the two generally accepted living families of owls, with the other being the barn-owl (Tytonidae). Common names are earless owls or wood owls, though they are not the only owls without ear tufts, and " wood owl" is also used as a more generic name for forest-dwelling owls. Neotropical birds in the genus ''Ciccaba'' are sometimes included in ''Strix''. These are medium-sized to large, robustly built, powerful owls. They do not have ear tufts and most are highly nocturnal woodland birds. Most prey on small mammals, birds, and reptiles. Most owls in the genus ''Strix'' can be distinguished from other genera of owls through their hooting vocalization and lack of visible ears. The Latin genus name ''Strix'' referred to a mythical vampiric owl-monster believed to suck the blood of infants. Although the genus ''Strix'' was established for the earless owls by Linnaeus in 1758, many applied the term to other o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...

Morocco
Morocco (),, ) officially the Kingdom of Morocco, is the westernmost country in the Maghreb region of North Africa. It overlooks the Mediterranean Sea to the north and the Atlantic Ocean to the west, and has land borders with Algeria to the east, and the disputed territory of Western Sahara to the south. Mauritania lies to the south of Western Sahara. Morocco also claims the Spanish exclaves of Ceuta, Melilla and Peñón de Vélez de la Gomera, and several small Spanish-controlled islands off its coast. It spans an area of or , with a population of roughly 37 million. Its official and predominant religion is Islam, and the official languages are Arabic and Berber; the Moroccan dialect of Arabic and French are also widely spoken. Moroccan identity and culture is a mix of Arab, Berber, and European cultures. Its capital is Rabat, while its largest city is Casablanca. In a region inhabited since the Paleolithic Era over 300,000 years ago, the first Moroccan st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tawny Owl
The tawny owl (''Strix aluco''), also called the brown owl, is commonly found in woodlands across Europe to western Siberia, and has seven recognized subspecies. It is a stocky, medium-sized owl, whose underparts are pale with dark streaks, and whose upper body may be either brown or grey. (In several subspecies, individuals may be of either color.) The tawny owl typically makes its nest in a tree hole where it can protect its eggs and young against potential predators. It is non-migratory and highly territorial: as a result, when young birds grow up and leave the parental nest, if they cannot find a vacant territory to claim as their own, they will often starve. The tawny owl is a nocturnal bird of prey. It is able to hunt successfully at night because of its vision and hearing adaptations and its ability to fly silently. It usually hunts by dropping suddenly from a perch and seizing its prey, which it swallows whole. It hunts mainly rodents, although in urbanized areas its ...

Phylogeography
Phylogeography is the study of the historical processes that may be responsible for the past to present geographic distributions of genealogical lineages. This is accomplished by considering the geographic distribution of individuals in light of genetics, particularly population genetics. This term was introduced to describe geographically structured genetic signals within and among species. An explicit focus on a species' biogeography/biogeographical past sets phylogeography apart from classical population genetics and phylogenetics. Past events that can be inferred include population expansion, population bottlenecks, vicariance, dispersal, and migration. Recently developed approaches integrating coalescent theory or the genealogical history of alleles and distributional information can more accurately address the relative roles of these different historical forces in shaping current patterns. Development The term phylogeography was first used by John Avise in his 1987 work ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strait Of Gibraltar
The Strait of Gibraltar ( ar, مضيق جبل طارق, Maḍīq Jabal Ṭāriq; es, Estrecho de Gibraltar, Archaism, Archaic: Pillars of Hercules), also known as the Straits of Gibraltar, is a narrow strait that connects the Atlantic Ocean to the Mediterranean Sea and separates the Iberian Peninsula in Europe from Morocco in Africa. The two continents are separated by of ocean at the Strait's narrowest point between Punta de Tarifa, Point Marroquí in Spain and Point Cires in Morocco. Ferries cross between the two continents every day in as little as 35 minutes. The Strait's depth ranges between which possibly interacted with the lower mean sea level of the last major glaciation 20,000 years ago when the level of the sea is believed to have been lower by .

Wing Chord (biology)
Wing chord is an anatomical measurement of a bird's wing. The measurement is taken with the wing bent at a 90-degree angle, from the most prominent point of the wrist joint to the most prominent point of the longest primary feather. It is often taken as a standard measurement of the proportions of a bird and used to differentiate between species and subspecies. See also * Bird measurement Bird measurement or bird biometrics are approaches to quantify the size of birds in scientific studies. The measurements of the lengths of specific parts and the weights of birds varies between species, populations within species, between the sex ... References {{Bird-stub Bird anatomy ...

Birds Of North Africa
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. Birds ...
