Zavattariornis
Stresemann's bushcrow (''Zavattariornis stresemanni''), also known as the Abyssinian pie, bush crow, Ethiopian bushcrow, or by its generic name ''Zavattariornis'', is a rather starling-like bird, which is currently thought to be member of the crow family, Corvidae, though this is uncertain. It is slightly larger than the North American blue jay and is a bluish-grey in overall colour which becomes almost white on the forehead. The throat and chest are creamy-white with the tail and wings a glossy black. The black feathers have a tendency to bleach to brown at their tips. The iris of the bird is brown and the eye is surrounded by a band of naked bright blue skin. The bill, legs, and feet are black. Feeding is usually in small groups and the bird takes mainly insects. Breeding usually starts in March, with the birds building their nest high in an acacia tree. The birds usually lay five to six cream eggs with lilac blotches. The nest itself is globular in shape with a tubular entranc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Corvidae
Corvidae is a cosmopolitan family of oscine passerine birds that contains the crows, ravens, rooks, jackdaws, jays, magpies, treepies, choughs, and nutcrackers. In colloquial English, they are known as the crow family or corvids. Currently, 133 species are included in this family. The genus ''Corvus'', including the crows, rooks, and ravens, makes up over a third of the entire family. Corvids (ravens) are the largest passerines. Corvids display remarkable intelligence for animals of their size, and are among the most intelligent birds thus far studied. Specifically, members of the family have demonstrated self-awareness in mirror tests (European magpies) and tool-making ability (e.g. crows and rooks), skills which until recently were thought to be possessed only by humans and a few other higher mammals. Their total brain-to-body mass ratio is equal to that of non-human great apes and cetaceans, and only slightly lower than that of humans.Birding in India and South AsiaCor ...

Yabello Wildlife Sanctuary
Yabelo Wildlife Sanctuary is a protected area and wildlife sanctuary in southern Ethiopia. It is located in the Borena Zone of the Oromia Region west of the town of Yabelo, having an area of 2,500 square kilometers and elevations ranging from 1430 to 2000 meters above sea level. The wildlife sanctuary borders on Borana National Park to the south. Ecology Flora The area of the sanctuary is notable for its red soils which have little organic matter. The general vegetation-type is '' Acacia'' savanna, the major trees being '' A. drepanolobium'' on black cotton soil, and '' A. brevispica'' and '' A. horrida'' on the slopes. There are also patches of ''Balanites aegyptiaca'', and several species of ''Commiphora'' and ''Terminalia'' at the lower altitudes. The higher parts of the hills were formerly covered with forest dominated by ''Juniperus procera'' and '' Olea europaea cuspidata''. Fauna Burchell's zebras are known to be abundant within the sanctuary along with small popul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Blue Jay
The blue jay (''Cyanocitta cristata'') is a passerine bird in the family Corvidae, native to eastern North America. It lives in most of the eastern and central United States; some eastern populations may be migratory. Resident populations are also in Newfoundland, Canada; breeding populations are found across southern Canada. It breeds in both deciduous and coniferous forests, and is common in residential areas. Its coloration is predominantly blue, with a white chest and underparts, and a blue crest; it has a black, U-shaped collar around its neck and a black border behind the crest. Males and females are similar in size and plumage, and plumage does not vary throughout the year. Four subspecies have been recognized. The blue jay feeds mainly on seeds and nuts, such as acorns, which it may hide to eat later; soft fruits; arthropods; and occasionally small vertebrates. It typically gleans food from trees, shrubs, and the ground, and sometimes hawks insects from the air. Blue ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palate
The palate () is the roof of the mouth in humans and other mammals. It separates the oral cavity from the nasal cavity. A similar structure is found in crocodilians, but in most other tetrapods, the oral and nasal cavities are not truly separated. The palate is divided into two parts, the anterior, bony hard palate and the posterior, fleshy soft palate (or velum). Structure Innervation The maxillary nerve branch of the trigeminal nerve supplies sensory innervation to the palate. Development The hard palate forms before birth. Variation If the fusion is incomplete, a cleft palate results. Function When functioning in conjunction with other parts of the mouth, the palate produces certain sounds, particularly velar, palatal, palatalized, postalveolar, alveolopalatal, and uvular consonants. History Etymology The English synonyms palate and palatum, and also the related adjective palatine (as in palatine bone), are all from the Latin ''palatum'' via Old French ''palat ...

Endemic Species
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sexually Dimorphic
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 d ...

Ornithologist
Ornithology is a branch of zoology that concerns the "methodological study and consequent knowledge of birds with all that relates to them." Several aspects of ornithology differ from related disciplines, due partly to the high visibility and the aesthetic appeal of birds. It has also been an area with a large contribution made by amateurs in terms of time, resources, and financial support. Studies on birds have helped develop key concepts in biology including evolution, behaviour and ecology such as the definition of species, the process of speciation, instinct, learning, ecological niches, guilds, island biogeography, phylogeography, and conservation. While early ornithology was principally concerned with descriptions and distributions of species, ornithologists today seek answers to very specific questions, often using birds as models to test hypotheses or predictions based on theories. Most modern biological theories apply across life forms, and the number of scientists who i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Erwin Stresemann
Erwin Friedrich Theodor Stresemann (22 November 1889, in Dresden – 20 November 1972, in East Berlin) was a German naturalist and ornithologist. Stresemann was an ornithologist of extensive breadth who compiled one of the first and most comprehensive accounts of avian biology of its time as part of the ''Handbuch der Zoologie'' (Handbook of Zoology). In the process of his studies on birds, he also produced one of the most extensive historical accounts on the development of the science of ornithology. He influenced numerous ornithologists around him and oversaw the development of ornithology in Germany as editor of the ''Journal für Ornithologie''. He also took an interest in poetry, philosophy and linguistics. He published a monograph on the Paulohi language based on studies made during his ornithological expedition to the Indonesian island. Early life Stresemann was born in Dresden to Richard, an apothecary and Marie. His grandfather Theodor owned the ''Zum Roten Adler'' phar ...

Edoardo Zavattari
Edoardo Zavattari (21 October 1883, Tortona – 17 February 1972) (born 21 October 1883 in Tortona, in the province of Alexandria, in Piedmont and died on 17 February 1972 in Genoa) was an Italian zoologist who was a director at the Institute of Zoology in the Sapienza University of Rome from 1935 to 1953. He supported fascism and anti-semitism on the basis of his ideas from biology and was a signatory to the " Manifesto della Razza". Biography His first academic role was as a professor at the University of Pavia and then at the University of Rome, Edoardo Zavattari was the author of more than 300 scientific publications. Between 1926 and 1959, he made several expeditions, visiting all the continents for research, in particular in the North-Eastern Africa. The specimens he collected, were placed into 122 packages, two of which are now part of the collection of the ''Museo Civico di Zoologia'' in Rome. In particular, he published ''Prodromo della fauna della Libia'' (1934). While h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
