Salpornis Salvadori
The African spotted creeper (''Salpornis salvadori'') is a small passerine bird, which is a member of the subfamily Salpornithinae of the treecreeper family Certhiidae. It is found in sub-Saharan Africa in open deciduous forest and mango groves. It does not migrate other than local movements. The African spotted creeper has strongly spotted and barred plumage, clearly different from the treecreepers of the subfamily Certhiinae. It weighs up to , twice as much as treecreepers of similar length p to The African spotted creeper has a thin pointed down-curved bill, which it uses to extricate insects from bark, but it lacks the stiff tail feathers which the true treecreepers use to support themselves on vertical trees. Its nests and eggs are quite different from those of the Certhiinae. The nest is a cup placed on a horizontal branch, usually in a crotch, and camouflaged with spiders' egg sacs, caterpillar frass, and lichen. The clutch is usually of three eggs, which are blue ...

John Gerrard Keulemans
Johannes Gerardus Keulemans (J. G. Keulemans) (8 June 1842 – 29 March 1912) was a Dutch bird illustrator. For most of his life he lived and worked in England, illustrating many of the best-known ornithology books of the nineteenth century. Biography Keulemans was born in Rotterdam. As a young man he collected animal specimens for museums such as the Natural History Museum in Leiden, whose director, Hermann Schlegel, encouraged Keulemans and sent him on the 1864 expedition to West Africa. In 1869, he was persuaded by Richard Bowdler Sharpe to illustrate his '' Monograph of the Alcedinidae, or Family of Kingfishers'' (1868-1871) and to move to England, where he lived for the rest of his life. He was married twice, and had eight children by his first wife and seven children by his second wife. Only nine of his children reached adulthood. He also wrote topics on spirituality, and claimed he had a premonition at the moment of death of one of his sons. He died in Ilford, Essex (now ...

Salpornis
'' Salpornis '' is a genus of bird which is usually included in the family Certhiidae. The genus has in the past been included with the nuthatches in the family Sittidae or placed in a family of its own, the Salpornithidae. Molecular phylogenetic analyses show them to be definitely within the Certhioidea but still leaves some uncertainty about their placement in relation to the genera ''Sitta'', ''Tichodroma'' and ''Certhia''. While they appear similar to the treecreepers (''Certhia''), they do not use their tails to support them while climbing and some molecular evidence shows them to be closer to the nuthatches (''Sitta'') while another study suggests a closer relation to the wallcreeper ''Tichodroma muraria''. The generic name is derived from the Greek ''salpinktes'' for wren and ''ornis'' for bird. The tail has twelve feathers and is rounded at the tips. The nostril is exposed and there are no rictal bristles. The tongue ends in five bristles. The genus has two species with ...

Philippine Creeper
The Philippine creepers or rhabdornises are small passerine birds and form the genus ''Rhabdornis''. They are endemic to the Philippines. They do not migrate, other than to make local movements. Taxonomy The genus ''Rhabdornis'' was introduced in 1853 by German naturalist Ludwig Reichenbach to accommodate the stripe-headed rhabdornis. The name combines the Ancient Greek ''rhabdos'' meaning "stripe" with ''ornis'' meaning "bird." The relationship of the Philippine creepers to other bird species was formerly uncertain and the genus ''Rhabdornis'' was placed in its own family Rhabdornithinae. Molecular phylogenetic studies have revealed that the Philippine creepers are aberrant members of the starling family Sturnidae. The genus contains four species: * Stripe-headed rhabdornis, stripe-headed rhabdornis or stripe-sided rhabdornis, ''Rhabdornis mystacalis'' * Grand rhabdornis, long-billed rhabdornis or grand rhabdornis, ''Rhabdornis grandis'' * Stripe-breasted rhabdornis, plain-h ...

Australian Treecreeper
There are seven species of Australasian treecreeper in the passerine bird family Climacteridae. They are medium-small, mostly brown birds with patterning on their underparts, and all are endemic to Australia-New Guinea. They resemble, but are not closely related to, the Holarctic treecreepers. The family is one of several families identified by DNA–DNA hybridisation studies to be part of the Australo-Papuan songbird radiation. There is some molecular support for suggesting that their closest relatives are the large lyrebirds. As their name implies, treecreepers forage for insects and other small creatures living on and under the bark of trees, mostly eucalypts, though several species also hunt on the ground, through leaf-litter, and on fallen timber. Unlike the Holarctic treecreepers they do not use their tail for support when climbing tree trunks, only their feet. Australasian treecreepers nest in holes in trees. The species in the family hold breeding territories, although ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indian Spotted Creeper
The Indian spotted creeper (''Salpornis spilonota'') is a small passerine bird, which is a member of the subfamily Salpornithinae which is placed along with the treecreepers in the family Certhiidae. This small bird has a marbled black and white plumage that makes it difficult to spot as it forages on the trunks of dark, deeply fissured trees where it picks out insect prey using its curved bill. It is found in patchily distributed localities mainly in the dry scrub and open deciduous forests of northern and central peninsular India. It does not migrate. Their inclusion along with the treecreepers is not certain and some studies find them more closely related to the nuthatches while others suggest a close relation to the wallcreeper. They lack the stiff tail feathers of treecreepers and do not use their tail for supporting them while creeping vertically along tree trunks. Description The Indian spotted creeper has grey and white spotted and barred plumage, clearly different from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Frass
Frass refers loosely to the more or less solid excreta of insects, and to certain other related matter. Definition and etymology ''Frass'' is an informal term and accordingly it is variously used and variously defined. It is derived from the German word ''Fraß'', which means the food takeup of an animal.M. Clark and O. Thyen. The Oxford-Duden German Dictionary. Publisher: Oxford University Press 1999. The English usage applies to excreted residues of anything that insects had eaten, and similarly, to other chewed or mined refuse that insects leave behind. It does not generally refer to fluids such as honeydew, but the point does not generally arise, and is largely ignored in this article. Such usage in English originated in the mid-nineteenth century at the latest. Modern technical English sources differ on the precise definition, though there is little actual direct contradiction on the practical realities. One glossary from the early twentieth century speaks of "...excrem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
José Vicente Barbosa Du Bocage
José Vicente Barbosa du Bocage (2 May 1823 – 3 November 1907) was a Portuguese zoologist and politician. He was the curator of Zoology at the Museu Nacional de Lisboa in Lisbon. He published numerous works on mammals, birds, and fishes. In the 1880s he became the Minister of the Navy and later the Minister for Foreign Affairs for Portugal. The zoology collection at the Lisbon Museum is called the Bocage Museum in his honor. Du Bocage was born in Funchal, Madeira. He studied at the University of Coimbra from 1839 to 1846. He became lecturer of the chair of Zoology at the Polytechnic School, Lisbon (later the Science Faculty of the University of Lisbon) in 1851, where he taught for more than 30 years. In 1858, he became also the scientific director and curator of Zoology of the Natural History Museum of the Polytechnic School. which was established as a support for the chair. His work at the Museum consisted in acquiring, describing and coordinating collections, many of whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Certhia
'' Certhia '' is the genus of birds containing the typical treecreepers, which together with the African and Indian spotted creepers make up the family Certhiidae. The typical treecreepers occur in many wooded parts of the North Temperate Zone. They do not normally migrate other than for local movements, such as altitudinal migrations in the Himalayan species. The treecreepers are small woodland birds, very similar in appearance (so they can present serious identification problems where two species occur together). They are brown with streaks above and white below. They have thin pointed down-curved bills, which they use to extricate insects from bark. They have stiff, pointed tail feathers, like woodpeckers and woodcreepers, which they use to support themselves on vertical trees. All the tail feathers but the two central ones are molted in quick succession; the two central ones are not molted till the others grow back, so the bird can always prop itself with its tail. They ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird Migration
Bird migration is the regular seasonal movement, often north and south along a flyway, between breeding and wintering grounds. Many species of bird migrate. Migration carries high costs in predation and mortality, including from hunting by humans, and is driven primarily by the availability of food. It occurs mainly in the northern hemisphere, where birds are funneled onto specific routes by natural barriers such as the Mediterranean Sea or the Caribbean Sea. Migration of species such as storks, turtle doves, and swallows was recorded as many as 3,000 years ago by Ancient Greek authors, including Homer and Aristotle, and in the Book of Job. More recently, Johannes Leche began recording dates of arrivals of spring migrants in Finland in 1749, and modern scientific studies have used techniques including bird ringing and satellite tracking to trace migrants. Threats to migratory birds have grown with habitat destruction, especially of stopover and wintering sites, as wel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
