Creurgops
''Creurgops'' is a genus of Neotropical birds in the tanager family Thraupidae. They are found in the Canopy (biology), canopy of humid montane forest in the Andes of South America. These are relatively large and heavy-billed tanagers. They are mainly Slate gray, slaty grey above and rufous below, except in the male slaty tanager where the underparts also are slaty grey. Males of both species have a crown patch, which is lacking in the females. They commonly participate in mixed-species flocks. Taxonomy and species list The genus ''Creurgops'' was introduced in 1858 by the English zoologist Philip Sclater to accommodate the newly described rufous-crested tanager (''Creurgops verticalis''). The genus name combines the Ancient Greek ''kreourgos '' meaning "butcher" with ''ōps'' meaning "appearance". The genus now contains two species. References * Restall, R. L., C. Rodner, & M. Lentino.

Rufous-crested Tanager
The rufous-crested tanager (''Creurgops verticalis'') is a species of bird in the family Thraupidae. It is found in Colombia, Ecuador, Peru and Venezuela. Its natural habitat is subtropical or tropical moist montane forest Montane ecosystems are found on the slopes of mountains.

Thraupidae
The tanagers (singular ) comprise the bird family Thraupidae, in the order Passeriformes. The family has a Neotropical distribution and is the second-largest family of birds. It represents about 4% of all avian species and 12% of the Neotropical birds. Traditionally, the family contained around 240 species of mostly brightly colored fruit-eating birds. As more of these birds were studied using modern molecular techniques, it became apparent that the traditional families were not monophyletic. '' Euphonia'' and '' Chlorophonia'', which were once considered part of the tanager family, are now treated as members of the Fringillidae, in their own subfamily ( Euphoniinae). Likewise, the genera '' Piranga'' (which includes the scarlet tanager, summer tanager, and western tanager), ''Chlorothraupis'', and '' Habia'' appear to be members of the cardinal family, and have been reassigned to that family by the American Ornithological Society.

Mixed-species Flock
A mixed-species feeding flock, also termed a mixed-species foraging flock, mixed hunting party or informally bird wave, is a flock of usually insectivorous birds of different species that join each other and move together while foraging. These are different from feeding aggregations, which are congregations of several species of bird at areas of high food availability. While it is currently unknown how mixed-species foraging flocks originate, researchers have proposed a few mechanisms for their initiation. Many believe that nuclear species play a vital role in mixed-species flock initiation. Additionally, the forest structure is hypothesized to play a vital role in these flocks' formation. In Sri Lanka, for example, vocal mimicry by the greater racket-tailed drongo might have a key role in the initiation of mixed-species foraging flocks, while in parts of the American tropics packs of foraging golden-crowned warblers might play the same role.

Ancient Greek
Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic period (), and the Classical period (). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Epic and Classical periods of the language. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regarded as a separate historical stage, although its earliest form closely resembles Attic Greek and its latest form approaches Medieval Greek. There were several regional dialects of Ancient Greek, of which Attic Greek developed into Koi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Philip Sclater
Philip Lutley Sclater (4 November 1829 – 27 June 1913) was an English lawyer and zoologist. In zoology, he was an expert ornithologist, and identified the main zoogeographic regions of the world. He was Secretary of the Zoological Society of London for 42 years, from 1860–1902. Early life Sclater was born at Tangier Park, in Wootton St Lawrence, Hampshire, where his father William Lutley Sclater had a country house. George Sclater-Booth, 1st Baron Basing was Philip's elder brother. Philip grew up at Hoddington House where he took an early interest in birds. He was educated in school at Twyford and at thirteen went to Winchester College and later Corpus Christi College, Oxford where he studied scientific ornithology under Hugh Edwin Strickland. In 1851 he began to study law and was admitted a Fellow of Corpus Christi College. In 1856 he travelled to America and visited Lake Superior and the upper St. Croix River, canoeing down it to the Mississippi. Sclater w ...

Slate Gray
Slate gray is a gray color with a slight azure tinge that is a representation of the average color of the material slate. As a tertiary color, slate is an equal mix of purple and green pigments. Slaty, referring to this color, is often used to describe birds. The first recorded use of ''slate gray'' as a color name in English was in 1705. __TOC__ Variations Light slate gray Displayed at right is the web color light slate gray.

Rufous
Rufous () is a color that may be described as reddish-brown or brownish- red, as of rust or oxidised iron. The first recorded use of ''rufous'' as a color name in English was in 1782. However, the color is also recorded earlier in 1527 as a diagnostic urine color. The word " rufous" is derived from the Latin ''rufus'', meaning "red", and is used as an adjective in the names of many animals—especially birds—to describe the color of their skin, fur, or plumage Plumage ( "feather") is a layer of feathers that covers a bird and the pattern, colour, and arrangement of those feathers. The pattern and colours of plumage differ between species and subspecies and may vary with age classes. Within species, ....
