Pied Raven
The pied raven (''Corvus corax varius'' morpha ''leucophaeus'') is an extinct colour morph of the North Atlantic subspecies of the common raven that was only found on the Faroe Islands. The last confirmed record was in 1902. The pied raven had large areas of white feathering, most frequently on the head, the wings and the belly, and its beak was light brown. Apart from that, it looked like the all-black North Atlantic ravens (''C. c. varius'' morpha ''typicus''), which remains widespread in the Faroe Islands and are also found in Iceland. History The pied raven received binomial names such as ''Corvus leucophaeus'' (by Vieillot, 1817) and ''Corvus leucomelas'' (by Wagler, 1827). It is currently referred to as ''Corvus corax varius'' morpha ''leucophaeus''. Description In modern Faroese, the bird is called ''hvítravnur'' ("white raven"), older name ''gorpur bringu hvíti'' ("white-chested corbie"). Normal individuals of the subspecies ''varius'', which is found on Iceland a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

In biology, a type is a particular wikt:en:specimen, specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally associated. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set (mathematics), set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the ''International Code of Nomenclature for algae, fungi, and plants'' (ICN), the ...
