Tamaulipas Crow
The Tamaulipas crow (''Corvus imparatus'') is a crow found in northeastern Mexico and southern Texas. Description It is a relatively small and sleek looking crow, in length. It has very glossy dark, bluish plumage, which appears soft and silky. The bill is quite slender and black, as are the legs and feet. The Chihuahuan raven, a much larger and very different bird, is the only crow it commonly occurs alongside. Taxonomy The Sinaloa crow (''Corvus sinaloae'') appears to be genetically extremely close to this bird and can be considered the western form of it though the voice is quite different, indeed a third species, the fish crow (''Corvus ossifragus'') of the southeastern United States appears to be very closely related to them also and the three may be considered a superspecies. Distribution and habitat Occurring in a relatively small area in northeastern Mexico, it inhabits near desert scrub and bushland and includes farms, small towns and villages in its range. It also oc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Crow
A crow is a bird of the genus ''Corvus'', or more broadly, a synonym for all of ''Corvus''. The word "crow" is used as part of the common name of many species. The related term "raven" is not linked scientifically to any certain trait but is rather a general grouping for larger-sized species of ''Corvus''. The collective name for a group of crows is a "murder".

Plumage
Plumage () 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, there can be different colour morph (zoology), morphs. The placement of feathers on a bird is not haphazard but rather emerges in organized, overlapping rows and groups, and these are known by standardized names. Most birds moult twice a year, resulting in a breeding or ''nuptial plumage'' and a ''basic plumage''. Many ducks and some other species such as the red junglefowl have males wearing a bright nuptial plumage while breeding and a drab ''eclipse plumage'' for some months afterward. The painted bunting's juveniles have two inserted moults in their first autumn, each yielding plumage like an adult female. The first starts a few days after fledging replacing the ''juvenile plumage'' with an ''auxiliary formative plumage''; the second a month o ...

Chihuahuan Raven
The Chihuahuan raven (''Corvus cryptoleucus'') is a species in the family Corvidae that is native to the United States and Mexico. Description The proportions resemble the common raven with a heavy bill, but is about the same size as a carrion crow, or slightly larger than the American crow ( long). The plumage is all-black with a rich purple-blue gloss in good light. Like the forest raven, little raven, fan-tailed raven and Australian raven, it is one of the smaller raven species. The larger species of raven are the common raven, thick-billed raven, white-necked raven and brown-necked raven, with the common and thick-billed ravens being the world's largest raven species and the little and fan-tailed ravens being the smallest. The Chihuahuan raven is similar in appearance to the Australian raven, although with dark brown irises and whiter feather bases. The nasal bristles extend further down the top of the bill than in any other '' Corvus'' species to about two-thirds the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sinaloa Crow
The Sinaloa crow (''Corvus sinaloae'') is a crow native to western Mexico. Description Visually, it is nearly identical to and the same length (34–38 cm) as the Tamaulipas crow (''Corvus imparatus''). It has the same purple-glossed, silky, black plumage with a black bill, legs, and feet. The two species differ markedly in voice. Distribution and habitat It occurs on the Pacific slope from southern Sonora south to Manzanillo. The crow inhabits coastal regions where it forages on the seashore, semi-desert, open woodlands, river banks and hills up to 300 metres or more. It is very common around coastal towns and villages. Diet Food is taken both on the ground and in trees. On the seashore it can be found turning over objects to find its food and it will take a wide range of invertebrates such as small shellfish, crabs, and insects. Fruits of many types are also taken and eggs and nestlings are also on the menu when opportunity arises. Breeding Often, this bird will nest in a th ...

Fish Crow
The fish crow (''Corvus ossifragus'') is a species of Corvus, crow associated with wetland habitats in the eastern and southeastern United States. Taxonomy and etymology The fish crow was given its Binomial nomenclature, binomial name by the Scottish Ornithology, ornithologist Alexander Wilson (ornithologist), Alexander Wilson in 1812, in the fifth volume of his ''American Ornithology''. The binomial is from Latin; ''Corvus'' means "raven", while ''ossifragus'' means "bone-breaker". It is derived from ''os'' or ''ossis'', meaning "bone", and ''frangere'', meaning "to break". The English-language common name ''fish crow'' also derives from Wilson, who ascribed the name to the crow's aquatic diet, as described to him by local fishermen. He distinguished the fish crow from John Bartram's ''great seaside crow'' by the former's diminutive size when compared to the American crow. The fish crow's taxonomic relation to other species of the ''Corvus'' genus is still poorly understood, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Superspecies
In biology, a species complex is a group of closely related organisms that are so similar in appearance and other features that the boundaries between them are often unclear. The taxa in the complex may be able to hybridize readily with each other, further blurring any distinctions. Terms that are sometimes used synonymously but have more precise meanings are cryptic species for two or more species hidden under one species name, sibling species for two (or more) species that are each other's closest relative, and species flock for a group of closely related species that live in the same habitat. As informal taxonomic ranks, species group, species aggregate, macrospecies, and superspecies are also in use. Two or more taxa that were once considered conspecific (of the same species) may later be subdivided into infraspecific taxa (taxa within a species, such as plant varieties), which may be a complex ranking but it is not a species complex. In most cases, a species complex is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
