Corvus Imparatus
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 o ...

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, there can be different colour morphs. The placement of feathers on a bird is not haphazard, but rather emerge 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 or ...

Chihuahuan Raven
The Chihuahuan raven (''Corvus cryptoleucus'') is a species of crow 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 farther down the top of the bill than in any other ''Corvus'' species to about two-thirds the l ...

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 t ...

Fish Crow
The fish crow (''Corvus ossifragus'') is a species of crow associated with wetland habitats in the eastern and southeastern United States. Taxonomy and etymology The fish crow was given its binomial name by the Scottish 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, but DNA sequencing indicates that it is most closely related to the pal ...

American Crow
The American crow (''Corvus brachyrhynchos'') is a large passerine bird species of the family Corvidae. It is a common bird found throughout much of North America. American crows are the New World counterpart to the carrion crow of Europe and the hooded crow of Eurasia; they all occupy the same ecological niche. Although the American crow and the hooded crow are very similar in size, structure and behavior, their calls and visual appearance are different. From beak to tail, an American crow measures , almost half of which is tail. Mass varies from about , with males tending to be larger than females. Plumage is all black, with iridescent feathers. It looks much like other all-black corvids. They are very intelligent, and adaptable to human environments. The most usual call is '. They can be distinguished from the common raven (''C. corax'') because American crows are smaller and the beak is slightly less pronounced; from the fish crow (''C. ossifragus'') because American ...
