Cuban Palm Crow
The Cuban palm crow (''Corvus minutus'') is a relatively small corvid that is endemic to the Caribbean island of Cuba. Taxonomy The Cuban palm crow was formally described in 1852 under the binomial name ''Corvus minutus'' by the German born ornithologist Juan Gundlach. The species is monotypic: no subspecies are recognised. The Cuban palm crow was formerly treated as a subspecies of the Hispaniolan palm crow (''Corvus palmarum''). sympatric fish crow ''C. ossifragus''East Coast of the United StatesTamaulipas crow ''C. imparatus''Sinaloa crow ''C. sinaloae''Mexico''Corvus leucognaphalus''Jamaican crow ''Corvus jamaicensis''This indicates two distinct arrivals of crows onto the island of Cuba (with the ancestor of the two palm crows being a later arrival), and a resulting niche differentiation, similar to ''C. leucognaphalus'' and ''C. palmarum'' on Hispaniola Hispaniola (, also ) is an island between Geography of Cuba, Cuba and Geography of Puerto Rico, Puerto Rico in the ...

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] |
Birds Described In 1852
Birds are a group of warm-blooded vertebrates constituting the class (biology), class Aves (), characterised by feathers, toothless beaked jaws, the Oviparity, laying of Eggshell, hard-shelled eggs, a high Metabolism, metabolic rate, a four-chambered heart, and a strong yet lightweight Bird skeleton, skeleton. Birds live worldwide and range in size from the bee hummingbird to the common ostrich. There are over 11,000 living species and they are split into 44 Order (biology), orders. More than half are passerine or "perching" birds. Birds have Bird wing, wings whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the Flightless bird, loss of flight in some birds, including ratites, penguins, and diverse endemism, endemic island species. The digestive and respiratory systems of birds are also uniquely a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Niche Differentiation
In ecology, a niche is the match of a species to a specific environmental condition. Three variants of ecological niche are described by It describes how an organism or population responds to the distribution of resources and competitors (for example, by growing when resources are abundant, and when predators, parasites and pathogens are scarce) and how it in turn alters those same factors (for example, limiting access to resources by other organisms, acting as a food source for predators and a consumer of prey). "The type and number of variables comprising the dimensions of an environmental niche vary from one species to another ndthe relative importance of particular environmental variables for a species may vary according to the geographic and biotic contexts". See also Chapter 2: Concepts of niches, pp. 7 ''ff'' A Grinnellian niche is determined by the habitat in which a species lives and its accompanying behavioral adaptations. An Eltonian niche emphasizes that a specie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jamaican Crow
The Jamaican crow (''Corvus jamaicensis'') is a comparatively small corvid (35–38 cm in length). It shares several key morphological features with two other West Indian species, the Cuban crow (''Corvus nasicus'') and the white-necked crow (''Corvus leucognaphalus'') of Hispaniola, which are very closely related to it. Taxonomy The Jamaican crow, under the name "chattering crow", was described by the English naturalists John Ray in 1713 and Hans Sloane in 1725. The Irish physician Patrick Browne used the name "gabbling crow" for the species in 1756. In France the naturalists Mathurin Jacques Brisson in 1760 and Comte de Buffon both used the name "La corneille de la Jamaique". A binomial name was not introduced until 1788 when the German naturalist Johann Friedrich Gmelin revised and expanded Carl Linnaeus's ''Systema Naturae'' and coined the binomial name ''Corvus jamaicensis''. The species is monotypic: no subspecies are recognised. Description The overall appearance i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White-necked Crow
The white-necked crow (''Corvus leucognaphalus'') is the largest of the four Caribbean corvids. It is endemic to the island of Hispaniola (split between Haiti and the Dominican Republic); it was formerly also extant on Puerto Rico and Saint Croix in the United States Virgin Islands, but has been extirpated from both islands due to considerable forest clearance and hunting for meat. Taxonomy Two other species, the Cuban crow (''C. nasicus'') and the Jamaican crow (''C. jamaicensis''), appear to be very closely related to it, sharing several key morphological features. The ancestor of the fourth and fifth species from this region, the Hispaniolan (''C. palmarum'') and Cuban palm crows (''C. minutus''), would appear to be a later arrival (at least in evolutionary terms); both species show more similarities to the fish crow (''C. ossifragus'') of mainland North America and two Mexican species. This is despite ''C. palmarum'' being sympatric with the white-necked crow on Hispaniola, ... [...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 ...

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] |
