The true crows are in the genus Corvus. They are large passerine birds. All temperate continents (except South America) and several offshore and oceanic islands (including Hawai‘i) have representatives of the 40 or so members of this genus.

Crows in the genus Corvus appear to have evolved in central Asia and radiated out into North America, Africa, Europe, and Australia.

The latest evidence appears to point towards an Australasian origin for the early family (Corvidae) though the branch that would produce the modern groups such as jays, magpies and large predominantly black Corvus Crows had left Australasia and were now developing in Asia. Corvus has since re-entered Australia (relatively recently) and produced five species with one recognized sub-species.

They range in size from the relatively small pigeon-sized jackdaws (Eurasian and Daurian) to the Common Raven of the Holarctic region and Thick-billed Raven of the highlands of Ethiopia.

In literary and fanciful usage, the collective noun for a group of crows is a murder. However, in practice most people, and especially scientists, use the more generic term flock.

Raven is the common name given to several large black birds of the genus Corvus. Other birds in the same genus are the smaller crows, jackdaws, and rooks.

In much of Europe and North America, raven is used as a synonym for the widespread Common Raven, and much of the literature and culture surrounding ravens refers to that species.

Raven is a very large bird compared to a Crow, it has a shaggy look to the feathers on the neck, the beak is larger and stronger, they kill small animals, they are the smartest of the birds, they have a much wider range of voices. Ravens tend to stick to cold areas in the north with lots of forest, Crows eat corn in farmers fields.

Though both crows & ravens belong to the family Corvidae, the name "raven" is usually applied to larger corvids. Also, crows usually don't accept ravens as their own kind, treating them as they would raptors, ambushing them in groups. Ravens also tend to fly at higher altitudes than the smaller crows.

What species of Crow? Fish crow, Mexican crow or American crow?? What species of Raven? Common Raven or Chihuahuan raven?? They are all very different...

I am going to assume you want the differences between the American Crow and the Common Raven....

Audubon Society Field guide to Birds

Common Raven (Corvus Corax)

Description: 21-27" SImilar to American crow but larger, with heavier bill and wedge-shaped tail. At rest, throat appears shaggy because of long, lance-shaped feathers. Often soars like a hawk.
Voice: Deep, varied, guttural croaking; a hollow wonk-wonk.
Habitat: Coniferous forests and rocky coasts; in West, also in deserts and arid mountains.
Nesting: 4-7 dull green eggs, spotted with brown, in a large mass of sticks containing a cup lined with fur, moss and lichens, placed on a cliff or in the top of a conifer.
Range: Resident from Aleutians, northern Alaska, and northern Canada south throughout western United States and to Minnesota, Great lakes, and northern New England; in Appalachians to northwest Georgia. Also in Eurasia and North Africa.

The Common Raven is common only in wilderness areas; despite its large size and intelligence, it is very sensitive to human persecution and was long ago driven out of settled areas by shooting and poisoning. Ravens are primarily scavengers, and around towns in the North they compete with gulls for garbage. They also raid seabird colonies, consuming many eggs and young. They regularly ride on rising air currents and frequently indulge in aerial displays, with mock fighting, tumbling and other forms of acrobatics.

American Crow "Common Crow" (corvus brachyrhynchos)

Description: 17-21" A stocky black bird with stout bill and fan-shaped tail. Fish Crow smaller, slimmer and glossier; larger ravens have wedge-shaped tails.
Voice: Familiar caw-caw or caa-caa
Habitat: Woodlands, farmlands and suburban areas.
Nesting: 4-6 dull green eggs, spotted with dark brown, in a large mass of twigs and sticks lined with feathers, grass and rootlets, and placed in a tree.
Range: Breeds from British Columbia east to Newfoundland and south to southern California, Gulf Coast and Florida. Winters north to southern Canada.

Every continent except South America has at least one familiar roadside crow, and this is the species in North America. It is almost impossible to go into the countryside without seeing these birds along highways or flying overhead. Intelligent, wary, virtually omnivorous, and with a high reproductive capacity, the American Crow is undoubtedly much more numerous than it was before the arrival of settlers. Crows may gather in roosts of over half a million birds and are so abundant that even an ardent defender of birds might not deny that they are destructive to crops and should be controlled, although they consume enormous amounts of grasshoppers, cutworms, and other harmful insects.


SO the answer to your question "what is the difference between a crow and a raven?" is... size, habitat, voice, range, behaviour and nesting.

the only similarities they share aregeneral appearance, the colour of feathers and eggs, intelligence, and diet...

They're different variations of the same bird...Crows generally are larger than ravens, it just depends what region they're from.

Ravens are noticeably bigger, have different-shaped beaks, and tend to be solitary instead of congregating in groups.
