Corvus Research Paper

The most important factor in identifying a raven, whether a common one or one of a similar degree is that of knowing the difference between a raven and that of a crow. The raven, in this case the species of corvus corax is of the kingdom Animalia, the phylum Chordata, the class Aves, the order Passeriformes, the family Corvidae, and the genus Corvus. For a sense of comparison to the origins of both birds, by taking the American Crow (Corvus brachyrhynchos)as an example it can be found in the Nearctic region over North America along with the southern areas of Canada (Allaboutbirds.org, Similar Species). The Corvus brachyrhnchos is of the same scientific classification as it's a part of the family Corvidae, which include crows, ravens, jays,
Ravens have more of a guttural, low-croaking call and crows give a cawing sound. An auxiliary way for contrast is that ravens are more capable to make variations in sound repertoire that might sound very odd to listeners (JuneauAlaskaVideo). The last unlikeness is the raven has a longer wingspan with four thin, long feather "fingers" to the American Crow's five broad ones.
The common raven has its fair share of various habitats to roam and with those locations comes their staple of diet. This species of bird along with its subspecies are one of the most adaptable types of birds in the world given its presence on so many continents and land masses. After the bird migrated to North America a couple million years ago it therefore spawned various types of subspecies throughout the continent such as the Chihuahuan raven in the south. Thus the corvus corax zoogeography is native to the Nearctic (North America as far south as Mexico) and the Palearctic (comprising Eurasia north of the Himalayas, North Africa, and the temperate part of the Arabian peninsula) (Espinosa). These two large regions have similar fauna and thus the climate conditions made it suitable for the common raven to
Other places the common raven has been and or was found are: Australia, Hawaii, Greenland, the Canary Islands, and others. "Common ravens prefer open landscapes and most other habitats except rainforests," (Espinosa). These aerial windbreakers can be found in temperate and terrestrial habitats. The land biomes they live in includes: the tundra; taiga; desert or dune, grassland or savanna; forests and scrub
