Corvus corax
Common Raven

Description

Distinguishing Features - Completely black with purplish or violet reflections, most pronounced on back wings and tail. Male and female indistinguishable but female is slightly smaller.

American Crow Size - 56 - 67 cm (22.5 - 26.75 in).

Habitat

Widespread; prefers wide open spaces for foraging and woodlots for nesting; anywhere with an easily accessed supply of food. Built-up rural areas, roadsides and fields are their favourite habitat, as are garbage dumps.

Nesting

Generally in cavities of trees; sometimes on cliff ledges. The large nest is made of twigs, lined with any number of available soft materials, such as grass, moss, leaves or hair. Eggs, 3 - 4; greenish, spotted randomly with brown blotches. Incubation period 20 - 21 days.

Notes

The Common Raven is often mistaken for the American Crow but is much larger and sports a much larger bill. The Raven's call lends the best distinction between it and the Crow. It is a hoarse croak or Kwawk.

Like its cousin, the Crow, it is omniverous and will eat practically anything.
