The
Common raven (Corvus corax) is any of several species of heavy-billed, dark birds, larger than crows, of the genus
Corvus, family Corvidae (q.v.). The common raven (C. corax) is the biggest passerine bird (member of the order
Passeriformes); it reaches a length of as much as 66 cm (26 inches) and has a wingspan of more than 1.3 m (4 feet).
(Some magpies and the lyrebird are bigger than the raven in length but are smaller bodied.) Although it looks like
a crow, the raven has a much heavier bill and shaggier plumage, especially around the throat. The raven's lustrous
feathers have a blue or purplish iridescence. In the white-necked raven (C. cryptoleucus) of western North America,
the base of the neck feathers are white. Other species of ravens, some with white or brown markings, occur in Africa,
southern Asia, and North America.
Formerly abundant throughout the Northern Hemisphere, the raven is now restricted to the wilder, undisturbed parts
of its range. It is among the hardiest of birds, inhabiting the northern tundra and coniferous forests as well
as barren mountains and desert. It is keen-sighted and notably wary. Long before it was immortalized in Edgar Allen
Poe's poem "The Raven," the common raven was a near-universal omen and symbol of dark prophecy -- of
death, pestilence, and disease, though its cleverness and fearless habits also won it a degree of admiration, as
evidenced in its noble heraldic roles in the mythology of some peoples.
Like other corvids, the raven is a noisy, aggressive omnivore whose diet includes rodents, insects, grain, and
birds' eggs. In winter, especially, it scavenges and feeds on carrion, dead fish, and refuse. The raven has a large
and varied vocabulary, including guttural croaks, gurglings, and a sharp metallic "tok" (which Peso has
learned to mimic all too well!) The common raven usually is solitary but may feed in small flocks. The raven's
spectacular courtship flight involves soaring and all kinds of aerial acrobatics. The birds' crudely made nest
of coarse sticks, usually lined with hair or shredded bark, is a bulky structure up to 1.5 m (5 feet) in diameter
that may be built on a cliff or the top of a large tree. The young remain in the nest for about a month. If captured
while a nestling, a raven may make an interesting pet capable of learning to mimic a few words. One captive bird
on record lived 69 years.
Mythology: The Raven is a central figure in West Coast native traditions from California to Alaska. Among his many
feats, he stole the moon and sun from the Sky Chief and put them in the sky, brought humans the first berries and
salmon, and (according to several traditions) called the first humans up from the earth, or discovered the first
human babies within a clamshell. Raven was perpetually hounded by the trickster-god, Coyote. Raven is known by
many names, including He'mask.as (Bella Bella tradition), Txamsem or We-gyet (Tsimshian), Nankil'slas (Haida),
Yehl (Tlingit), and Kwekwaxa'we (Kwakiutl).

Also
belonging to the family Corvidae (order Passeriformes), crows are smaller and less heavily billed than most ravens.
They are named for their typical call: "caw" or "crah." More than 20 of the 30 species of the
genus Corvus are known as crows, and the name has been widely borrowed.
The common crows are C. brachyrhynchos of North America and C. corone of Eurasia. The latter has two races (sometimes
considered separate species): the carrion crow (C. c. corone) of western Europe and eastern Asia and the hooded
crow (C. c. cornix), occupying the region between and occurring also in the northern British Isles. All crows are
about 50 cm (20 inches) long and are coloured glossy black; the hooded crow has touches of gray. Other species
include the house crow (C. splendens) of India to Malaysia (introduced in eastern Africa); the pied crow (C. albus),
with white nape and breast, of tropical Africa; and the fish crow (C. ossifragu) of southeastern and central North
America.
Crows are omnivorous and eat grain, berries, insects, carrion, and the eggs of other birds. The crow's habit of
eating cultivated grains has made it very unpopular with farmers, who often try to kill the birds. Crows also eat
many economically harmful insects, though. They feed chiefly on the ground, where they walk about sedately. Crows
are gregarious, and at times they roost together in great numbers (tens of thousands), but most species do not
nest in colonies. Each mating pair has its own nest of sticks and twigs, usually high up in a tree, in which are
laid five or six greenish-to-olive eggs that have darker speckles. A crow may live 13 years in the wild and more
than 20 years in captivity. Some pet crows "speak," and in the laboratory some have learned to count
to three or four and to find food in boxes marked with symbols.
