a common raven.

The raven has been the object of countless myths and legends around the world.
Odin, the supreme deity of Norse mythology, sent out a pair of ravens at sunrise
every day, and at noon they would return to perch on his shoulders and tell him
what they had learned. Ravens were sent to sustain the prophet Elijah in the desert,
and Native American peoples in the Pacific Northwest considered Raven to be the
god who brought life and order. He was also a trickster and succeeded in stealing
light from the power who wanted to keep the world in darkness. The raven has also
appeared in plays by William Shakespeare and in Edgar Allan Poe's most famous
poem.
Ravens belong to a family of birds known as "corvids" that includes jays,
crows and magpies. Corvids are the largest of all the perching birds and are known
for their harsh voices, aggressive behavior and powerful, all-purpose beaks. Two
raven species inhabit North America--the common raven and the Chihuahuan raven.
Both are found in Texas.
Young common ravens beg for food.
The common raven ranges around the globe in the Northern Hemisphere and few,
if any, birds are less influenced by climate and altitude. Ravens inhabit a wide
array of habitats-- from the Arctic tundra to Central America and from the tops
of the highest mountains to parched deserts and rocky shores. In Texas the common
raven is a year-round resident of the Trans-Pecos and the western edge of the
Edward's Plateau. Its cousin, the Chihuahuan raven, inhabits the arid Southwest
southward into central Mexico. It resides in the western half of the state--from
the Panhandle to the Edward's Plateau and southward along the Rio Grande to Brownsville.
It is smaller than the common raven, has a higher pitched call, and white feathers
at the base of its neck that can be seen only when the feathers are ruffled--thus
an earlier name: the white-necked raven.
The common raven is voracious, belligerent and amazingly intelligent. More
than two feet in length, it is much larger and bulkier than the crow and has a
longer, heavier bill. Its all-black feathers have a purplish-blue iridescence
and are loose and shaggy around the neck. Its beak and legs are also black and
its tail is wedge-shaped. Because crows and ravens are competitors, they generally
are not found in the same habitats. The Chihuahuan raven replaces the crow in
the desert southwest.
Ravens build their large stick nests in trees, on utility poles and on rocky
ledges and cliffs. They feed primarily on carrion, but also eats insects, seeds,
fruits, eggs, nestlings and small animals. In the air, the raven is capable of
awesome displays of aerial gymnastics and can be distinguished from hawks by its
wedge-shaped tail. It is not uncommon to see large flocks of ravens foraging for
food, especially during fall and winter.
Look for the common raven in the Trans-Pecos region of the state. Ravens sighted
in the Panhandle, the eastern Edward's Plateau and South Texas will most likely
be the Chihuahuan raven.

| More Facts...
Ravens are largely non-migratory and can survive in some of the most extreme
habitats.
The female lays 3 to 7 greenish colored eggs that are spotted with brown.
They incubate for 18 to 21 days and the young fledge in 38 to 44 days.
The raven's most common vocalization is a low-pitched, drawn-out croak--a
raspy cr-r-rock or prruk, quite unlike the caw of a crow. The Chihuahuan
raven's call is pitched slightly higher.
"Take thy beak from out my heart, and take thy form from off my door!"
Quoth the Raven, "Nevermore." The Raven. Edgar Allan Poe, 1845.
