In every possible opportunity we can see crows around us. These birds migrate enough, it comes from the same family as blackbirds, Raven, Magpie, Jay and also Rook and Jackdaws Europe. Raven usual in America is about 18 inches long with a wingspan of more than three meters.
Crows usually eat eggs, chicks, birds and other grains. However, they also eat harmful insects and rodents. In winter some eight thousand or more gather communal roosts at night. A crow can be easily tamed and taught to mimic some human voice. They husky 'not' quite familiar to us all that hard and usually hard, but characteristic. Geographically, the crows are found on every continent in the world except South America and Antarctica.
The crow bird is
huge, most commonly the black bird of the family of Corvidae and the Genus
Corvus, which also includes the Raven. Among the most clever and cautious of
birds, they are also very adaptable in nature. The crow bird may also sometimes turn out to be a huge cause of nuisance when they all collect in enormous communal roosts. Many times
over, they can number from hundreds to even thousands in the same area, and
this flock of crow birds is
called “murder”. They are omnivorous and highly aggressive in nature. They prey
on other birds as well as their eggs and are quite often very destructive to
crops.
On the other hand they are beneficial and advantageous in
helping to control the environment from insects and small rodents.
Although the crow
bird is territorial in the breeding season, they are also gregarious
sometimes. Even when the breeding season arises, they gather together to mob
owls and other predators. Crows in turn maybe thronged by other birds, as their
omnivorous diet includes eggs and nestlings as well as other smaller animals,
vegetable matter, carrion and garbage. Crow nests are huge platforms of sticks
that are usually built in tall tree. Their three to sometimes eight eggs are
deeply coloured and are incubated by the female. The young ones are nurtured by
both the parents.
All of the North American crows are deep black in colour,
with more or less of a glossy sheen, but numerous species from elsewhere ate
conspicuously marked with white or grey. The American crow bird is also known as the Common Crow, as it is a bird that
most people come around to seeing everyday.
The crow bird
does not usually get along with other birds of prey, such as hawks, owls and
eagles. They will mostly gather together to mob these birds if they can. Mobbing
calls for diving, bombing, chasing and even harassing.
Therefore, the crow bird is very intelligent but many times over they are
scorned, hated or ignored by birders. They are accused of robbing nests of the
young songbirds, scaring away other birds, being too loud with their “caws”
etc. Nevertheless, the crow bird
form strong family units by assisting one another even during nesting, while
foraging for food, one crow may stand guard as a lookout while the others feed
and lastly the crow bird is
extremely adaptable, learning to live in a variety of habitats, even with
mankind.
