Habits of American Crow mating, feeding, and nesting detailed

American Crow Habits

american crow

Almost every bird watching guide describes the American Crow as one of the most intelligent birds. Other adjectives used are resourceful and mischievous. Any way you describe them, these birds are worth watching as they go about their nesting and feeding habits.

One habit of these birds is called "mobbing". When you hear them giving harsh, drawn-out caws and see them diving into tree tops, chances are, there is a hawk or owl in the tree.

Even if the predator bird leaves the area,

the crows will chase after the owl or hawk for a while.

One speculation for this behavior is that it may be an effort to teach young crows who their predators are.

Although there is no proof that this is the reason.

Description

The American Crow is 17 to 21 inches in length. All black with a fan-shaped tail. Both male and female are similar in apperance. This birds voice is the best way to distinguish it from other all black birds.

The voice is a long, descending "caaaw". Although it has a variety of other calls which are important to their system of communication.

the ground. The male has a courtship display of facing the female and fluffing its body feathers.

Then he partially spreads his wings and tail and proceeds to bow repeatedly while uttering a brief rattling song.

Once a male and female have mated, they perch together and may touch bills and preen each other's feathers.

This behavior may not be seen, as they mate for life. Pairs already mated do not usually have courtship displays. Pairs that are unsuccessful at breeding may return to their families.

Should a mate die, the surviving mate will attempt to find a new mate at sometime.

Crows also demonstrate cooperative breeding. This is when the previous years young help raise the newest brood. It's not unusual for males to wait a few years before mating.

Nesting Habits

The American Crow is secretive around its nest. While noise is a mainstay of its behavior in other areas, the nesting site is quiet.

Sometimes difficult to find, the nest is placed 18 to 60 feet above ground in a tree near the trunk. Made of twigs, sticks, lined with bark, grass and moss. The nest is about 12 inches in diameter.

The female lays 3 to 7 eggs that are bluish green with brown marks. Incubation is primarily done by the female with the male close by and sometimes feeding her. Incubation last about 18 days.

The young are born blind and flesh colored. After about five days, their eyes open for the first time.

Both parents feed the young, receiving help from previous years young. At five weeks of age the fledglings will leave the nest. The parents will continue feeding them for a while after leaving the nest.

Crows have one brood a year. If nesting is interrupted, they may attempt to re-nest.

Feeding Habits

The diet of these birds consist of insects, small reptiles, eggs and nestlings of other birds. They also eat carrion, fruit, and crops such as corn.

These birds are the most wary while feeding. Feeding in flocks of 5 to 7 birds, they will arrive on their feeding territory landing in the trees. While most will begin feeding on

the ground, one or more will remain in the trees watching for predators.

Cracked corn and sunflower seeds will attract these birds, although just about any kind of seed will be eaten by them.

Interesting Crow Fact

In fall and winter these birds roost in large flocks numbering in the thousands. Each day in late afternoon, the birds begin flying along fixed routes to pre-roost sites, gathering with other flocks and moving to the final roost.

Crows may fly as far as 50 miles each day to join the roost. Once there, they quiet down and wait for dawn to fly back to their feeding territories.
