Birds are pests. Decoy.

Wherever there are trees - in the forest, in the towns, in the cities - you can meet the gray crow. Even without seeing, you can recognize her by the familiar croaking. But it is unlikely that many people know that in the spring during the mating season, the crow sometimes sings. Her song consists of gentle gurgling sounds. For nesting crow selects groves, forest edges, parks and gardens. The nest is built by male and female from rods and small branches, lined with a relatively soft material: tow, rags, paper, feathers. Only the female incubates the eggs, it is the responsibility of the male to feed the female and guard the nest. Chicks are fed by both parents.

Crow is sedentary, sometimes roams. In winter, crows from the north migrate to central Russia, and the crows of the middle zone fly off to the south. The crow is omnivorous; it eats all plant and animal food, including carrion; in the spring during the flood it collects dead fish. It also feeds on mollusks, and it takes a shell out of the water and breaks it against a tree or throws it from a height onto a stone so that it breaks.

The crow is one of the main robbers among feathered birds. Along the banks of rivers and swamps, it scares spring from nesting birds' nests and drags eggs even in such large birds as ducks, and in the absence of nest owners - in swans. Crow destroys and chicks. If a captured chick is large (egret, cormorant chicks), the crow drops it on the ground.

In the young and middle-aged deciduous forests, you are often greeted by a chaff of forty. Her appearance is familiar to all from the drawings of children's fairy tales. A forty charm, like a jay cry, warns forest dwellers about danger.

Magpie is a good builder. The nest in it is spherical in shape, made of twigs, with a roof and a side entrance, covered with clay from the inside. It feeds forty most diverse food: insects, small rodents, eggs and chicks of small songbirds. In the nest of magpies you can often see a piece of colored glass, a button or some other object, but always shiny in the sun. A tame magpie, like a starling, can imitate human speech.
