Favorite Habitats
The bluefin is considered a migratory bird due to the fact that it often travels long distances. It is widely distributed in the central and southern parts of the Eurasian continent. She also lives in northern Africa, and she can also be found in Europe. For wintering, most of these birds fly to Africa. They give their preference to hot areas with a dry climate. To build nests, the blue-turret requires places with a reliable cover, and for hunting it needs areas with open space.
Representatives of this species are lovers of sandy expanses that border forest areas, or include single groups of trees. The most successful place for nesting they consider the hollow of old trees. During their nesting period, they can choose a light pine forest consisting of pine trees for settlements. A prerequisite for these birds is the presence of extensive glades or clearings formed for power lines. Deciduous forests or those of a mixed nature may also be equally attractive to them, if they are located on the banks of rivers or forest lakes.
Quite often, the blue-rooks can be found on the fringes of forests that are associated with open areas, such as fields or meadows, and maybe also drained spaces of former swamps. The bird is not whimsical to the nature of the forest. The main condition she considers the presence of trees with a hollow and the proximity to the open area, which she uses for hunting.
Given their habits, a bright bird will not go deep into the forest, because there are few that attract it. But to build a nest on a lonely tree growing by the road or in a field, less often on the outskirts of settlements, it can easily, provided that there is a hollow in this tree.
Chick hatching period
From the places of wintering, the bluefins arrive from mid-April to mid-May and settle in single pairs. In Eastern Europe, it settles exclusively in tree hollows, it often takes up a hollow yellow or green woodpecker, but prefers places in old trees of natural origin. The height of the hollow of the bird can range from 2.5 to 12 meters from the soil level.Inside, the lazy bird does not arrange for special litter; it will lay its masonry directly in the wooden dust, or use the nest of the previous owners for this.
The laying of the blue-vortex contains from 3 to 6 eggs, but more often 4 of them, the eggs are elliptical in shape and enclosed in a white shell, with a glossy coating. The approximate weight of an egg is 15 grams with a size of 36 millimeters in length and 30 millimeters in width. The bird is capable of laying one egg per day.
The nesting period of birds of this species has extended borders; fresh clutch is not difficult to detect both in mid-May and in the twentieth of June. They hatch the chicks once a season, both parents take part in hatching eggs. The incubation period lasts for 19 days. It is noteworthy that parents begin to sit on the eggs after the last egg is laid, which leads to a one-time offspring.
Diet
The main objects of hunting of this bird are large insects and their larvae, less often they are not attracted by large lizards or frogs, although sometimes a bird can even catch a mouse. Eating large quantities of large insects that are harmful to cultivated plants, it is of great benefit and deserves respect.
It is very interesting to observe when a bright bird preys on a mouse. Having taken a high observing position on a tree, the top of a pillar or power line, the blue grinder carefully peers down. Having noticed her victim, she quickly rushes down and grabs the mouse by the tail with her beak. The bird carries the caught mouse to the nearest tree and, while continuing to hold it by the tail, beats its head on a hard surface. The predator will continue this procedure until it makes sure that the mouse has returned its ends, only after that the mouse will be swallowed whole.
