In the cold season, the thrush often stays with human habitation, attracted by the food that people place in feeders specially installed for feeding birds.
The body length of the bird reaches 27-30 cm, weight - about 140 grams. The sexual maturity of these birds comes, after reaching a young bird of 1 year. The period of nesting and subsequent breeding - from early spring to early summer. The number of eggs in the clutch - up to 5 pieces. The duration of the incubation period is about 2 weeks. The hatchlings feed up about 20 days until they become independent and start to feed for their own food.The average duration of thrushes-deryab in terms of natural habitat does not exceed 10-11 years.

The closest related species of Thrush are the following birds: white-necked Thrush, Fieldfare, singing and black.
As mentioned above - Deriaba is the largest species of birds of the family of thrushes. The feather dress of the bird is gray, on the belly there are characteristic dark spots. When a bird is in the air, you can see its inside of the wing, having a white color. There are representatives of this species almost throughout the entire territory of Central Europe.

With the onset of spring, they return to their nesting sites.
Power Features
It has been observed that in particularly severe winters, mistyabs often appear in urban park areas, which is explained by a higher air temperature than outside the city. Also, as a rule, within the city limits there is a thinner snow cover, which makes it much easier for birds to find food on the ground.
Natural habitat
Most often the large thrush is found in Europe, with the exception of the northern regions of Scotland, Norway.
A few decades ago, the main habitat of this species of birds was forest tracts, however, their massive logging forced the birds to adapt to new living conditions. In addition to forests (mixed), thrush can be found in the surrounding forest plantations, in fairly old gardens and shrubs.
With the onset of autumn juicy are the most preferred food for birds.ripe berries of trees and shrubs, for which birds are ready to cover even fairly large distances.
Breeding features
The end of the cold season coincides with the beginning of the period of the beginning of the nesting of blackbirds, which are broken up into pairs and are looking for a suitable place to build a nest. The laying of eggs by the female is carried out in early spring (from March to April), this is because after the appearance of offspring the thrushes will be able to get enough food to feed their chicks (snails, earthworms, larvae of various insects).
As a rule, females of females are engaged in the construction and arrangement of the nest; dry vegetation and tree branches are used for construction. The finished nest is shaped like a bowl, the tray is lined with grass and moss.
Note that, although the nests of these birds are quite large in size, they are nevertheless very sloppy. As a rule, the thrushes nests are located at a sufficient height, on the branching of the branches of large trees. Often they are ravaged by birds of prey.For one season, the female carries out one laying of eggs (the maximum number is 4-5 pcs.).
Bird voice
The thrush of Lyabya begins to sing its songs with the onset of the first heat, as a rule, the bird makes short trills, sitting high on a tree. Note that the voice and the songs themselves of this species of birds a bit resemble the singing of one of their closest relatives - the blackbird, however, the rulades of the tongue are more melancholic. In flight, the thrushes also emit certain sounds that more resemble a crackling sound made by the teeth of the crest when they are carried over in chips.
Observation of the species
Many ornithologists say that it is best to observe a thrush in the middle of light forests, on small meadows or forest clearings. With the onset of autumn, this species of feathery is chosen by city parks, where the berries that have ripened on bushes and trees become their main food.

- During the nesting period, the thrushes of the mug are quite aggressive towards other birds, which is explained by the protection of their own territory and nest. These thrushes boldly rush on uninvited guests, driving them away from the nesting site (birds of prey, cats, and even humans).
- To date, the most common thrush can be found in urban park zones.
- The family of thrushes includes quite a few species of passerine birds, including such birds as the robin, nightingale, grassworm, and others. To the genus of thrushes present, inhabiting the territory of Europe, include about two dozen species of birds.

Comparison of the species with a song thrush
The size of the wing of birds of this species is somewhat larger than that of song thrushes. At the same time, in the latter, the inner part of the feather cover of the wings is yellowish, and in the stern - white.
View protection
The population of this type of songbirds as mist-thrushes of the mistlet decreases every year due to the massive deforestation of forests. For this reason, these birds are forced to adapt to the new living conditions, which is manifested in their relocation to small plantations located along the fields, old gardens and city parks.
