The azure tit ( Cyanistes cyanus , Syn. : Parus cyanus ) is a bird art from the family of tits (Paridae). Several subspecies are distinguished.
description
Lasurmeisen belong to the same genus as the blue tits and look very similar to them in terms of body shape. With a length of 12 to 13 centimeters, they are only slightly larger; this size is only achieved by a slightly longer tail. Their plumage is white-blue with black eye stripes in a white head. The belly is white, as is a wide band on the wing covers. However, due to the close relationship, there are hybrids between the blue tit and the glaucous tit, which largely lack the yellow and green parts of the blue tit, but which have a blue cap ("Pleskemeise"). Males and females look alike.
The calls are typical of the tit and are similar to those of the blue tit.
distribution and habitat
The glaucous tit is a breeding bird of the central and eastern Palearctic in the boreal zone and in mountainous regions. The distribution area overlaps with that of the blue tit in some regions. Basically, the glaucous tit is a resident bird. However, there are occasional long migrations of individual small groups of individuals with an evasive character. In Central Europe, the glaucous tit is occasionally a wanderer.
The habitat of the glaucous tit are light deciduous and mixed forests . They occur east of Moscow. The Lasurmeise breed in hollows of old trees at a height of about 1.00 - 1.50 m, especially in pastures.
Breeding biology
The bird has one brood per year. The breeding season is the 2nd half of May. Eggs are laid daily up to a clutch size of 10 to 11 eggs. Breeding will probably begin after the last egg has been laid. The hen is responsible for the incubation. The incubation period is 13 to 14 days.
