This forest bird is one of numerous species of taiga. It is colored contrastly: dark-grey head, grey wings, bright red spot on the back (at the perching bird it is not visible), the bottom part of the body is white. Size of this bird is similar to usual blue rock pigeon, but the constitution is more massive, wings are short and wide. Flight is slow and non-manoeuvrable. It is connected to features of feed: in winter the bird eats needles and seeds of coniferous trees: fur-trees and pines. Because of such specific diet meat of a bird has an unpleasant resinous smell, and the body of dead bird is not decomposed a long time because pitch has properties of preservative. However, it not only does not prevent, but also helps some predators to make stocks of meat of these birds for winter. Feeding by needles of coniferous trees has one doubtless advantage: this forage always is plentiful, and competitors practically are absent - mass extinction had affected also populations of grouses (Tetraonidae), eating needles and buds. Number and variability of these birds had declined, and it had allowed pigeons to occupy their ecological niche. Feeding by such coarse forage has resulted to that the bird’s craw had became complicated by its structure (it has 3 chambers) and had displaced pectoral bone that has had an influence on bird’s abilities to fly. Some species of unicellular organisms live in the bird’s craw, capable to decompose wax, pitch and cellulose. The fledgling receives these symbionts with semidigested forage closer to the time of nest leaving (before it nestling eats special, characteristic for pigeons “craw milk”, separated in the first craw chamber of an adult bird). Excepting tree needles in summer pigeons are fed with insects, snails, berries and seeds of grasses, sometimes peck mushrooms, eating them together with larvae of insects.

This pigeon keeps by large flights numbering up to 300 birds and more. It nests by colonies on pine trees (on one tree it can number up to 50 nests), in clutch there are 2 - 4 eggs. Voice is cooing, as at usual pigeons.
