Siberian Grouse Falcipennis falcipennis (Hartlaub, 1855) in Bureya Nature Reserve occupies the subalpine larch forest and spruce groves, and also light larch forests. The route accounting of number of a Siberian Grouse in these ecosystems by specially developed technique showed that this look annually is numerous during the autumn period. Population density of a Siberian Grouse, average by years, during the autumn period makes 39.7 individuals/km2. Total number of a Siberian Grouse during the autumn period only in the main ecosystems of the top subbelt of a boreal forest belt of the Reserve can reach 90–100 thousand individuals. Total number and population density of a Siberian Grouse doesn't concede to these indicators Grouse, widespread in a taiga of North America: Canadian Spruce Grouse F. (Canachites) canadensis (Linnaeus, 1758) and Franklin's Grouse F. (Canachites) franklinii (Douglas, 1829). Earlier published data according to which the average annual number of a Siberian Grouse within all area of a look makes to 1 million individuals can be considered much underestimated.
