NT
Siberian Grouse Falcipennis falcipennis



Justification

Justification of Red List Category
This secretive species qualifies as Near Threatened because it is likely to be undergoing a moderately rapid population decline owing to hunting and logging and probably has a moderately small population.

Population justification
The global population size has not been quantified, but the species is not described as common within any part of its small range (del Hoyo et al. 1994). Brazil (2009) has estimated national population sizes at <c.100 breeding pairs in China and c.10,000-100,000 breeding pairs in Russia.

Trend justification
There are no data on population trends; however, the species is suspected to be in decline owing to hunting and habitat loss and degradation.

Distribution and population

Falcipennis falcipennis occurs in far eastern Russia, from c.120°E to the shores of the Sea of Okhotsk and Sakhalin Island, north to c.60°N and south to the lower Amur region and the Sikhote-Alin mountains, and at least formerly to the Xiao Hinggan Ling mountains in Heilongjiang, China. It has apparently been extirpated from China (Madge and McGowen 2002). It occurs at low densities of between six and 25 birds per 100 km2 within this relatively small range, although these densities may be under-estimated because of its elusive behaviour.

Ecology

It inhabits coniferous forest, mainly of spruce, e.g. Picea jezoensis and fir Abies nephrolepis, and although it uses secondary forest, it avoids open areas and the youngest stages of forest succession.

Threats

It is assumed to be declining because of large-scale clear-cutting for timber, forest fires and hunting for food, and has been reported to disappear rapidly from colonised areas, apparently because it does not fear man and is therefore easily shot.

Conservation actions

Conservation Actions Underway
None is known.

Conservation Actions Proposed
Survey to assess the population size. Protect large areas of primary forest within its range. Quantify the extent of logging within its range. Quantify the impact of hunting on populations. Protect the species against hunting.
