Justification
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence 30% decline over ten years or three generations). The population size may be moderately small to large, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

 
Distribution and population

The species has its strongholds in Norway andRussia (which together hold >55% of the European population (BirdLife International 2004), and important populations in south-west Greenland (to Denmark)SwedenPoland and Germany. Smaller numbers breed inIcelandUnited KingdomFinlandEstonia,LatviaLithuaniaBelarusAustriaCzech RepublicSlovakiaSlovenia, the former Yugoslav states, BulgariaRomania,HungaryMoldovaGreeceTurkeyIran,ArmeniaGeorgiaAzerbaijanUkraine,KazakhstanTurkmenistanMongolia, mainland China, and Japan. It formerly bred in Algeria and may still do so in Iraq.


Population justification
In Europe, the breeding population is estimated to number 5,000-6,600 breeding pairs, equating to 15,000-19,800 individuals (BirdLife International 2004). Europe forms 50-74% of the global range, so a very preliminary estimate of the global population size is 20,300-39,600 individuals, although further validation of this estimate is needed. National population estimates include: c.100-10,000 breeding pairs and c.1,000-10,000 wintering individuals in China; < c.100 breeding pairs and c.50-1,000 wintering individuals in Korea; < c.100 breeding pairs and c.1,000-10,000 wintering individuals in Japan and c.10,000-100,000 breeding pairs in Russia (Brazil 2009).

Trend justification
The population is increasing locally owing to conservation measures such as protecting eyries, providing safe (non-poisoned) food and re-introductions to certain areas such as Bavaria (Ferguson-Lees and Christie 2001).

Ecology
The species requires large and open expanses of lake, coast or river valley, within the boreal, temperate and tundra zones, nearby to undisturbed cliffs or open stands of large, old-growth trees for nesting. Its food is vertebrates (fish, mammals and especially birds), from marine, freshwater and terrestrial environments. It is mainly migratory in the north and east of its breeding range, but sedentary elsewhere.

Threats
Threats that affect this species include loss and degradation of wetlands, human disturbance and persecution, environmental pollution, collision with wind generators (Krone and Scharnweber 2003), and indiscriminate use of poisons. Modern forestry methods reduce the availability of suitable nesting habitat. Although some losses may be taking place in Asian Russia owing to increased logging and oil industry development, these are outweighed by increases in Europe.

Conservation actions underway
CITES Appendix I and II. CMS Appendix I and II.
