Winter status The last more or less representative winter survey was conducted at 1986, 13 years ago. Since this survey we northing know any news about winter distribution and status af SSE in peninsula. This survey covered just 5 percent of territory potentionally attractable for eagles. |

Main part of winter allocation of SSE is assembled in area
of Kuril lake, where annually concentrates about 500 birds.
It is characteristically, that this probably biggest SSE
concentration
in the world was opened only in 1985, though the first
information
about it are available in the beginning of this century!
Summarise, we northing know about status and the character
of residence in winter of other then 2,5-3 thousand birds.
Meanwhile, some facts can intrigue us. So, it is known, that in winter SSE forms temporary, fast breaking up aggregations in a local spots of temporary appearance of a plentyful forage, for example, winter spowning of smelt or Salmo salvelinus. These temporary agregations break up as fast, as well as arised, but can include up to 200-300 individuals. Where are these thousand birds arised from, how they find out the appearance of new food locations and where they disappearing after food source run down is an enigma for us. The absence of the information of winter eagles' allocation is extremely alarm fact, the main blank spot in our knowlege of the SSE ecology. |
