Perspective of future monitoring of the population


If the main our objective is to find the real and working method to control eagle population, we have to run new strategy of our researches.
I support the idea to organise the long-term all year round investigations of the factors limiting SSE surviving. It must be new level of investigation, comprehensive and complexly.

The following acts I am consider as the high-priority for future monitoring of SSE population at Kamchatka:

First, It is impossible to grasp immense, Kamchatka is too large to cover all the territory by helicopter surveys both at winter and summer. So, we have to use the model research base station for long-term research. The Kronotskiy Reserve territory looks the best for this goal, first of all, because of there is population which is under control during last 20 years here and we have the detail information about the life of more then 60 nests. Also, it is good known area with developed research station and wide net of local cabins. Also, at this territory a long term research of Pacific salmon are made by Salmon Institution.

What kinds of reserach this project must include:

  1. Detail research of SSE life cycle and relationships with the main prey life cycles;
  2. Detail research the living requirements for the habitats, nests, hunting range (I gess, it is almost clear for us);
  3. Understanding the eagle's living strategy (I mean first of all the enigmatical notunderstandable winter distribution.
I gess, that the most important for SSE population at Kamchatka at the present monitoring would be the following:
1. The new global winter airsurveys.
2. Mass marking of eaglets.
3. Marking the adult birds on wintering sites both at Kamchatka and Japan.
4. I am not support the idea to continue summer airsurvey.
