Abstract

In winter, in Kamchatka and Northern Kuril Islands (Paramushir Island) Steller's Sea eagles regularly patrol fishing vessels near marine harbors and control their unloading process to be able to eat the discarded and injured fish, other seafood and food household wastes from the ships. They also willingly use landfills and industrial water discharges as habitats in case food wastes are present there. Besides, in Kamchatka Steller's Sea eagles use artificial structures (in particular, power transmission towers) as roost sites, can pick up animals hit by cars on the roads as prey and land on the snow-free concrete surface of the runway at the airport (Yelizovo city). This is similar to the well-known situation for the wintering conditions of Sea eagles from Japan, and the difference is that the larger portion of the local winter population of Sea eagles winters in Hokkaido under the anthropogenic conditions, and a smaller portion winters in Kamchatka.
