This was the first time in ten years. Likely migration path This year was close to Commander "- said RIA Novosti party year-round in the Commander Islands expedition Sciences to study animals of the Red Book of Russia Yevgeny Mamaev.
As explained by the coordinator of the "gray whale" of the Institute of Ecology and Evolution of Severtsov name (IEEP) Gregory Tsidulko, increasing the number of humpback whales could be due to any climate change: temperature, flow direction.
"Humpbacks often change their route, trying to get food: krill and small fish. Apparently, this year off the coast of the Commander was more food than usual, but the reasons can be called only after analyzing the observations," — said Tsidulko.
