Scientists have discovered that at least some of these sea lions bridge the supposed new Cold War between Russia and America by migrating to the waters of Bristol Bay in Alaska from their rookery in Matykil Island, off Russia's Sea of Okhotsk coastline. 

The cameras observing the life of sea lions on this remote island were installed in 2013

Project manager Vladimir Burkanov said: 'In two years, a joint project between the WWF and Magadan Reserve creating an autonomous system of monitoring sea lions has brought very good results. Thanks to the cameras, we can conduct year-round monitoring of one of the most difficult rookeries in the region.'

Scientists began visiting this rookery in 1983, when Magadan Reserve was established. The Yam islands are in a dangerous area for shipping and there are constant rock falls on Matykil. 

On this rookery live 800 - 1000 of adults, and  470 or so sea lion cubs are born annually. 

Scientists have found that animals perform migration between all the rookeries of the Okhotsk Sea, including Matykil, despite its remoteness. 

Last year a tagged sea lion from Matykil was spotted at Cape Nevenhem in Alaska, in the waters of Bristol Bay. 

So the animal set a kind of record, passing no less than 4,000 kilometres from its native breeding grounds.
