Watch a Steller's sea eagle fight a golden eagle for food on Russia's Kamchatka peninsula

Russia’s Kamchatka peninsula in winter - eagles congregate near the few open bodies of water. They are all after the same thing, fish. The striking Steller’s sea eagles have the advantage of size over the smaller golden eagles. But this does not prevent the two rivals locking claws. A golden eagle has taken on a young Steller’s sea eagle in similar brown plumage. The smaller eagle shows little sign of giving in and suddenly the tables are turned.

The battle is over, but both have ended up losers. The fish they were quarreling over has long since gone. Another has made off with the prize. Kamchatka is encased in ice for 6 months of the year. Only a few eagles remain here all winter, most fly south to the islands of Japan. But for those that stay to tough it out, the payoff will come in spring. Then they will have a head start over their migratory comrades and be the first to secure the best nest sites.
