While leading my annual Hokkaido nature birding workshops participants and I always spot and photograph mobs of Steller’s Sea Eagles and White-tailed on the pack ice, either feeding, relaxing and sometimes participants and I see them simply pluck fish from the water with their razor sharp talons. With these two species of raptors close cousins, there is always a thin truth between the local wildlife, the White-tailed Eagle (Haliaeetus albicilla), and the seasonal migrating Steller's Sea Eagle!  But as soon as a raptor has caught a fish the truths is off, and conflicts often turn vicious especially when fresh fish is the topic.  But the white-tailed eagle the fourth largest raptor on our planet is known to hold their own agains the Steller’s sea eagle.  Haliaeetus albicilla eagles measure from 65-95cm in length with a wingspan of 170cm to 260cm or about 5ft 5 to 8ft 5 inches. It is said this raptor has the largest wingspan of any living eagle. The male and female are similar in coloring and appearance, the accurate way to tell them apart is by tarsus width and depth and bill depth, but this is next to impossible unless they are captive or captured then released with tracking devices on their legs. I usually tell them apart by their size in which females are generally about 30% heavier and about 15% greater in linear dimensions.
