One of, if not the main reason for professional wildlife photographers visiting Chilkat this time of year is the opportunity to shoot the eagles fighting. The behavior is fascinating to watch while extremely frustrating to photograph. One often waits quite some time for action that only lasts for a few seconds. And there are no re-does.
Why the birds fight at all is an interesting question. There are PLENTY of fish for all the birds. But it is very common to see birds fighting over scraps with whole, living fish beached in the shallows just a few feet away. So the conflict between the birds seems to be driven by dominance behavior rather than by a struggle for resources. Also if one is observant, the birds seem to recognize one another or at least they are very skilled at reading one another's body language. Quite often birds will surrender a fish that they eating with no attempt to defend it. At other times they will fight viciously. Also many times a bird will dive towards a grounded bird only to flare off at the last second. I call those high speed fly-byes. Also very frustrating because it's nearly impossible to get both birds in the frame together much less both in focus.
At any rate, here are a few shots.
1) As deadly as this looks it's going to be, the grounded bird dodged at the last second, surrendering its claim.
2) Same situation as above. No harm done.

3) This looks like a series shot but is three birds. They were amicably sharing a fish when all of a sudden a fight errupted. With much squawking and flapping one grabbed the remaining scraps and all three flew away.
4) Now this fight was no joke. Note the talons of one of the upper birds dug into the breast of another.
5) And another flyby shot. Whether it intended to do so from the beginning, the juvenile bird flew on by when the grounded bird went completely inverted to present its talons. This is the type of shot that we're hoping for. Though getting such a shot with both mature birds would be much preferred
