Once the salmon start to run in Alaska my production of shots of eagles fishing drops to nil. So much so that I shift to shooting otters and other stuff. Before salmon run the birds have to catch multiple small fish per day to survive and raise chicks. Once the salmon run starts they can live on one fish every couple of days or so. And after the fish enter the creeks they quit fishing open water completely for the most part.
One day a couple of summers ago we were motoring along and saw an eagle diving on a fish ahead of us. When he made the grab he did a "face plant" in the water. That was a sure sign that 1)he successfully grabbed the fish, and 2)it was way too big for the bird to carry. When this happens, the bird will hang on to the fish and try what passes as swimming for an eagle and try to drag the fish to shore. Basically the bird moves its wings in a flying motion and with each "flap" of he wings it moves a few inches across the surface of the water. In this manner they kind of hump along towards shore. The water is typically 35-45F(2-7C) and eagles' feathers are not water proof like seabirds or waterfowl. So there is a real chance of the bird succumbing to hypothermia if they are too far from shore when they start.
We motored carefully closer to try to get a photo or some video of the "swimming" phenomenon (I've seen this several times but never get any imagery). We were too late to get the bird in the water but did get some shots as it dragged its fish up the bank. The fish is a coho(aka silver) salmon. Judging by the length relative to the bird, I'd say the fish weighed 5-8lb(2-4kg) or about half the weight of an adult eagle.
