I admit, I love eagles and enjoy a lot to photograph them. Eagles are one of the few animals beside whales I "almost" can guarantee on my wildlife and scenery photo tours. There are plenty along the British Columbia coast and often we see them fishing too.
But make no mistake, they aren't easy to photograph, at least not when you using a big telephoto and they are close to the boat. I actually tell my guests to put down the camera and enjoy the spectacular event when they are going fishing.
I mostly use my 2.8/300mm to "get them" when they full of action.
