Well, decided to hang around the quickly disappearing ice in the inlet where I've been seeing a few eagles before all the ice breaks up. Had a few great days the last week with about 3-8 eagles regularly visiting for about 11/2hours every day. Only have about 1 more week before the ice all disappears. The nikon d90 seems to work well as does the sigma 150-500. I also spent 2 days with my 70-200 f2.8. Really liked it when the eagles came in extra close. Here are a few close shots taken with the 70-200.
