Mergansers in Flight

I was on top a 70 foot bank overlooking Puget Sound when I noticed a flock of birds flying by off-shore. I took a shot, not knowing what kind of bird they were … too far away for my visual identification skills. Nice to have the resolution to crop in and do the identification.
