I pulled into a parking lot by the Merrimack River in Hooksett, NH looking for Eagles in the trees and ducks in the water. I was nearing the end with no luck sighted, when just over a snowbank, I spotted a BAEA that was quite close... I'd say 30-40 feet. Unfortunately it was almost totally concealed by the many trees between us. I backed up... moved forward... then back again... until I found a clear shot thru the tree branches of the birds head.
