I am taking a cruise from New York to Newfoundland, Greenland, Iceland, Norway, and then to London. Is there a field guide that addresses the seabirds and/or shorebirds of the North Atlantic? I haven't been able to find what I'm looking for. I don't want to be burdened with 4 or 5 different field guides especially since this won't be a birding specific vacation. Any assitance would be appreciated.
