Despite the much lauded launch of Cape May Bird Observatory’s, the most exciting thing for me on the site is the Mid-Atlantic Birding Forecast. When its updated, it provides a nice update on the potential weather conditions for movements of birds. David La Puma of woodcreeper.com is the guy who updates it and he has several years experience of looking at wind conditions and weather patterns to guesstimate flight conditions for both north and south migrations. I would recommend reading both these sites as well as Paul Lehman’s National Migration Forecast.
