Whales are an endangered species. Since all whale watchers are 'guests' visiting the natural environment of these animals, we consider every whale watch a true expedition rather than a sightseeing excursion. Thus, your whale watch boarding pass is not an admission to a show, but rather an opportunity to observe wild animals which, on a world wide basis, are quite rare. Whether we sight these marvelous creatures is entirely up to the whales; the probability is quite excellent--we have a 99% sighting record. On the rare occasion that we do not sight any marine mammals, a free pass will be issued. We are very fortunate to be located central to Jeffreys Ledge where cold, nutrient-rich waters support a large variety of sea life, including zooplankton, krill, sand lance, herring and mackerel, all of which are favorite foods for the whales. During the past several years, Jeffreys has hosted the largest population of whales on the New England coast. Jeffereys Ledge attracts a large variety of marine mammals. On our expeditions we have a chance of encountering 40 ton Humpback Whales, 70 ft. Finback Whales, Minke Whales and highly endangered Right Whales. Other species sighted include Atlantic White Sided Dolphins, Harbor Porpoises, Pilot Whales, Harbor Seals, Sharks, Tuna and Ocean Sunfish. For those who may enjoy bird watching, we often encounter pelagic birds such as Wilson's Storm Petrels, Greater and Sooty Shearwaters, Gannets, Fulmars, Terns and many other species (Bird species info coming soon.)
