The darker the color, the more favorable the climate conditions are for survival. The outlined areas represent approximate current range for each season. More on reading these maps.
This species is famous for vomiting a foul, sticky oil at predators when confronted at the nest, which is on a high cliff overlooking either the Atlantic or Pacific ocean in the far north. As a member of the tubenose family, the Northern Fulmar is, when not nesting, almost completely pelagic—that is, it spends almost all of its life at sea—often hundreds of miles from the nearest point of land. Christmas Bird Counters are viewing these birds from the Pacific Coast, which is why Audubon's climate model can project a 67 percent loss of current winter range in these areas. More data may help provide clues as to whether future counters will be able to see them from the coast in the future.
