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.
Spotting a Pomarine Jaeger gets the adrenaline going! Most birders see the species on offshore boat trips from spring through fall, but “Poms” are present in low numbers in the winter. Audubon's climate model suggests that the opportunity for winter sightings will diminish considerably in the decades ahead, with areas of suitable climate space falling by 96 percent. The occurrence of jaegers and most other seabirds is importantly determined by sea surface temperature (a strong proxy for food availability and an ocean feature already known to be affected by climate change). Pomarine Jaegers, with their strong powers of dispersal, may be able to mediate climatic shifts more easily than some other seabird species.
