From: Wintering North Pacific black-legged kittiwakes balance spatial flexibility and consistency
Annual distribution of black-legged kittiwakes (Rissa tridactyla) from the Pribilof Islands during their central wintering period (October thru February). In a 2008/09 (n = 38), b 2009/10 (n = 44), and c 2010/11 (n = 33). The boundaries of the ecoregions are shown following Longhurst, 2010, with the Bering Sea [BER] and Sea of Oskhosk [OSK] separated into two subregions. Remaining abbreviations are as follows: ALSK = Alaska Coastal Downwelling Zone, CAAL = California Current, KURO = Kuroshio Current, NPPF = North Pacific Polar Front, PSAE = Eastern Subarctic Gyre, PSAW = Western Subarctic Gyre
