Migration tracks for adult Snow Geese in the Western Arctic Population

Animated plot of migration tracks for adult Snow Geese in the Western Arctic Population

Detailed Description

Animated plot of migration tracks for adult Snow Geese in the Western Arctic Population, from Fall 2018 to Winter 2019. Each colored dot represents an individual goose. The red polygon on the north slope of Alaska represents the 1002 area of the Arctic National Wildlife Refuge, where these geese briefly stage each fall.  Locations are derived from GPS/GSM collars that were deployed on adult Snow Geese from Wrangel Island (n=9) and the Colville River Delta (n=13) in August 2018. These GPS data are being used to better understand the factors that control the timing of spring and fall migrations, to compare the migration pathways of geese from different nesting areas, and to learn about fine-scale patterns of habitat use on their wintering grounds.
