The AGJV supports banding operations across the Arctic, from Baffin Island to Alaska. From 1989–2015, more than 1 million geese from AGJV populations were banded. AGJV banding studies have provided information about timing of migration, recovery distributions, survival rates, population sizes, and harvest rates.
Improved knowledge of goose distribution during migration and winter has led to amalgamation of several populations of geese from breeding areas that were formerly divided into smaller regional components, including midcontinent White-fronted Geese, midcontinent Cackling Geese, and midcontinent Lesser Snow Geese. Banding data have also been used to monitor changes in distribution of species like Ross’s Geese, which have greatly expanded their range eastward over the past few decades.
Scientists rely on the interest and engagement of tens of thousands of United States and Canadian citizens to collect goose-related information. A key example of this citizen science is the large volume of information provided by hunters through harvest questionnaire surveys, species composition surveys and band recoveries. Hunters “sample” the population of marked birds by reporting their band recoveries and seasonal harvests of geese, and by submitting parts (i.e., tail fans and wing tips of harvested geese) for determining the species/age/sex composition of the annual harvest.
