Nesting phenology was early and the total spring population was estimated at 107,500 geese, slightly higher than last year. Biologists estimated 30,300 nests, an average clutch size over 4.0 eggs, and nest success near 81%. Good production was also observed at a smaller colony on Wrangel Island. A snow storm and cold temperatures caused some gosling mortality around the hatching period, but biologists report the gosling production outlook remained favorable.
