Abstract: The 27th consecutive spring aerial emperor goose survey was conducted from 24-29 April. Adverse weather precluded surveying segments 64-82 and 125-137 so we expanded our count by using the previous 3-year average for segments not flown in 2007. A total of 77,541 emperor geese were estimate...

| Summary: | Abstract: The 27th consecutive spring aerial emperor goose survey was conducted from 24-29 April. Adverse weather precluded surveying segments 64-82 and 125-137 so we expanded our count by using the previous 3-year average for segments not flown in 2007. A total of 77,541 emperor geese were estimated (up 1.9 % from 2006 and up 21.8 % from the 1981-2006 year average) in coastline and estuarine habitats from Jacksmith Bay to central Izembek Lagoon, including all the north side of the Alaska Peninsula and the south side east to Kuiukta Bay. The 3-year average of consecutive spring surveys is now 69,205 birds (up 17.0 % from the previous 3-yr average of 59,142). Other species of emphasis included Pacific brant and Steller’s eider with observed populations of 47,572 and 14,439, respectively.
