A spring waterfowl survey was conducted from 3 April to 23 May along the Naknek River of the Alaska Peninsula. This monitoring continues the series of annual surveys initiated in 1983, with the addition of comprehensive ground surveys. The purpose of these surveys was to determine species composition, abundance, phenology, and distribution and relate these variaton to human disturbances along the river and migration phenology. Overll waterfowl numbers remained relatively stable as compared to previous spring surveys, with staging peaking in late April for swans, geese, and dabbling ducks. Diving duck numbers peaked a week earlier. Numbers of geese staging on the Naknek River decreased, while dabbling ducks increased due to higher numbers of northern pintails.
