Total Breeding Duck Population Estimates

In the traditional survey area, which includes strata 1–18, 20–50, and 75–77, the total duck population estimate (excluding scoters [ Melanitta spp. ], eiders [ Somateria spp. and Polysticta stelleri ], long- tailed ducks [ Clangula hyemalis ], mergansers [ Mergus spp. and Lophodytes cucullatus ], and wood ducks [ Aix sponsa ]) was 48 .4 ± 0.8 [SE] million birds. This estimate was similar to the 2015 estimate of 49.5 ± 0.8 million, and is 38% higher than the long-term average (1955–2015).
