The 2015 trends in duck breeding Populations report released by the U.S. Fish and Wildlife Service (USFWS) indicates another strong year for waterfowl populations. The report is based on surveys conducted in May and early June by USFWS, Canadian Wildlife Service, and several state agency biologists. Overall duck numbers in the survey area are statistically similar to last year and remain high. Total populations were estimated at 49.5 million breeding ducks in the surveyed area. This estimate represents an 1 percent increase from last year’s estimate of 49.2 million birds, and is 43 percent higher than the 1955-2014 long-term average.
