Each year we count duck broods to index production. This survey targets Lesser Scaup and counts begin around 21 July. Up to 43 wetlands are sampled, spread among 2-4 wetland complexes. Counts are conducted on foot or from small inflatable boats. Relative to the long-term pattern, we look for decreases, no change, increases, or big increases in production across index waterbodies.
