Estimating The Population Of Greater And Lesser Scaup During Winter In Off-Shore Louisiana, Sean David Kinney
Estimating The Population Of Greater And Lesser Scaup During Winter In Off-Shore Louisiana, Sean David Kinney
LSU Master's Theses
I analyzed data from an experimental aerial transect survey, using stratified random sampling, to estimate wintering populations of greater scaup (Aythya marila) and lesser scaup (Aythya affinis) (hereafter scaup) in off-shore waters along the coast of Louisiana during winters 2000-2002. My objectives were to evaluate anecdotal reports of large numbers of scaup in off-shore waters of Louisiana during winter, and to develop estimates and confidence intervals for numbers of scaup in this area. My analysis yielded estimates of 815,700, 420,600, and 791,000 scaup in off-shore Louisiana for years 2000-2002, respectively. Confidence intervals were 1,087,000 to 545,000, 594,300 to 247,000, and …
