The Common Goldeneye Duck And The Role Of Nesting Boxes In Its Management In North-Central Minnesota, Leon L. Johnson

Journal of the Minnesota Academy of Science

Evaluation of use of nesting boxes of two kinds by the common goldeneye duck (Bucephala clangula americana) in a wooded area of north-central Minnesota, where these ducks are fairly abundant, shows 69 to 80 percent of the usable boxes were eventually used. Wooden boxes were better accepted than metal boxes, but the latter provided greater protection from predators. Calculations from band recoveries indicate a hunting bag of about 36 percent for birds during their first year. This is a high rate of harvest, especially since goldeneyes do not breed until their second year. After the first year, however, mortality is …

Sympatry Changes And Hybridization Incidence In Mallards And Black Ducks, Paul A. Johnsgard

Papers in Ornithology

Changes in general fall and winter distributions of Mallards and Black Ducks over the past century have resulted in markedly increased sympatric contact during pair formation between these two forms, and have been responsible for increased opportunities for hybridization. Bureau of Sport Fisheries and Wildlife records of hybrids from 34 states indicate a minimal current hybridization rate that is about 4% of the frequency expected on the basis of mating according to mathematical probabilities of chance contact. Thus, hybridization is most frequent where both forms are almost equally abundant, indicating that no reinforcement of differences reducing hybridization in the primary …
