Spacing Patterns, Mating systems, and winter Philopatry in Harlequin ducks. 

Gregory, J.R.; Cooke, F.; Goudie, R.I.; Boyd, W.S. (University of California Press, 2000)
Many species of waterfowl form pair bonds during the nonbreeding season, yet current descriptions of mating systems and patterns of philopatry in waterfowl focus on the breeding grounds. We studied wintering Harlequin Ducks ...

Molt and the basic plumage of male Harlequin Ducks. 

Cooke, F; Robertson, G.J.; Goudie, R.I.; Boyd, W.S. (University of California Press, 1997-02)
Using observations on 28 individually marked male Harlequin Ducks from mid-June until late November, we describe plumage changes which occur as individuals proceed from the alternate plumage through basic to the return of ...

The Timing of Pair Formation in Harlequin Ducks. 

Robertson, G.J.; Cooke, F.; Goudie, R.I.; Boyd, W.S. (University of California Press, 1998-08)
The timing of pair formation varies within and among species of ducks. In this study we documented the chronology of pair formation in a population of wintering Harlequin Ducks (Histrionicus histrionicus) in southwestern ...

Site fidelity of Black Brant wintering and spring staging in the Strait of Georgia, British Columbia. 

Reed, E.; Cooch, E.G.; Goudie, R.I.; Cooke, F. (University of California Press, 1998-08)
Site fidelity has important implications for population genetics and dynamics. In birds, most studies have dealt with breeding ground fidelity, ignoring the fact that waterfowl mainly pair in winter or early spring. We ...

Survival, emigration and winter population structure of Harlequin Ducks. 

Cooke, F.; Robertson, G.J.; Smith, C.M.; Goudie, R.I.; Boyd, W.S. (University of California Press, 2000-02)
A population of individually marked Harlequin Ducks (Histrionicus histrionicus) at White Rock, British Columbia, Canada was examined to measure the degree of population differentiation among birds which pair during the ...

Long-term pair bonds in Harlequin Ducks. 

Smith, C.M.; Cooke, F.; Robertson, G.J.; Goudie, R.I.; Boyd, W.S. (University of California Press, 2000-02)
We documented the frequency of pair reunion in Harlequin Ducks (Histrionicus histrionicus) on breeding streams in Alberta, and at a molting/wintering area in southwestern British Columbia. As long as their mate is alive, ...
