Migration and Habitat Use of Pacific Barrow's Goldeneye

Connectivity among annual cycle stages, rates of site fidelity, and the geographic scale of dispersal are largely unknown for Pacific Barrow’s Goldeneye (BAGO). This precludes managers and researchers from identifying demographically discrete units for population management, and for understanding the scale of inference from field studies. Further, habitats and specific sites that may be particularly important for BAGO are difficult to identify, as this species is not well covered by surveys for most of its annual cycle and range.

Sea Duck Research at the Centre for Wildlife Ecology

The Centre for Wildlife Ecology has several studies underway that address conservation issues affecting sea ducks along the Pacific coast. The issues, species, and populations being studied are shared concerns of the Centre for Wildlife Ecology, the Canadian Wildlife Service, and agency and academic collaborators throughout North America.

Sex-biased winter philopatry in Harlequin Ducks: are waterfowl really an exception to the rule?

Many birds species exhibit a resource based mating system where males defend breeding territories. This mating system is thought to have lead to male-biased philopatry as male birds are better able to defend familiar territories. In contrast, female waterfowl are more likely than males to return to their breeding grounds. Waterfowl are the exception because males cannot economically defend breeding territories and a mate-defense system has evolved. However, waterfowl pair in the winter.
