Is there a positive relationship between body size and fecundity in lesser snow geese?
(University of California Press, 1992)
Molt and the basic plumage of male Harlequin Ducks.
(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 ...
Site fidelity of Black Brant wintering and spring staging in the Strait of Georgia, British Columbia.
(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 ...
Age-specific costs of first-time breeding
(University of California Press, 1995)
We investigated the cost of first-time breeding in a population of Lesser Snow Geese (Anser caerulescens caerulescens) nesting at La Perouse Bay, Manitoba, Canada. We estimated local survival and capture probabilities of ...
Seasonal movements of Marbled Murrelets: evidence from banded birds.
(University of California Press, 1999-08)
Recent techniques for capturing Marbled Murrelets (Brachyramphus marmoratus) have created opportunities for studying them through systematic banding programs. One murrelet banded in breeding plumage during the summer of ...
Dominance, brood size and foraging behaviour during brood-rearing in the lesser snow goose: an experimental study.
(University of California Press, 1995-02)
We investigated the relationship between brood size and social dominance during the brood-rearing period in Lesser Snow Geese (Anser caerulescensc aerulescens) by experimentally manipulating food availability to create ...
Colonial Nesters in a Deteriorating Habitat: Site Fidelity and Colony Dynamics of Lesser Snow Geese
(University of California Press, 1998)
Birds that exhibit a high degree of natal and breeding philopatry and normally breed in stable environments may suffer costs of philopatry if their habitat deteriorates. Female Lesser Snow Geese (Chen caerulescens caerulescens) ...
