Nest prospecting by Common Goldeneyes

Goldeneye (Bucephala clangula) Science Article 2 abstract We studied nest prospecting by Common Goldeneye (Bucephala clangula) females in north-central Minnesota. Adults unsuccessful in nesting, those with broods, and nonnesting yearlings were captured in nests while prospecting. Prospecting began in late May and continued into early July. Active nests received up to 25 prospecting visits per […]

Host-parasite relatedness shown by protein fingerprinting in a brood parasitic bird

Goldeneye (Bucephala clangula) Science Article 1 abstract Brood parasitism as an alternative female breeding tactic is particularly common in ducks, where hosts often receive eggs laid by parasitic females of the same species and raise their offspring. Herein, we test several aspects of a kin selection explanation for this phenomenon in goldeneye ducks (Bucephala clangula) […]

A Management Plan for Barrow’s Goldeneye (Bucephala islandica; Eastern population)

Barrows Goldeneye (Bucephala islandica) Science Article 1 abstract The world distribution of Barrow’s Goldeneye (Bucephala islandica) consists of threeseparate populations: 150 000 to 200 000 birds in western North America (Eadie et al 2000),a resident population of 2000 in Iceland (Gardarsson 1978), and approximately 4500 birds ineastern North America (Savard and Dupuis 1999; Robert et […]


Barrows Goldeneye (Bucephala islandica) Science Article 4 abstract We studied the timing, duration, and rate of wing molt of male Barrow’s Goldeneye (Bucephala islandica). The mean daily change in primary feather length was 2.6%, which is consistent with rates reported for other waterfowl species. The mean length of the flightless period was 31 days (range: […]


Barrows Goldeneye (Bucephala islandica) Science Article 6 abstract Naturally occurring stable isotopes in foodwebs can be used to determine the relative contributions of endogenous and exogenous nutrients to avian eggs in cases where birds move between isotopically distinct biomes or habitats to breed. We measured 13C and 15N values in somatic muscle tissues and eggs […]

Further Evidence of Long-term Pair Bonds in Ducks of the Genus Bucephala

Barrows Goldeneye (Bucephala islandica) Science Article 3 abstract In holarctic ducks, pair formation occurs during the winter or the spring migration, or both, and pair bonds are seasonal, usually lasting until the onset of incubation by the female (McKinney 1986). Because males desert their mates during incubation and leave thebreeding grounds for molting, it has […]
