Persistence rates and detection probabilities of oiled king eider carcasses on St Paul Island, Alaska Persistence rates and detection probabilities of oiled king eider carcasses on St Paul Island, Alaska
Following an oil spill off St Paul Island, Alaska in February 1996, persistence rates and detection probabilities of oiled king eider (Somateria spectabilis) carcasses were estimated using the Cormack-Jolly-Seber model. Carcass persistence rates varied by day, beach type and sex, while detection probabilities varied by day and beach type. Scavenging, wave action and weather influenced...

Productivity of nesting spectacled eiders on the lower Kashunuk River, Alaska Productivity of nesting spectacled eiders on the lower Kashunuk River, Alaska
We studied the chronology and success of nesting Spectacled Eiders (Somateria fischeri) along the lower Kashunuk River on the Yukon-Kuskokwim Delta from 1991-1995. Nest initiation dates ranged from 16 May-22 June. Median nest initiation dates were correlated with the break-up of ice on the Kashunuk River. Clutch sizes declined seasonally, and mean clutch size varied among years ranging...

Exposure of Spectacled Eiders and other diving ducks to lead in western Alaska Exposure of Spectacled Eiders and other diving ducks to lead in western Alaska
Lead poisoning, resulting from ingestion of spent shot, has been identified as a cause of mortality in Spectacled Eiders (Somateria fischeri) on the Yukon–Kuskokwim Delta, Alaska. We examined lead-exposure rates of adult and juvenile Spectacled Eiders and other diving ducks, using atomic absorption spectrophotometry of blood samples. Additionally, we X-rayed birds in the field to...

Variation in incubation periods and egg metabolism in mallards: Intrinsic mechanisms to promote hatch synchrony Variation in incubation periods and egg metabolism in mallards: Intrinsic mechanisms to promote hatch synchrony
We investigated factors affecting incubation time and metabolic rates of Mallard (Anas platyrhynchos) eggs incubated under constant environmental conditions. Time required to reach the star-pipped stage of hatch varied significantly among females, but not with laying sequence or egg size. Metabolic rate of eggs varied positively with position in the laying sequence and tended to vary...

Habitat use by nesting and brood rearing northern pintails on the Yukon-Kuskokwim Delta, Alaska Habitat use by nesting and brood rearing northern pintails on the Yukon-Kuskokwim Delta, Alaska
We studied habitat use by nesting and brood-rearing northern pintails (Anas acuta) on the coastal Yukon-Kuskokwim (Y-K) Delta, 1991-93. We used a digital habitat map constructed from color infrared aerial photos to assign habitat types to nest and brood locations and estimate habitat availability. Sixty-nine percent of females nested on slough banks in highly saline, tidally influenced...

Survival of spectacled eider adult females and ducklings during brood rearing Survival of spectacled eider adult females and ducklings during brood rearing
We studied survival of adult female and duckling spectacled eiders (Somateria fischeri) during brood rearing on the Yukon-Kuskokwim Delta, Alaska from 1993 to 1995. Duckling survival to 30 days of age averaged 34% with a 95% confidence interval from 25 to 47%. Half (49%) of radiomarked adult females had lost all their ducklings by 30 days after hatch. Most (74%) duckling mortality...
