Flexible time budgets in breeding Common Murres: Buffers against variable prey availability

Mortality rates of canvasbacks were estimated from band-recovery records. The annual rate of mortality of immatures during the first year was 77 per cent. Annual mortality rates of adults ranged from 35 to 50 per cent. Mortality rates of females were higher than those of males. Relatively larger numbers of immatures and adult females were shot...

Identification of a herpes-like virus in sea otters during rehabilitation after the T/V Exxon Valdez oil spill

During implantation of radiotelemetry devices in sea otters (Enhydra lutris) at the Seward Otter Rehabilitation Center, surgical team members noted ulcers in the oral cavity of each of five animals examined. Oral lesions were identified in 25 of 27 otters examined at the center. Histological evaluation of the lesions revealed focal areas of...

Immediate impact of the 'Exxon Valdez' oil spill on marine birds

On 24 March 1989, the oil tanker 'Exxon Valdez' spilled 260,000 barrels of crude oil in Prince William Sound, Alaska. Oil eventually drifted over $30,000\ {\rm km}^{2}$ of coastal and offshore waters occupied by approximately one million marine birds. More than 30,000 dead birds of 90 species were retrieved from polluted areas by 1 August 1989. Of...

Incubation rhythm in the Fulmar Fulmarus glacialis: Annual variation and sex roles

I monitored the incubation schedules of Fulmars Fulmarus glacialis in an Alaskan colony by observing nests where the male and female were of different colour phases. Complete shifts of up to 16 days were recorded; the average shift in mid-incubation was 4–6 days. Mean shift length was inversely correlated with hatching success in 5 years,...

Individual variation in behavior and breeding success of Northern Fulmars

In a sample of breeding Northern Fulmars (Fulmarus glacialis) observed in 4-5 years, up to 43% of the variability in 13 attributes of breeding behavior was consistent among individuals or pairs. Sample means for most attributes were correlated in a predictable way with annual levels of breeding success. Except for laying dates, there was little...

Is the polar bear (Ursus maritimus) a hibernator? Continued studies on opioids and hibernation

Polar bear behavior and biochemistry suggest they may have the ability to hibernate year-round, even though this species is not considered to be a true hibernator. This observation, plus the discovery of a hibernation-induced trigger (HIT) in the blood of black bears, prompted the examination of polar bear blood collected thoughout the year for...

Isolation of infectious hematopoietic necrosis virus from a leech (Piscicola salmositica) and a copepod (Salmincola sp.), ectoparasites of sockeye salmon Oncorhynchus nerka

Infectious haematopoietic necrosis (IHN) virus was isolated from freshwater leeches Piscicola salmositica and copepods Salmincola sp. removed from the gills of spawning sockeye salmon, Oncorhynchus nerka. This is the first report of the isolation of IHN virus from an animal other than salmonid fishes. High levels of IHN virus were also found in...

Monitoring St. Lawrence Island and Cape Thompson seabird populations

About 1.8 million seabirds of 12 species breed on St. Lawrence Island (Figure 1) - one of the largest aggregations of breeding seabirds in the subarctic Pacific. Colonies of least and crested auklets alone, totaling 1.5 million birds, contain a substantial proportion (perhaps 20%) of these species’ world populations. Large seabird colonies occur...

Nest-site selection by Emperor Geese and Cackling Canada Geese

Differences were found in habitat structure between nest sites of Emperor Geese (Chen canagicus) and Cackling Canada Geese (Branta canadensis minima) during a 5-year study (1982-1986) at Kokechik Bay, Alaska. Emperor Geese tended to select sites that afforded concealment from avian predators before incubation began. Cackling Canada Geese tended to...

Postrelease monitoring of radio-instrumented sea otters in Prince William Sound

Sea otters (Enhydra lutris) that were captured in western Prince William Sound (PWS) or the Gulf of Alaska, treated, and held in captivity at the temporary rehabilitation centers established in response to the T/V Exxon Valdez oil spill were instrumented with radio transmitters, released into eastern PWS, and monitored by radiotelemetry. We...

Procedures and rationale for marking sea otters captured and treated during the T/V Exxon Valdez oil spill

Four methods were used for marking sea otters (Enhydra lutris) captured and treated during the response to the T/V Exxon Valdez oil spill. Colored and numbered flipper tags were placed on each sea otter that was brought to the otter treatment centers. These tags allowed individual recognition and permitted the tracking of individuals through the...

Seasonal movements of adult female polar bears in the Bering and Chukchi seas

Ten adult female polar bears (Ursus maritimus) were fitted with satellite telemetry collars during March 1986 in the Kotzebue Sound area of the Chukchi Sea. During March-April 1987, 2 of these bears were refitted with satellite telemetry collars and an additional 10 adult females were collared in the northern Bering and eastern Chukchi seas. Data...
