Adult survival and productivity of Northern Fulmars in Alaska

The population dynamics of Northern Fulmars (Fulmarus glacialis) were studied at the Semidi Islands in the western Gulf of Alaska. Fulmars occurred in a broad range of color phases, and annual survival was estimated from the return of birds in the rarer plumage classes. A raw estimate of mean annual survival over a 5-year period was 0.963, but a...

Aggressive encounters between tundra swans and greater white-fronted geese during brood rearing

Interspecific aggression in waterfowl (Anatidae) is relatively common (McKinney 1965; Kear 1972; Savard 1982, 1984), but interactions leading to mortality of one of the combatants are rarely-observed in the wild. A recent debate (Livezey and Humphrey 1985a, 1985b; Nuechterlein and Storer 1985a, 1985b; Murray 1985) has centered on the proximate and...

An inexpensive device for recording animal behavior

Recording animal behavior is tedious and time consuming when behaviors are recorded on tape and transcribed to data sheets. Data loggers circumvent these problems, but can be prohibitively expensive and may require extensive programming (see Hensler et al. [1986]). I describe an inexpensive, efficient alternative for recording behavioral...

Autumn staging of cackling Canada geese on the Alaska Peninsula

Cackling Canada Geese Branta canadensis minima undergo a long (2,800 km) migration between their autumn staging areas on the Alaska Peninsula and wintering areas in Oregon and California. Adults and young lost an average of 543 g during this migratory flight. Weight gains between fledging and autumn migration are essential for the successful...

Common Murre (Uria aalge) attendance patterns at Cape St. Mary's, Newfoundland

Attendance patterns of common murres (Uria aalge) at Cape St. Mary's, Newfoundland, were observed during hatching to post-fledging periods of 1980 to 1984. Six study plots on breeding ledges (ca. 450 birds total) and a "club" on the water were monitored for seasonal fluctuations in numbers attending. Attendance on ledges was similar between years...

Copulation and mate guarding in the Northern Fulmar

I studied the timing and frequency of copulation in mated pairs and the occurrence of extra-pair copulation (EPC) among Northern Fulmars (Fulmarus glacialis) for 2 yr. Copulation peaked 24 days before laying, a few days before females departed on a prelaying exodus of about 3 weeks. I estimated that females were inseminated at least 34 times each...

Cumulative impacts of oil fields on northern Alaskan landscapes

Proposed further developments on Alaska's Arctic Coastal Plain raise questions about cumulative effects on arctic tundra ecosystems of development of multiple large oil fields. Maps of historical changes to the Prudhoe Bay Oil Field show indirect impacts can lag behind planned developments by many years and the total area eventually disturbed can...

Dehydration of seabird prey during transport to the colony: Effects on wet weight energy densities

We present evidence to indicate that dehydration of prey transported by seabirds from capture sites at sea to chicks at colonies inflates estimates of wet weight energy densities. These findings and a comparison of wet and dry weight energy densities reported in the literature emphasize the importance of (i) accurate measurement of the fresh...

Did the 1982-1983 El Niño-Southern Oscillation Affect Seabirds in Alaska?

The causes and effects of the oceanographic and atmospheric phenomena known as El Nino and the Southern Oscillation (ENSO) have been studied intensively in recent years (Cane 1983, Rasmusson and Wallace 1983, Barber and Chave 1983, Cane and Zebiak 1985). ENSOs occur at semiregular intervals of 3-4 years, and the stronger events have important...

Incidental catch of marine birds and mammals in fishing nets off Newfoundland, Canada

Summer surveys of the incidental catch of marine birds and mammals in fishing nets around the east coast of Newfoundland indicated that over 100 000 animals were killed in nets during a 4-year period (1981–1984). Composition of catches depended on foraging behaviour, regional abundance, and the degree of foraging aggregation of different species....
