“…Rather, factors that affect reproductive success and recruitment may be more apt to influence population increase. This is similar to factors that appear to limit rate of increase in dusky Canada geese (Bromley and Rothe 2003, Grand et al 2006, Fondell et al 2008, the Canada goose population that is geographically and taxonomically closest to Vancouver Canada geese (Scribner et al 2003).…”

Winter Distribution, Movements, and Annual Survival of Radiomarked Vancouver Canada Geese in Southeast Alaska

Management of Pacific Flyway Canada geese (Branta canadensis) requires information on winter distribution of different populations. Recoveries of tarsus bands from Vancouver Canada geese (B. canadensis fulva) marked in southeast Alaska, USA, ≥4 decades ago suggested that ≥83% of the population was non‐migratory and that annual adult survival was high (Ŝ = 0.836). However, recovery distribution of tarsus bands was potentially biased due to geographic differences in harvest intensity in the Pacific Flyway. Also, winter distribution of Vancouver Canada geese could have shifted since the 1960s, as has occurred for some other populations of Canada geese. Because winter distribution and annual survival of this population had not recently been evaluated, we surgically implanted very high frequency radiotransmitters in 166 adult female Canada geese in southeast Alaska. We captured Vancouver Canada geese during molt at 2 sites where adults with goslings were present (breeding areas) and 2 sites where we observed nonbreeding birds only. During winter radiotracking flights in southeast Alaska, we detected 98% of 85 females marked at breeding areas and 83% of 70 females marked at nonbreeding sites, excluding 11 females that died prior to the onset of winter radiotracking. We detected no radiomarked females in coastal British Columbia, or western Washington and Oregon, USA. Most (70%) females moved ≤30 km between November and March. Our model‐averaged estimate of annual survival (Ŝ = 0.844, SE = 0.050) was similar to the estimate of annual survival of geese marked from 1956 to 1960. Likely <2% of Vancouver Canada geese that nest in southeast Alaska migrate to winter areas in Oregon or Washington where they could intermix with Canada geese from other populations in the Pacific Flyway. Because annual survival of adult Vancouver Canada geese was high and showed evidence of long‐term consistency, managers should examine how reproductive success and recruitment may affect the population.

“…At the Copper River Delta, Bald Eagles (Haliaeetus leucocephalus) are an important nest predator and Grand et al (2006) showed that the rate of Bald Eagle predation on Canada Goose (Branta canadensis) nests on the Copper River Delta was mediated by the availability of anadramous fish (eulachon, Thaleichthys pacificus), which served as alternative prey for eagles. Nest survival of both Canada Geese and Red-throated Loons at the Copper River Delta during 2001-2003 was highest in 2002, when the presence of eulachon was most protracted .…”

Factors influencing nest survival and productivity of Red-throated Loons (Gavia stellata) in Alaska

Identifying post-breeding migration and wintering distributions of migratory birds is important for understanding factors that may drive population dynamics. Red-throated Loons (Gavia stellata) are widely distributed across Alaska and currently have varying population trends, including some populations with recent periods of decline. To investigate population differentiation and the location of migration pathways and wintering areas, which may inform population trend patterns, we used satellite transmitters (n = 32) to describe migration patterns of four geographically separate breeding populations of Red-throated Loons in Alaska. On average (± SD) Red-throated Loons underwent long (6,288 ± 1,825 km) fall and spring migrations predominantly along coastlines. The most northern population (Arctic Coastal Plain) migrated westward to East Asia and traveled approximately 2,000 km farther to wintering sites than the three more southerly populations (Seward Peninsula, Yukon-Kusko-kwim Delta, and Copper River Delta) which migrated south along the Pacific coast of North America. These migration paths are consistent with the hypothesis that Red-throated Loons from the Arctic Coastal Plain are exposed to contaminants in East Asia. The three more southerly breeding populations demonstrated a chain migration pattern in which the more northerly breeding populations generally wintered in more northerly latitudes. Collectively, the migration paths observed in this study demonstrate that some geographically distinct breeding populations overlap in wintering distribution while others use highly different wintering areas. Red-throated Loon population trends in Alaska may therefore be driven by a wide range of effects throughout the annual cycle.

“…Second, we tested whether daily survival rate (DSR) was constant or changed in a linear or quadratic fashion with nest age. We reasoned (1) that DSR should increase later in the nesting cycle because pré-dation of nests in poor locations normally occurs early in the nesting cycle of waterfowl (Klett and Johnson 1982) but (2) that DSR could increase but then decline late in incubation, which Grand et al (2006) attributed to shifts in female behavior. Third, we constructed models whereby DSR varied linearly and nonlinearly with nest initiation date to evaluate the importance of timing of nesting.…”
