Age and Sex of Common Murres Uria Aalge Recovered during the 1997-98 Point Reyes Tarball Incidents in Central California

چکیده
Large numbers of Common Murres Uria aalge have been killed by oil spills off central California since the early 20th century (Carter et al. 2001). Common Murres are abundant near breeding colonies on the continental shelf in the Gulf of the Farallones region where oil spills occur from marine vessels visiting San Francisco Bay (Ainley & Lewis 1974, Briggs et al. 1987, Ainley et al. 1996, Manuwal & Carter 2001). Since the mid 1980s, considerable effort has been made to quantify numbers of seabirds killed by major oil spills and chronic oiling off central California (Ford et al. 1987, Stenzel et al. 1988, Page et al. 1990, Nur et al. 1997, Carter et al. 2003b). This study is one of the first to quantify age and sex of all Common Murres recovered during an oiling event in California.

Investigation of a Largescale Common Murre ( Uria aalge) Mortality Event in California in 2015.
From August through December 2015, beachcast bird survey programs reported increased deposition of common murres ( Uria aalge) on central and northern California beaches, but not on southern California beaches. Coastal wildlife rehabilitation centers received more than 1,000 live, stranded, and debilitated murres from Sonoma County to San Luis Obispo County during August-October. Approximately ...
متن کاملIngestion of plastic marine debris by Common and Thick-billed Murres in the northwestern Atlantic from 1985 to 2012.
Plastic ingestion by seabirds is a growing conservation issue, but there are few time series of plastic ingestion with large sample sizes for which one can assess temporal trends. Common and Thick-billed Murres (Uria aalge and U. lomvia) are pursuit-diving auks that are legally harvested in Newfoundland and Labrador, Canada. Here, we combined previously unpublished data on plastic ingestion (fr...

Taking the Bite Out of Winter: Common Murres (Uria aalge) Push Their Dive Limits to Surmount Energy Constraints
Diving seabirds that overwinter at high latitudes experience persistent cold exposure, short days and associated declines in ocean productivity that can challenge their ability to balance daily energy budgets. We used dive-immersion geo-locators to test the hypothesis that pursuit-diving Commonmurres (Uria aalge) will respond to the challenges of winter in the North Atlantic through increased d...
متن کاملIndividual Winter Movement Strategies in Two Species of Murre (Uria spp.) in the Northwest Atlantic
Individual wintering strategies and patterns of winter site fidelity in successive years are highly variable among seabird species. Yet, an understanding of consistency in timing of movements and the degree of site fidelity is essential for assessing how seabird populations might be influenced by, and respond to, changing conditions on wintering grounds. To explore annual variation in migratory...
