Seasonal occurrence of migrant whimbrels and bristle-thighed curlews on the Yukon-Kuskokwim Delta, Alaska
Migrant Whimbrels (Numenius phaeopus) and Bristle-thighed Curlews (N. tahitiensis) were recorded during five summers along coastal tundra of the Yukon-Kuskokwim Delta, Alaska. From June to September, 1975-1979, 358 flocks totalling 1,265 curlews were observed; an additional 54 flocks were identified by vocalization alone. Among the 359 flocks identified to species, 52% were of Whimbrels, 47% were

Yellow birds stand out in a crowd
Highly visible auxiliary markers, such as neck collars, nasal saddles, patagial tags, and leg streamers, are used regularly and effectively with banding in studying migration and distribution of large birds (e.g. waterfowl, birds of prey, wading birds). Simply stated, a large bird can accommodate a marker that is large enough to be seen readily by an observer but still small enough not to alter be

Memorial to a Black Turnstone: An examplar of breeding and wintering site fidelity
Most of us who have banded long-distance migrants are aware, through recaptures of individuals, of the high degree of site fidelity exhibited by many bird species. It is not uncommon for a bander to have a marked bird remain in the vicinity of its banding site throughout a season and then to recapture or sight the bird there during the following season, or occasionally for several successive seaso

An annotated bibliography of literature on Alaska water birds
The demand for information on birds in Alaska has surged within the past few years, primarily because of the need to adequately assess the impacts of a wide range of planned developments. The accompanying increase in studies of avian populations has resulted in a growing need for a comprehensive bibliography of Alaska ornithology. An initial effort by Bartonek and Lensink (1978) provided a list of
