Worldwide Species Action Plans

Yellow-billed Loon action planNorthern Alaska breeding grounds support an average of 3,369 Yellow-billed Loons (Gavia adamsii), and about 780 more occur in western Alaska, making this species one of the least common regularly breeding birds in the mainland United States (Section 6ûE). Because of its restricted range, small population size, specific habitat requirements, and the potential for oil development throughout its U.S. breeding range, the Yellow-billed Loon has been a Species of Management Concern, or Bird of Conservation Concern, to the U.S. Fish and Wildlife Service since 1995 (USFWS 1995, 2002a) and is the subject of a recent petition for listing under the Endangered Species Act (Center for Biological Diversity 2004). The first part of this publication, the Status Assessment, provides a comprehensive and critical review of the published and unpublished data on Yellow-billed Loon population size, population trend, and potential threats to the population and its breeding and wintering habitat. The literature review relies heavily on that presented in North (1994), Barr (1997), and Fair (2002). The Status Assessment identifies gaps in our knowledge and in current monitoring programs. The last section of the publication, the Conservation Plan, details 7 objectives and 29 specific strategies to fill gaps identified in the Assessment. The format of the Status Assessment follows that suggested by the U.S. Fish and Wildlife Service (USFWS 2000). The preparation of this document was requested and funded by the Nongame Bird Office, Division of Migratory Birds, Region 7, U.S. Fish and Wildlife Service. This document is a compilation of biological data and a description of past, present, and potential future threats to the Yellow-billed Loon.
