We were asked to evaluate the suitability of a turbine powered airplane for waterfowl surveys in interior British Columbia. Previous surveys had been completed by helicopter (Andre Breault, personal communication).
In Fall 2005, the National Flyway Council and the Wildlife Management Institute conducted a mail survey of duck hunters in 49 U.S. states. A random sample of 29,862 duck hunters was contacted using names drawn from the Harvest Information Program database. Of the 27,555 survey forms delivered, 10,887 were returned (40% response); 10,219 respondents were “active” duck hunters.
The following briefing material has been assembled for use by the Pacific Flyway Council and by U. S. Fish and Wildlife Service
personnel in formulating recommendations for the 2011-2012 waterfowl hunting seasons. This collection of harvest, population,
and hunter data can also serve as a desk-top reference for providing responses to inquiries from agency personnel, the media, and public.
A few points to mention with regard to the information contained in this report:
Wiggins, D. (2005, October 17). Harlequin Duck (Histrionicus histrionicus): a technical conservation assessment. [Online]. USDA Forest Service, Rocky Mountain Region.
This study is a large scale, multi-year, collaborative project that will use satellite telemetry to document annual migration patterns and habitat use. Driven by a lack of knowledge on sea duck distribution, migration patterns, and seasonal habitats used, the Sea Duck Joint Venture (SDJV) partnership has launched a large-scale satellite telemetry study of sea ducks in the Atlantic Flyway. From 2009 to 2013, about 300 transmitters will be deployed in four species: Black Scoter, Surf Scoter, White-winged Scoter, and Long-tailed Duck - all species of high conservation concern.
More than half of North American sea duck populations have apparently declined over the past 2-3 decades, although reasons for declines are unknown. Population delineation (i.e., the links among breeding, molting, wintering, and staging areas) is critical information needed to design and interpret monitoring surveys, to better understand population ecology and population dynamics, and determine limiting factors and potential strategies to improve conservation status of sea ducks.
The Atlantic Seaduck Project is being conducted to learn more about the breeding and molting areas of seaducks in northern Canada and more about the feeding ecology of seaducks on wintering areas, especially Chesapeake Bay. Satellite telemetry is being used to track surf scoters wintering in Chesapeake Bay, Maryland, and black scoters on migrational staging areas in New Brunswick, Canada, to breeding and molting areas in northern Canada
