Waterbird Populations and Pressures in the Baltic Sea

This report outlines the results of the internationally coordinated census of wintering waterbirds in the Baltic Sea 2007-2009 undertaken under the SOWBAS project (Status of wintering Waterbird populations in the Baltic Sea). The estimated total number of wintering waterbirds was 4.41 million compared to 7.44 million during the last co-ordinated census 1992-1993. Despite the general declines stable or increasing populations of herbivorous species were recorded. While benthic carnivores with a coastal distribution have either shown moderate declines, stable or increasing populations.

Atlantic Flyway Sea Duck Survey

During the 1980's, restrictive harvest regulations linked to declines in mid-continent duck populations and restrictions on black duck harvest led to a shift in hunting pressure to lesser-utilized species, such as sea ducks. Concern among Atlantic coast waterfowl biologists about this increase in pressure on sea ducks led to a variety of surveys in different areas being conducted at different times, using a variety of techniques that were not compatible.

Survey of Wintering Sea Ducks and Waterbirds in Bristol Bay, Alaska

There is a dearth of information about bird use of certain areas of Bristol Bay during winter. This survey will fill in gaps of our knowledge and provide baseline winter abundance and distribution data for eastern Bristol Bay and the southern extent of sea ice, which varies annually. The area is subject to potential threats from offshore oil and gas development and from mining (i.e., Pebble mine). The aerial survey will be done using USFWS Kodiak fixed-wing aircraft and pilots and will test the proposed survey methodology..

Embedded Lead Shot and Infliction Rates in Common Eiders

Wildl. Biol. 12: 257-265.
“As the Eider is a bird very resistant to shot, often 2-3 birds are wounded for each that is shot dead…”
(Müller, South Greenland, 1906)
The large numbers of common eiders Somateria mollissima and king eiders S. spectabilis wintering
in southwest Greenland are subject to intensive hunting, and in addition to direct harvest an unknown
number of birds are wounded and become carriers of embedded lead shot. We conducted the first
assessment of the magnitude of this undesirable side effect of hunting in Greenland by X-raying 879

North American Environmental Atlas (CEC, CCA, CCE)

Mapping North America's shared Environment
The North American Environmental Atlas is an interactive mapping tool to research, analyze and manage
environmental issues in Canada, United States and Mexico. All signers of the Migratory Bird Treaty.
Maps are downloadable free of charge and available in an easy to use map viewer format.
The CEC uses maps in the Atlas to:
•Identify priority areas to conserve biodiversity
•Track cross-border transfers of pollutants
•Monitor CO2 emissions across major transportation routes
