Data available at the onset of this project (population trends and indices of contaminant exposure) raised concern that Barrow's goldeneye populations may have been injured by the oil spill, may not be fully recovered, and may continue to suffer deleterious effects of the spill. This project is designed to critically assess the recovery status of Barrow's goldeneye populations through assemblage and analysis of all existent, relevant data.
A perennial question in ornithology is whether flight has evolved mostly to facilitate access to food or as an anti-predator strategy. However, flight is an expensive mode of locomotion and species using flight regularly are associated with an expensive lifestyle. Using heart rate (HR) data loggers implanted in 13 female common eiders (Somateria mollissima), our objective was to test the hypothesis that a high level of flight activity increases their energy budget.
This report summarizes information about the status of duck populations and wetland habitats during spring 2012, focusing on areas encompassed by the U.S. Fish & Wildlife (USFWS) and Canadian Wildlife Services’ (CWS) Waterfowl Breeding Population and Habitat Survey. We do not include information from surveys conducted by state or provincial agencies. In the traditional survey area, which includes strata 1–18, 20–50, and 75–77 (Figure 1), the total duck population estimate (excluding scoters [Melanitta spp.], eiders [Somateria spp.
Black and white-winged scoters are not federally listed species but are protected under the
Migratory Bird Treaty Act. The North American Waterfowl Management Plan (2004) lists all
scoter species as decreasing in numbers in North America.

This report looks at three natural areas in the boreal forest that are critical for birds,
but that are coming under pressure from industry, hydropower, and climate change.
We discuss some strong policy steps governments must take in order to protect the
watery forest and the great biodiversity of birds it supports.
