Waterfowl Management Handbook

The need for a single source of information about the management of waterfowl and their habitat was originally suggested by the north-central region of the U.S. Fish and Wildlife Service. Much of this information exists in scientific papers, unpublished reports, or has never been recorded, and thus is not readily accessible by waterfowl managers. More...

Using Stable Isotopes and Trace Elements to Link Seasonal Habitats of Neotropical Migratory Shorebirds

Identifying linkages between the seasonal habitats of migratory birds, especially neotropical migrants, is critical to conservation efforts and to effectively focus management actions. For most neotropical migrants, however, virtually nothing is known about which habitats are limiting, because the links between their seasonal habitats on different More...

Inventory of montane - and alpine - nesting shorebirds in Alaska

Mountains are the single dominant physiographic feature throughout most of Alaska. Indeed, mountains are such a defining feature of arctic Alaska and Beringia that they account for over 20 percent of the land area in the entire Holarctic (excluding the Greenland ice sheet). Not surprisingly, the avifauna of the region has been strongly More...

Geolocator Tags Tested on Wisconsin Common Loons

Scientists with the U.S. Geological Survey and the Wisconsin Department of Natural Resources are evaluating a new way of monitoring movements and behavior of common loons. Miniature archival geolocator tags were attached to 18 adult common loons in northern Wisconsin this past summer.

Molecular Population Genetic Structure in the Piping Plover

The Piping Plover (Charadrius melodus) is a migratory shorebird currently listed as Endangered in Canada and the U.S. Great Lakes, and threatened throughout the remainder of its U.S. breeding and winter range. In this study, scientists undertook the first comprehensive molecular genetic-based investigation of Piping Plovers. The primary goals were More...

Sources of Organochlorine Contaminants and Mercury in Seabirds from the Aleutian Archipelago of Alaska

The Aleutian archipelago of Alaska, which separates the North Pacific Ocean from the Bering Sea, supports a diverse and abundant community of resident and migratory seabirds, comprising over 26 species and 10 million birds. However, comparatively little data exist on sources of environmental contaminants for this community despite extensive More...

Potential Environmental Contaminant Risks to Avian Species at Important Bird Areas in the Northeastern United States

From the abstract: Environmental contaminants can have profound effects on birds, acting from the molecular through population levels of biological organization. An analysis of potential contaminant threats was undertaken at 52 Important Bird Areas (IBAs) within the northeastern Atlantic coast drainage. Using geographic information system More...

Movements of Northern Pintail Ducks with Satellite Transmitters

This study examines the likelihood that migratory birds will transmit highly pathogenic H5N1 avian influenza from Asia to North America, using Northern Pintails (Anas acuta) as a model for viral transmission. Evaluating exchange of avian-borne pathogens between Asia and North America by migratory birds requires an understanding of where birds More...

Migratory Connectivity and Seasonal Interactions of Shorebirds as Potential Vectors of Avian Influenza

This project investigates the role of wild migratory birds in the transmission of highly pathogenic avian influenza (HPAI) H5N1. Scientists will determine the precise migratory routes and use of Asian stopover areas by Alaska-breeding Bar-tailed Godwits. Field surveillance sampling targets HPAIH5N1 and non-H5N1 viruses in Alaska and assess More...

Hawaiian Native Birds Research

Introduction to Hawaiian studies of native birds: Hawaiian forest birds, endangered Palila (Loxioides baillieu), endangered Nene (Branta sandvicensis), birds elsewhere in the Pacific, waterbirds and seabirds, and endangered Laysan ducks (Anas laysanensis).

Conservation Genetics of Shorebirds: Identification of Conservation Units, Genetic Diversity, and Population-Specific Markers for North American Shorebird Species of Concern

Conservation Genetics of Shorebirds uses molecular techniques to describe genetic structure and diversity in North American shorebirds (order: Charadriiformes) to facilitate population maintenance and recovery of these migratory birds.
