These data provide estimates of abundance and measures of harvest pressure for five species (mallard, American green-winged teal, wood duck, ring-necked duck, and Common and Barrows' goldeneyes combined) of ducks breeding in the Atlantic Flyway of North America, 1998-2017. Abundance data are based on federal and state surveys encompassing southern Ontario, Quebec, and Maine south to Florida. Harvest rates are provided for those species with adequate band recovery data (mallard wood duck, green-winged teal), and absolute harvest is provided for those that do not (ring-necked duck, goldeneyes). Indices of harvest pressure are based on federal surveys. Also included are the number of wings of each species received from individual hunters on individual days during the 2004-2013 hunting seasons as part of a U.S. Fish and Wildlife Service survey in the U.S. portion of the Atlantic Flyway.

This dataset consists of estimates of population trends for 236 species and species complexes of North American birds, and bird taxonomic, primary habitat biome, or conservation status group relative abundance trajectories. Both sets of estimates cover the period 1970 - 2022. Sources of data include the North American Breeding Bird Survey (BBS), Christmas Bird Count (CBC), Waterfowl Breeding Population and Habitat Survey (WBPHS), and the American Woodcock Singing-ground Survey (SGS). The groups with collective relative abundance trajectories are Aridland, Dabbling and Diving Ducks, Eastern Forest, Geese and Swans, Grassland, Sea Ducks, Tipping Point, Waterbirds, and Western Forest.

There is a growing movement within natural resource management to view wildlife health as a cumulative outcome of many different factors, rather than simply the absence of disease. This inclusive understanding of health opens the door to management options that are more creative than traditional techniques to prevent or mitigate pathogens. The public health field uses a determinants of health framework to understand the physical, social, and cultural systems that impact health at the individual and community levels (National Academies of Sciences, Engineering, and Medicine 2016). Applying a similar framework to wildlife can help managers focus on tangible actions to positively impact wildlife health in the absence of disease (Wittrock et al. 2019). In the south-central United States, changes in water availability and quality resulting from changing temperature, precipitation, and land-use patterns can have significant impacts on the health of migratory birds that depend on wildlife refuges as seasonal habitat. These data were collected in partnership with several U.S. Fish and Wildlife Service National Wildlife Refuges across Oklahoma (n=2), New Mexico (n=3), and Louisiana (n=1, 8 individual refuges administratively grouped within the Southeast Louisiana Refuge Complex) to examine how managers define determinants of health for migratory birds and assess how those determinants may be impacted by local changes in water regimes. This data release contains nineteen (19) related datafiles and their associated metadata. For each participating refuge there are three files: an image file of the final conceptual diagram, a .csv file containing information about the elements in the diagram, and a .csv file containing information about the connections in the diagram. The conceptual diagram of migratory bird health was constructed using information collected through interviews with refuge personnel and supplemented (to gain additional context, when necessary) with refuge management documents and information on their public-facing websites. The diagrams are provided as .jpg files exported from the free system mapping and visualization program Kumu, in which they were created. Each diagram consists of nodes (referred to as elements) and relationships (referred to as connections). The elements and connections represent elements of the refuge system that were highlighted by personnel as playing an important role in migratory bird health or water availability. Detailed, narrative descriptions for each system component are provided in their respective .csv files. There is also a .csv file containing data from a pre-interview survey sent to each refuge to gather basic information about the high-priority migratory bird guilds on their refuge, their management objectives in relation to migratory birds, and the water-related threats they consider highest concern.

This data package presents legacy data collected during 1985-1988 at Izembek Lagoon on the western end of the Alaska Peninsula. The data were collected in support of a multi-year study focused on aircraft disturbance of waterfowl, particularly Black Brant, Emperor Geese, and Cackling Geese. The study was conducted at Izembek Lagoon and included several study sites within the lagoon: Halfway Point, Grant Point, Outer Marker, Quarter Point, Applegate Cove, Norma Bay, Round Island, and Banding Island. The primary objectives were to 1) determine the effects of aircraft overflights and other human activities on the behavior, distribution, and habitat use of Brant, Cackling, and Emperor Geese, 2) examine noise levels associated with aircraft overflights and determine whether the behavioral response of geese is influenced by noise, and 3) evaluate the potential impact of disturbance on the energetic requirements of fall-staging Brant. The raw data are provided in a .CSV format, however, PDF digital scans of original field data sheets, tables, figures, and maps are also available upon request.

This data package presents raw legacy data collected during 1980 on the Yakutat Forelands of southeast Alaska. The data were collected to identify and understand the occurrence and distribution of birds and mammals in the ocean and wetlands near Yakutat. Migration "sea watches", aerial surveys, and ground plot surveys were conducted in the foreland area of Yakutat in spring (April - May) and fall (August - October) of 1980. The data are presented as PDF files of digitally scanned information as follows: 1) original field data forms describing migration "sea watches" in spring and fall, 2) original field data forms describing aerial survey observations of migratory birds in spring and fall, 3) photos, maps, and notes describing locations of aerial survey observations, 4) original field data of birds observed on ground plots in spring and fall, 5) original field data of habitat classifications for ground plots, 6) original field data of observations of habitat use by migratory birds, and 7) notes on images and maps used in analyses of habitat data.

This metadata document describes VHF tracking data for Greater White-fronted Geese (Anser albifrons) marked annually (1987-1991) in Alaska and the Klamath Basin (Oregon and California) and subsequently tracked through the Pacific Flyway (primarily in Alaska, California, and Mexico). Only tracking data for geese marked or located, at least once, in Alaska are included in this data package. Data for Greater White-fronted Geese tagged at Klamath Basin that were never relocated in Alaska are not included.
