This data package contains one table with morphometric and diet information for "non-die-off" seabirds captured and collected in southcentral and southwest Alaska. Data pertains to birds captured (live) or collected (lethally) including, bird identification numbers, sampling dates, geographic locations, body measurements, diets (from either stomach contents or regurgitated prey), and sex and age of the bird when discernible. Common Murres (Uria aalge) and Black-legged Kittiwakes (Rissa tridactyla) were captured from their breeding colonies in lower Cook Inlet, Alaska, 2016-2023. Kittiwakes, murres, Glaucous-winged Gulls (Larus glaucescens) and Horned Puffins (Fratercula corniculata) were collected in Prince William Sound, Cook Inlet, and Unalaska.

This dataset consists of three tables, 1) taxonomy, 2) contributors, and 3) shorebird morphological measurements collected from various species captured from 1977-2021. In addition, photographs of plumage patterns are available for several species. Researchers with the U.S. Geological Survey - Alaska Science Center, along with collaborators from many government agencies and research institutions, have studied shorebirds at numerous sites across North America, the Pacific Ocean, Australia, and New Zealand. This release includes over 10,000 observations relating to 35 shorebird species.

These data describe marine bird and mammal surveys conducted in glacial fjords of coastal Alaska. Data were collected to document the at-sea distribution and abundance of marine birds and mammals in Glacier Bay National Park (2004), Prince William Sound (2010), Icy Bay (2011) and Yakutat Bay (2011). Following standard US Fish and Wildlife protocols for strip surveys.

The data in this table document the numbers of four species of shorebird counted during aerial surveys of coastal sites in western Alaska. Survey regions encompassed coastline between the mouths of the Kuskokwim and Yukon rivers, and the northern coast of the Alaska Peninsula from the mouths of the Kvichak and Naknek rivers to Nelson Lagoon. Surveys were flown from 7-9 September 2018 and 20-22 August 2019. Also provided are two Keyhole Markup Language (KML) files with the start and end points of the aerial survey transect segments, and copies of the aerial survey images from which the counts were derived.

These data are part of the Gulf Watch Alaska (GWA) long-term monitoring program and contain diet data from Black-legged Kittiwakes (BLKI), Rhinoceros Auklets (RHAU), and Tufted puffins (TUPU) located on Middleton Island in Prince William Sound, Gulf of Alaska. The first table consists of information on seabird diet samples including the sampling method and number of prey types identified per sample ("seabirdDiets_foodSample_middletonIsland.csv"). The second table is similar to the first table, however, the samples have been subdivided by individual prey species ("seabirdDiets_samplePrey_middletonIsland.csv"). The third table consists of information specific to sampled prey items, such as prey taxa identification and morphometrics ("seabirdDiets_preyItems_middletonIsland.csv"). The fourth table consists of processed diet information and indices specific to Black-legged Kittiwake and Rhinoceros Auklet prey ("seabirdDiets_RHAU_BLKI_diets_middletonIsland.csv"). The fifth table contains prey species and seabird species taxonomy information ("seabirdDiets_speciesTaxonomy_middletonIsland.csv"). All samples included in the tables of this data release were collected during the spring and summer months from 1978-2022.

These data are part of the Gulf Watch Alaska (GWA) long term monitoring program, pelagic monitoring component. This dataset consists of one table, providing the results of surveys conducted to document the summer at-sea distribution and abundance of marine birds and mammals in Prince William Sound, Alaska. Surveys followed standard U.S. Fish and Wildlife protocols for strip surveys. Data include: transect ID, date, time, latitude, longitude, record number, data type, animal species, count, behavior, plumage, distance, observers, observer conditions, the altitude of the survey, ice presence, trip ID, beaufort, transect type, transect width, and comments.

This data package presents legacy data collected during 1985-1987 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) define the time periods that are most important for geese, 2) determine if certain portions of Izembek Lagoon are more important than other areas, 3) evaluate factors that influence distribution of geese within Izembek Lagoon, and 4) compare use by geese of Izembek Lagoon with use of other adjacent lagoons to determine relative importance. 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 reference archives metadata about the collection of geospatial data which may be stored in a variety of file formats (e.g. shapefile, geodatabase) for the Oregon Coast NWRC: Surface Nesting Seabirds - Aerial Photographic Colony Surveys survey (PRIMR ID: FF01RORG00-002 and FF01RTAR00-002). Starting in 2009 photographs were taken using digital photography (hand-held camera). Counts (from photographs) were initially started in 2009 but were not completed until 2020. These geospatial files represent the raw count of seabirds from non-georeferenced images. These raw point counts are not registered to any geospatial coordinates. They only line up with the image from which they were derived, no geospatial coordinates are attached to the raw images. Results of the counts are put through a secondary check and then numbers are entered into the complete Seabird Colony Count Catalog (Database) which can be downloaded from , which is the authoritative source for bird count data collected by the U.S. Fish and Wildlife Service (USFWS). Oregon Coast National Wildlife Refuge Complex manages an Imagery Program for collecting refuge-wide aerial imagery datasets that are used to monitor nesting seabirds on offshore islands. Aerial flights are generally conducted annually to monitor population status and trends, but the imagery is used for other resource monitoring purposes. Aerial photography has served as the primary means for monitoring populations of nesting seabirds (Census years include 1988, 1994, 2006, and 2014), and the subsequent analysis of long-term seabird colony legacy data in the Pacific Northwest as a regional baseline. The 2009 set of photographs have been used to complete a refuge-wide colony subsample count for 2009, where each photograph in the subsample has a digital point file (hand count) of nesting seabirds stored in a geodatabase format. We counted a subsample of Oregon coast colonies using a size- and geographical-based stratified random sampling approach for all other survey years. The subsample was selected based on common murre populations, therefore no inferences can be drawn about Brandt’s cormorants without additional colony subsampling. The subsampling approach was informed by recommendations from bio-statistical experts based on colony size and location. We subsampled 45 colonies, which were counted over time. Including census year counts, our subsample years were 1988, 1994, 1997, 2000, 2003, 2006, 2009, 2012, and 2014. A power analysis for the sampling design recommended for the Protocol Framework indicated that a minimum of 16 common murre within each region needed to be counted each year in order detect an average decline of 3.35% per year over a 15-year period (cumulative 40% decline) with 80% probability. With guidance from two statisticians, we randomly selected 6 small and 9 medium/large colonies per region for a total of 45 colonies to be counted each year to detect changes across the Oregon Coast.
