Observational Data of Migratory Birds during Spring and Fall Migration and their use of Habitats in the Yakutat Foreland of Alaska in 1980
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.

Tracking Data for Tundra Swans (Cygnus columbianus)
공공데이터포털
This data release includes 2 child items with tracking data for Tundra Swans, a species that nests in coastal areas throughout Alaska and winters across a broad area of North America from the Pacific to Atlantic coasts. Child Item 1: "Argos Satellite Tracking Data for Tundra Swans (Cygnus columbianus) - Processed Data" -- Quality-controlled data collected from Argos satellite transmitters. Child Item 2: "Argos Satellite Tracking Data for Tundra Swans (Cygnus columbianus) - Raw Data" -- All raw data collected from Argos satellite transmitters, provided for completeness of the archive. The quality-controlled, "Argos Processed Data" (Child Item 1) are better suited for most analytical purposes.

Aerial Surveys of Shorebirds at Pre-migratory Staging Sites in Western Alaska, 2018-2019
공공데이터포털
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.
