This data package presents legacy data on Emperor Goose, Cackling Goose, Black Brant, and Greater White-fronted Goose, breeding biology, behavior, and morphology collected at study sites near Kokechik Bay on the Yukon Delta National Wildlife Refuge (previously Clarence Rhodes National Wildlife Refuge), Alaska during the summers of 1982 through 1988. These data were collected to provide a basis for the evaluation of long-term changes in Emperor Goose and other waterfowl biology on the Yukon-Kuskokwim Delta, Alaska.

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 proportion of time brant spent foraging, resting, and in flight during natural environmental conditions. 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 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 certian 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.

These data are in two tables: 1) table relating to emperor goose nest visit, nest fate, and nest dispersal distances on the Yukon-Kuskokwim Delta in Alaska, 2000-2017; 2) table with means and standard deviations for posterior distributions of predicted nest-age and year specific daily nest survival probabilities for emperor geese derived from estimates reported by Thompson et al. (2023) for the Manokinak River study area. These parameters were used as informative prior distributions in the modeling process. The code used to conduct the analyses is also included as a text file.

These data are in four tables relating to nest visit data of Emperor Geese on the Yukon-Kuskokwim Delta in Alaska, 1994-2017. The tables provide: (1) nest visit and hatch success, (2) visit history, (3) capture history, and (4) environmental covariates such as fox and vole abundance and weather data. The code used to conduct the analyses is also included as a text file.
