This collection contains the original “raw” survey data that were recorded and transcribed by each observer during the Yukon-Kuskokwim Delta (YKD) Aerial Breeding Pair Survey. Left-front and right-front seat observers recorded data on geese, swans, and cranes since 1985, while data on eiders, ducks, and waterbirds was recorded by a right-rear seat observer since 1989. These raw transcribed data should be used to produce updated quality-control (QC) datasets by running the quality assurance/quality control script “AKaerial.R” whenever the quality control procedures are revised or modified. The data files in this collection were named using the following naming convention: YKD(YKG)YYYY_RawObs_OOOO, where YKD=Duck...

This collection of files contains temperature data files (.ttd files) downloaded directly from Tiny Tag devices, as well exported temperature data as .csv files for each nest monitored with Tiny Tags by year. File names include Tiny Tag number, site, year, and nest ID..ttd files can be viewed using Tinytag Explorer. Note, however, that the times displayed by Tinytag Explorer are calculated when the data is displayed and depend on the daylight saving settings of the PC at that time. For example, if a .ttd file is opened before and after DST settings change, then all times displayed by Tinytag Explorer will go forward or back. All .csv files were exported using the Tinytag Explorer during the same daylight savings...

Shorebirds are among the most rapidly declining species in North America (Rosenberg et al. 2019), with many long-distance migrants experiencing the greatest declines (Environment Canada 2020). Nonetheless, not all shorebirds are declining and there may be differences among species and populations using different migratory routes. For instance, previous meta-analyses have suggested that shorebirds using the Mid-Continental Flyway are experiencing more rapid declines than those using the Pacific or Atlantic flyways (Thomas et al. 2006). At the same time, within a species, more northerly breeding populations are experiencing greater phenological mismatches and lower reproductive success than southerly ones (Kwon et...

The Yukon-Kuskokwim Delta (YKD) Aerial Breeding Pair Survey provides data on the spring abundance of targeted waterfowl species nesting on the YKD coastal zone in western Alaska. This region supports millions of waterbirds that comprise one of the largest and most important waterfowl breeding grounds in North America, including species of concern such as the red-throated loon (Gavia stellata), emperor goose (Chen canagica), Pacific black brant (Branta bernicla nigricans), common eider (Somateria mollissima), black scoter (Melanitta nigra), long-tailed duck (Clangula hyemalis), and the threatened spectacled eider (Somateria fischeri). The YKD goose, swan, and crane survey was first implemented in 1985 to monitor...

This collection contains the quality-control (QC) transcribed data from the Yukon-Kuskokwim Delta Aerial Breeding Pair Survey. These QC data were produced from the “raw” data using the R Package “AKaerial.” The raw data were evaluated against the current data standards in the ‘AKaerial data dictionary’ and saved to new QC data files with associated log files that document any changes that were made. From 1985 to 1997, observers recorded bird observations out to 200 meters from the aircraft using continuously running tape players (with a locational accuracy of +/- 5 km), while an automated voice recording survey program (with a spatial accuracy of +/- 0.5 km) was used to record data from 1998 to present. The data...
