This file contains information pertaining to the survey plot including date and time of surveyed, survey conditions, plot location, and ecological and biological conditions of the survey plot. The data providers have invested considerable effort in QA/QC, but it is possible that undetected errors remain. It is strongly recommended that careful attention be paid to the contents of the metadata file associated with these data to evaluate data set limitations, restrictions or intended use. The originators of this dataset shall not be held liable for improper or incorrect use of the data described and/or contained herein. Potential users of these data should first contact the data authors listed below, as potential...

This file provides data pertaining to shorebird nests found on intensive plots. Each record pertains to a given nest, and contains information on species, location, number of eggs, chronology, and productivity.A portion of these data are available on ServCat (https://ecos.fws.gov/ServCat/Reference/Profile/57583).Much of these data have been published in Lyons, J.E., S.C. Brown, S.T. Saalfeld, J.A. Johnson, B.A. Andres, K.M. Sowl, R.E. Gill, Jr., B.J. McCaffery, L.R. Kidd, M. McGarvey, B. Winn, H.R. Gates, D.A. Granfors, and R.B. Lanctot. In press. Global importance of the Yukon-Kuskokwim Delta, Alaska, to breeding shorebirds. Ornithological Applications.These data do not represent all locations within the Yukon...

The Arctic_shorebird_egg_float_tool.xls was developed by Rob Rankin (updated in 2021 by Sarah Saalfeld) to estimate hatch dates, nest initiation dates, nest incubation dates, and nest age based on egg floatation equations developed by Liebezeit, J.R., P.A. Smith, R.B. Lanctot, H. Schekkerman, I. Tulp, S.J. Kendall, D.M. Tracy, R.J. Rodrigues, H. Meltofte, J.A. Robinson, C. Gratto-Trevor, B.J. Mccaffery, J. Morse & S.W. Zack. 2007. Assessing the development of shorebird eggs using the flotation method: species-specific and generalized regression models. Condor 109: 32-47.This tool can be found in the protocol folder.This tool provides species-specific estimates for 10 species: American Golden-Plover (AMGP), Dunlin...

The Pacific Flyway Winter Brant Survey (WBS) has been conducted annually since 1981 as part of a cooperative effort by the U.S. Fish and Wildlife Service, Canadian Wildlife Service, Mexico, and the Pacific U.S. states, to estimate the abundance of the Pacific black brant (Branta bernicla nigricans) in their principal wintering areas along the Pacific Coast (in Baja, Mexico, California, Oregon, Washington, British Columbia, and Alaska). The survey is conducted each winter in January-February by a composite of ground and aerial crews, with the Alaska portion being conducted by the Alaska Region of USFWS Migratory Bird Management. The primary objective of the Alaska survey component is to provide an annual index of...

This R code (YKDsalinity_QC.R) is used to process the raw legacy salinity data for fixed and random plots (2006 - 2019) and produce the quality controlled legacy salinity data for analysis and sharing (YKDsalinity_QC.csv). Basic operations include transforming missing value to a common code, transforming other variables to match the data dictionary, and cleaning spatial location issues. Of special note is that this QC process discover significant error in location data due to a variety of reasons so the random plot centers are added to the data table and should be used for analysis. The code requires the raw data (“Official_YKD.SALINITY.DATA.MASTER.2020.csv”), a definition of the nest plot study area (“NestPlotStudyAreaBoundary.geojson”),...

This is the YKD nest card data from 1985 to 2019 produced after processing with the R script "Nest_Cards_QC.R". This file ('Nest_Cards_1985_2019_QC.csv') should be used for producing population estimates and any other analyses. This file is what should generally be distributed for YKD nest card data requests.

This is the YKD egg observation data reformatted from the nest card data ('Nest_Cards_1985_2019_QC.csv'). The file eggs.R is used to produce this data set, and then this is further summarized into yearly stats on mean initiation and hatch dates to produce the file yearstats.csv.

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...

More than 90% of the Pacific population of Steller’s eider (Polysticta stelleri) spends a portion of the fall in Alaska during fall wing molt and staging period, mostly along the Alaska Peninsula. The long-term Steller’s eiders counts from fall emperor goose surveys have shown declines at Izembek Lagoon and Port Heiden and approximate stability at Seal Islands and Nelson Lagoon (1992-2015, USFWS unpubl. data). Spring surveys for Steller’s eiders have been conducted along the north side of the Alaska Peninsula by USFWS since 1992; fall oblique photographic surveys covering the same area began in 2012.Systematic transect-based “overhead” photography is a method proposed for the fall survey and will be used to generate...

Decide whether or not to fly the survey. This is a somewhat subjective call, but current and forecasted weather, especially ceiling height and cloud density, visibility, wind and rain are the main components that go into making that decision. Wind >15kts, ceiling <2,000ft, steady rain or visibility <5 mi generally results in a “no go” for flying the survey at that time. If any of these conditions are forecasted in the following 4-6 hrs, also generally calls for waiting for better conditions or forecasts.If a survey is a “go”, the survey aircraft departs Nelson Lagoon airstrip and flies east toward transect number 1. All photographic gear, cameras, computers, screens have been previously set up and software tested....
