Broad scale banding of midcontinent greater white-fronted geese (MCWFG) is motivated by the Flyway Management Plan objective to maintain optimum harvest opportunity throughout the population range (Central, Mississippi, and Pacific Flyway Councils, 2023). This objective is accomplished by implementing a harvest strategy whereby changes to bag limits and season dates are dependent upon thresholds of abundance and harvest rate. Such estimates are calculated through Lincoln estimation (Lincoln 1930, Alisauskas et al. 2009, Dooley 2023) that requires annual banding. In addition, banding provides a means to identify changes in harvest distribution. The U.S. Fish and Wildlife Service (USFWS) Migratory Bird Management...

This dataset, AirSum.csv, contains the raw transcribed bird and marine mammal data collected during the 1997-2002 aerial summer Southeast Alaska Nearshore Waterbird Survey. Note that this dataset contains records of species that were omitted in the final, quality-controlled data (SummerSimplified.csv), due to detection issues or inappropriateness of the survey design for those species.

The daily flight tracks of the 1997-2002 aerial summer Southeast Alaska Nearshore Waterbird Survey were recorded to an onboard computer using the custom survey software RECORD (John I. Hodges, FWS-MBM-Alaska, retired). The tracks were recorded by capturing the plane’s location from a GPS every five seconds as long as the software was running. The software was started at some time between the aircraft’s engine start and the start of the survey, and was shut down at some time between the end of the survey and engine shut-down. The tracks thus include the aircraft’s flight to and from the airport base. The 29 track files are named TRMMDDYY_AIR.csv, where MM = month, DD = day, and YY = year.

The Alaska Trumpeter Swan Survey used U.S. Geological Survey (USGS) 1:63,360 scale quadrangle maps as sampling units (plots). USGS identifies each 1:63,360 map with a combination of two identifiers: 1) the 1:250,000 quadrangle in which it occurs, and 2) the 1:63,360 quadrangle map itself. Similarly, in the swan survey files, the 1:63,360 map is identified by the combination of the “Map” and “Quad” fields. The Map field identifies the 1:250,000 quad by its USGS numeric code; the Quad field identifies the 1:63.360 map by its appropriate letter-number. USGS_Map_Index.tif is a map version of the USGS map index, saved in an image format (.tif).

This multi-layer GeoPackage contains the Alaska Arctic Coastal Plain Aerial Breeding Pair Survey design transects from 2007 to present. The original transects were created as shapefiles and imported to this SQLite database. Transects were saved as individual polylines named according to the year they were created (e.g., “main.ACP_2007_Trans,” “main.ACP_2008_Trans,” “main.ACP_2009_Trans,” etc.). These aerial transects were developed systematically from randomly-selected start points and created along constant lines of latitude. The inter-transect spacing in the low, medium, high, and very-high density strata varies so that areas with higher waterfowl density are surveyed more intensively. The current four-year rotating...

This collection contains the quality-control (QC) transcribed data from the Arctic Coastal Plain 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. The data files in this collection were named using the following naming convention: ACP_YYYY_QCObs_OOOO, where ACP=Arctic Coastal Plain, YYYY=Year, QCObs=Quality control observations, and OOOO=observer’s first initial and last name. These data contain known errors. These data should not be used except as raw input for...

R code that takes in the nest capture history data (chdata.csv), reformats it for model fitting in the Bayesian MCMC software JAGS via the R package jagsUI. Various generalized linear mixed models are fit using a Huggins two occasion capture history model structure as in Program Mark. A series of models of increasing complexity are fit and compared using DIC. Model text is written to text files for each model but is generally not used or saved. Posteriors are saved as Rworkspaces or written to text files for use in population estimation (nostpop.R). Code can be run to generate model results and R workspaces/objects to inspect parameter estimates. The primary purpose of this code is to compare various mixed model...

This project aims to estimate spatial and temporal trends of waterfowl and waterbirds on the Arctic Coastal Plain (ACP) of Alaska from 2007 to present. The main approach is motivated by Amundson et al. (2019) using space-time generalized additive models (GAMs, Wood 2017) but with some improvements to handle observer effects and to associate sampling effort to specific spatial locations along a sampled transect similar to Miller et al. (2013). As part of this effort, a major data quality control process was begun in March 2022 that led to the correction of many data errors and re-formatting of the original 2007 to 2023 data to make it more accessible and usable to outside partners (original raw data available here)....

Collection of photographs taken during PRISM field work on the Arctic National Wildlife Refuge. Photos include those taken of habitat within rapid survey plots (usually taken at the northwest corner of the rapid survey plot boundary), completed datasheets, and by crew members. Directories include ANWR_PRISM_plot_photos, ANWR_PRISM_datasheet_photos, ANWR_PRISM_other_photos. These data do not represent all locations within the Arctic National Wildlife Refuge where specific avian species may be present, as surveys only occurred in discrete survey plots. Additionally, individual birds may have went undetected within survey plots, as detectability was likely less than 100%, and is a function of many variables, including...

Many North American shorebird species are experiencing significant population declines, but we have incomplete information about the population sizes and trends for most species. Conservation efforts are underway throughout the Hemisphere to reverse these declines, but we cannot measure the success of those efforts until we have an accurate assessment of population sizes and trends. The Program for Regional and International Shorebird Monitoring (PRISM) is a broad-scale, multi-national effort to monitor both the sizes and trends of shorebird populations (https://www.shorebirdplan.org/science/program-for-regional-and-international-shorebird-monitoring/). PRISM also strives to describe the distribution and habitat...
