R code that takes in the nest capture history data (chdata.csv), reformats it for model fitting in Program Mark via the R package RMark. A series of models of increasing complexity are fit and compared using AIC. Output is written to text files for each model but is generally not used or saved. Code can be run to generate model results and R workspaces/ object to inspect parameter estimates. The primary purpose of this code is to explore model structures for predicting detection and as an attempt to reproduce historically used parameter estimates in past nest plot reports (e.g., Fischer et al. 2017 and earlier). Results from ‘Model 7’ are most similar to detection estimates used in the past.

Dusky Canada geese (Branta canadensis occidentalis) comprise one of the smallest populations of geese in North America and their breeding range is limited to Prince William Sound, primarily the Copper River Delta, and Middleton Island, Alaska. The Alaska Region of Migratory Bird Management initiated an aerial breeding pair survey on the Copper River Delta in 1986 after reported declines in the abundance of dusky Canada geese on their nesting and wintering grounds. Since 2008, the Pacific Flyway Council uses results of the aerial breeding pair survey, together with Middleton Island ground counts conducted by the Alaska Department of Fish and Game, as a management index to determine optimal hunting regulations. Survey...

EstimatesTableWBPHS_20220125.csv is a table of bird abundance estimates by year and species, 1957-2021. It was produced by MBM-AK using AKaerial R code and the WBPHS_AK QC transcribed dataset. The date in the file name (format = YYYYMODA, where YYYY = year, MO = month, and DA = day) represents the date that the R code was run to produce the table. A data dictionary and details on analysis methods are provided from the R package AKaerial and are also available within that package, see https://github.com/USFWS/AKaerial.

This geopackage contains the density strata that were used to create the Alaska Arctic Coastal Plain Aerial Breeding Pair Survey four-year rotating panel design. This file was derived from a mid-1980’s ArcInfo coverage for the North Slope Eider Survey that was produced through the visual interpretation of 1:250,000-scale LANDSAT imagery and the known nesting density waterfowl in the area.

This data package contains location data collected by the Argos System (CLS America, Inc.) from satellite transmitters attached to 116 Lesser Yellowlegs captured at multiple sites across their breeding and nonbreeding range in North America, 2018-2021. The raw data were processed to accomplish two goals: 1) flag implausible location and 2) remove locations within Joint Base Elmendorf-Richardson (JBER) and Eielson Air Force Base boundaries. Removal of locations in military land boundaries is required due to federal guidelines by Department of Defense (DoD) Public Affairs office and DoD Partners in Flight. Due to data sharing constraints of participating agencies, not all the locations (i.e., latitude and longitude)...

This report communicates survey results to the Pacific Flyway Representative for incorporation into harvest management reports and regulatory processes. This memorandum also is shared widely with partners outside the USFWS. The major products are a memo, automatically generated from an R Quarto document, and 19 comma delimited table files, one for each management index and table in the memo.

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, BoatSum.csv, contains the bird and marine mammal data that was collected during boat-based surveys in the summers of 1997-2001 to double-sample portions of the aerial summer Southeast Alaska Nearshore Waterbird Survey.
thumbnail
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...
