Code, input data, and simulated spatiotemporal distributions and energetic profiles for a model of mallard and northern pintail migration across the Northern Hemisphere
These data and code were collected to support the development of a modeling framework that integrates local daily weather conditions and land cover with individual energetics and morphology to simulate mallard (Anas platyrhynchos) and northern pintail (Anas acuta) migration across the Northern Hemisphere.The simulated birds move across a discretized landscape of 20 by 20 mile nodes. Provided data and code allow for a model to simulate avian migration from September 1st, 2019, through December 31st, 2020. There are 6 zip files included in this data release. 1. MigrationModel_2023.zip contains the model code used to simulate bird movement. It requires the files NodeSpecificData_2019.txt and ENV_MAT.csv to function. 2. NodeSpecificData_2019.zip contains static landscape information for the terrestrial Northern Hemisphere. For each node, the file has information regarding land cover types and areas, forage quality and availability, and capability as breeding range. 3. ENV_MAT.zip contains daily averages for temperature, weather severity index, air density, snow depth, windspeed, and wind direction for each node throughout the study period. 4. mallardtelemetrydata.zip contains satellite telemetry data for mallards that were tagged in Louisiana in the winter of 2019/2020. These data were used to validate the model by comparing to simulated mallard movement. 5. N_ABUND_ALL.zip contains example output from the migration model. It has expected abundance of mallards and pintails in each node on each day of simulation. 6. BCTable_full.zip contains simulated predictions for the distribution of excess energy availability (represented as body condition) across all mallards and pintails in the Northern Hemisphere on each day of simulation.

Tracking Data for Northern Pintails (Anas acuta)
공공데이터포털
This data release includes 2 child items with tracking data for Northern Pintails, a duck species that, in Alaska, nests throughout the state and in adjacent regions of Russia and Canada. Child Item 1: "Argos Satellite Tracking Data for Northern Pintails (Anas acuta) - Processed Data" -- Quality-controlled data collected from Argos satellite transmitters. Child Item 2: "Argos Satellite Tracking Data for Northern Pintails (Anas acuta) - Raw Data" -- All raw data collected from Argos satellite transmitters, provided for completeness of the archive.

Mallard migration and regional movement timing, distance, and direction data, 2018–2020
공공데이터포털
The mallard (Anas platyrhynchos) is an abundant and wide-spread duck species that exhibits considerable variation in migratory behavior due to a relatively large body size and behavioral plasticity in habitat use. Understanding migration and other movements of mallards has societal interest in a wildlife management context because mallards are a preferred species of waterfowl by hunters and have the largest annual harvest of all duck species in the United States. We monitored juvenile mallards during autumn-winters 2018-2019 and 2019-2020 to determine factors associated with timing, distance, and direction of regional and migration movements during autumn-winter across the midcontinent of North America.
Tracking Data for Lesser Scaup (Aythya affinis)
공공데이터포털
These location data were collected from a free-ranging species of diving duck, the Lesser Scaup (Aythya affinis), using the Argos Satellite Telemetry System with platform transmitter terminals (PTTs) that were surgically implanted in ducks. Ducks were marked at two breeding areas: Yukon Flats National Wildlife Refuge in Alaska, USA at the northern extent of their distribution (66.51000 degrees N, -145.98556 degrees W) in 2012 and at Red Rock Lakes National Wildlife Refuge in Montana, USA at the southern extent of their distribution (44.63778 degrees N, -111.73694 degrees W) in 2009. These data can be downloaded from the Movebank repository (www.movebank.org) as an Excel (.csv), Google Earth (.kmz), or ESRI shapefile (study name "Tracking Data for Lesser Scaup (Aythya affinis)", study ID 1081716933, https://www.movebank.org/cms/webapp?gwt_fragment=page=studies,path=study1081716933).

Argos Satellite Tracking Data for Northern Pintails (Anas acuta) - Processed Data
공공데이터포털
This metadata document describes the data contained in the "Argos Processed Data" (Child Item 1) of this data release. This data release contains all data collected by the Argos System from 129 satellite transmitters attached to Northern Pintail ducks on their winter range in Japan, 2007-2009. The raw data were processed to accomplish two goals: flag implausible location estimates and decode raw sensor data. Three Comma Separate Value (CSV) tables are included in the "Argos Processed Data" (Child Item 1) of this data release: 1) the "diag_filteredLocations" table contains one record for every location estimate collected, accompanied by a binary flag that denotes an algorithm's plausibility check. Each record also includes a 'Tracking_Status' variable that denotes whether the location was collected from a live animal, a dead animal, or shed transmitter, 2) the "decodedSensor" table contains decoded sensor data such as a transmitter's temperature, battery voltage, and motion (activity), and 3) the "deploymentAttributes" table contains one record for each transmitter deployment in a CSV formatted table. The deployment attributes file contains information such as when the transmitter was attached to the animal, when tracking of a live animal ended, and a variety of variables describing the animal and transmitter. This table is identical to the "deploymentAttributes" table in the "Argos Raw Data" (Child Item 2) of this data release.

Movement Data for Migrating Geese Over the Northeast Pacific Ocean, 2018-2021
공공데이터포털
This dataset consists of one table with a record (row) for each goose location and columns containing location information and covariates. The dataset was used in an analysis of altitude selection and flight propensity in an accompanying paper (Weiser et al. 2024) and is being provided here to allow replication of that analysis. Goose locations (latitude, longitude, and altitude) were collected with GPS tags and represent three subspecies: Pacific Greater White-fronted Goose, Tule Greater White-fronted Goose, and Lesser Snow Goose. Covariates include weather information from ERA5 (Hersbach et al. 2022). In addition to the "used" locations (altitudes at which birds were recorded), the dataset also includes "available" locations: altitude bands that the bird could have reached by that time, given its previous altitude, elapsed time, and maximum climb rate.
