Summary

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 [...]

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.

Purpose

These data were created to facilitate the workflow of simulating waterfowl migration in response to daily changes in weather, habitat quality, and individual energetics (1). We provide the necessary inputs for simulation, including waterfowl-relevant habitat information (2) and dynamic daily environmental data (3). Simulation output examples (5, 6) can be used to assess expected spatiotemporal distributions and energy availability of waterfowl across the Northern Hemisphere. We used observed mallard migration (6) as a partial validation of the model by comparing simulated duck movement to observations.
