Scripts to Analyze Altitude Selection in Migrating Pacific Flyway Geese
January 16, 2024
This code repo contains three scripts used in the associated manuscript to run the analyses (01_model_prob_flight.r; 02_model_altitude_selection.r) and the simulation used to make predictions (03_simulate_prob_fly_per_altitude.r). The analysis serves to evaluate conditions that affect 1) whether geese are in flight vs. resting on the water, 2) what altitude is selected by flying geese, and 3) what proportion of locations are expected to be at various altitudes under various conditions. This analysis was developed to evaluate how often, and under what conditions, geese migrating over the northeast Pacific Ocean fly at altitudes coinciding with the rotor-swept zone of offshore wind turbines.

Geese migrating over the Pacific Ocean select altitudes coinciding with offshore wind turbine blades
Renewable energy facilities are a key part of mitigating climate change, but can pose threats to wild birds and bats, most often through collisions with infrastructure. Understanding collision risk and the factors affecting it can help minimize impacts on wild populations. For wind turbines, flight altitude is a major factor influencing collision risk, and altitude-selection analyses can evaluate
