Animal movement and behavior

I contributed to analyses of citizen science occurrence data and GPS-tracked movement data to investigate animal movement behaviors.

• Altitudinal migration of birds: Using eBird data to characterize seasonal elevational movement, we found that the majority of resident birds in Taiwan shift elevation across seasons, likely driven by thermal tolerance and food availability (Tsai et al. 2021).
• Route navigation of carnivores: Analyzing GPS data from over 1,000 individuals across 34 species, we found distinct differences between wild cats and dogs in how they navigate their home ranges (Fagan et al. 2025).
