During my Ph.D., I studied a range of South American migrants as part of a collaborative group called Aves Internacionales. Below are some short clips showing how different species track with seasonal temperature and rainfall patterns in South America (and one boreal migrant across both hemispheres). The points in the videos come from geolocator data collected by the collaborative group and the clips were put together by an undergraduate researcher in the Caz Lab at the time, Trey Hendrix. Thanks Trey!
