The Avian Ecology & Biodiversity Research Lab (AEBRL) at Delaware State University (DSU) has played a global leadership role in the remote tracking of long-distance migratory songbirds. The AEBRL was the first to use light archival technology (geolocators) to successfully track forest songbirds through dense tropical forest understory of equatorial Amazonia (2011) and the first to use miniature GPS data loggers for the same purpose (2015). Our model species is Catharus fuscescens. The long-term study of the behavioral ecology of C. fuscescens at White Clay Creek State Park, Delaware, by Dr. Heckscher (AEBRL PI) has been continuous since 1998 and is among the longest running single-species songbird research projects in North America.
