Scientists have noted that Prothonotary Warbler populations have experienced precipitous declines in recent years, prompting new research investigating the little known migratory behavior of this remarkable bird. As part of this effort, researchers attached several geolocators -- ultra-lightweight devices that record the time of sunrise and sunset each day -- using a back-pack harness on several Prothonotary Warblers to identify their migratory routes and core wintering areas.
