Atlantic: Where Do Songbirds Go to Die?
In 2017, understanding of purple-martin migration took another leap forward thanks to archival GPS tags, which log birds’ locations down to just 10 meters, as opposed to geolocators’ several-hundred-kilometer margin of error. The research, led by Kevin Fraser at the University of Manitoba, showed that purple martins spend significant amounts of time on low-lying river sandbars in the Amazon. At this level of precision, specific conservation implications begin to emerge. Protecting this sandbar habitat, for example, could be key to maximizing purple martins’ winter survival.
