Just a couple of days ago, American kestrels at Duke Farms in Hillsborough, NJ received some jewelry that will help biologists learn more about their migration and annual whereabouts in an attempt to fill in important data gaps about their habits.
Female kestrels received a leg band and more importantly, a geolocator, that will record the sunrise and sunset each day, which will in turn, allow us to determine where in the world these kestrels are on any given day.
