Biologists tag a male bobolink (Dolichonyx oryzivorus) in Nebraska. They will put tiny geolocators, which track sun intensity as well as sunrise and sunset, the birds’ backs. When the birds are recaptured (months from now) and the data is downloaded and used to calculate the birds’ migratory route. The species winters in South America, but little is known of its specific route.
