A female bobolink (Dolichonyx oryzivorus) is caught by biologists using a mist net, near Wood River, Nebraska. Avian ecologists trap and put tiny geolocators, which track sun intensity as well as sunrise and sunset, on male bobolinks. 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.

Thousands of sandhill cranes (Grus canadensis) roost on the Platte River during their annual migratory stopover at the Rowe Audubon Sanctuary near Gibbon, NE. With water in the river fully appropriated for urban areas and agriculture, many wonder how long it will be until the river runs dry. Some 600,000 to 800,000 cranes use just a few miles of the river in central Nebraska–areas that have been been mechanically cleared of the woody vegetation that the birds can’t tolerate.
