Tower Birds, Former radar towers on Middleton Island, Alaska, serve as deluxe nest high-rises for black-legged kittiwakes. This form U.S. Airforce Base once monitored the skies for Soviet aircraft during the Cold War. Today it helps monitor birds. Biologists from the Institute for Seabird Research and Conservation converted the tower, so they could study the birds 24/7. Here, a parent returns to its chick after foraging at sea. Through controlled experiments, physical and behavioral monitoring, the birds are teaching researchers about responses to changing ocean conditions.
