Biologist Chris Burnett throws a sturgeon back into the Hudson River north of the Tappan Zee bridge in Tarrytown, N.Y. Wednesday, May 28, 2014, after surgically implanting an electronic transmitter in the fish's belly. Scientists hope the tracking devices will allow them to track and study the federally endangered species to detect behavioral or adverse affects during construction of the new Tappan Zee bridge. While the sturgeon's life and reproductive cycle is complex, the fish spawns in the Hudson River in April and May. (AP Photo/Kathy Willens)
