Non-game bird biologist John Castrale, right, and assistant bird biologist Amy Kearns, both of the Indiana Department of Natural Resources, examine a peregrine falcon chick at the Duke Energy Gallagher Station plant in New Albany on Wednesday morning. The Indiana DNR maintains a nesting box for the birds on one of the plant's stacks, which is similar to the cliffs where they instinctually nest in the wild. Three chicks recently hatched and the biologists brought them down to band them for identification and assess their general health. Peregrine falcons are endangered in the state of Indiana, but they are no longer on the federal list of threatened and endangered species in the United States.
