"In Society's Hands." Maryland schoolchildren were once taught that the bald eagle was on the verge of extinction. Pesticides like DDT were the main culprit. Then the Maryland Department of Natural Resources said bald eagles returned to the Chesapeake watershed in large numbers. Now, the bird's future may be endangered by something different, yet preventable: suburban sprawl and the loss of habitat.
"Osprey Heaven." This bird loves the Chesapeake Bay so much that now ospreys from Maryland are being caught and shipped to other areas where the species is in decline.
"Sharp Eyes, Red Shoulders." Maryland's population of red-shouldered hawks has dropped over the last 30 years in some parts of the state. That's why dedicated researcher Woody Martin still climbs to the upper branches of mature trees where these majestic raptors nest to measure the young that haven't yet left the nest.
