A harpy eagle chick nestles in a laboratory at Panama's center for the protection of birds of prey in Panama City, Panama, April 23, 2002. [With talons three times more powerful than a Rottweiler's jaws and fierce enough to crush a human arm in a single movement, the harpy eagle is still too weak to survive deforestation, making it one of Latin America's most threatened birds of prey. Fearful that the harpy eagle soon will become extinct, the U.S-based World Center for Birds of Prey has set up a leading center in Panama to breed them in captivity and later release them in greater numbers into the wild.]
