Most of what we know about the eagles comes from studying eagle populations on Mindanao, in captivity or at known nesting sites, says Jayson Ibañez, research and conservation director at the Philippine Eagle Foundation[1] in Davao City. The Philippine Eagle Foundation was formed in 1987 to conserve eagles through captive breeding and has since expanded its mission to include scientific research, educational outreach, and culture-based resource management programs. Population figures—extrapolated based on the average distance between known nesting sites—are estimated at about 400 pairs, Ibañez says.

Philippine eagles, which weigh about 10 to 18 pounds and have wingspans averaging 6.5 feet, are excellent fliers. They propel themselves into the air with a few power flaps and then glide, Ibañez says. They ride on thermals, rising currents of hot air, then slowly spiral back to the earth.
