MANILA, Philippines - Did you know that there are only about 400 pairs of Philippine Eagle left in the world?

Considered as one of the most astonishing bird species in the world for its beauty and ferocity, the Philippine eagle is now listed as "critically endangered" in the International Union for Conservation of Nature.

In lieu with their dwindling population, the Philippine Eagle Foundation (PEF), a non-profit organization that focuses on Philippine eagle survival formed a conservation breeding program - a system that breeds and re-introduces raptors to their natural habitat in efforts to prevent their extinction.

To date, the foundation has successfully produced 25 captive-bred eagles, including "Mindanao," which was adopted by Cebu Pacific on October 5. Part of the airline's commitment is to provide food and necessary veterinary care for "Mindanao."

PEF believes that saving the lives of the eagles is important because the health of our environment and quality of human life is linked. Therefore, it is necessary to learn about the Philippine eagle's life and its threats to survival.
