Brief Description

       Recently declared the national bird of the Philippines, the Philippine Eagle is found exclusively on 4 islands in the Philippines. Despite this, Philippine Eagle populations have sharply decline over the last three generations being reduced to an estimated 750 individuals maximum. Some more conservative population estimates put eagle populations as low as 250 individuals. in the wild.

      Philippine Eagles are monogamous and only breed every 2-5 years as they take a long time raising their young. In fact, their offspring tend to depend on adults for up to a year and a half! This long despondency period makes chisk highly vulnerable to predators and temperature changes. Below, you can watch the trailer for the Cornell film, Bird of Prey, which focuses on conservation and education efforts surrounding the Philippine Eagle exclusively.

       The Philippine Eagle is threatened by a variety of things, most significantly deforestation. They rely heavily on lowland forest to hunt and raise their young, but agricultural expansion is destroying much of this habitat. Commercial timber harvest has caused major fragmentation of populations with Old growth forests being cut down incredibly fast. Besides this, the eagle is also threatened by various traps, pesticide accumulation, and unregulated hunting.
