Out of the 7,000+ islands that make up the Philippines the Philippine eagle is only found on four on them. At most they estimate there are only 750 mature eagles left, with the number being as low as 250. It is estimated that the island of Mindanao has the largest number at 82 to 233 pairs, six pairs on Samar, two on Leyte, and only a few on Luzon. They are critically endangered and numbers are currently decreasing, still. The fault? Us, humans. We are taking out their habitat (deforestation) forcing them to find new homes and they are running out of places. They are endemic to the Philippines and exist nowhere else in the world. Thankfully there are some efforts already in place to help these birds. Not only is there captive breeding programs, but acres upon acres of land protected for them. But, they still need more land than what we are currently providing. One pair needs 4,000 to 11,000 hectares (9,884 to 27,182 acres) depending on the amount of species in their area.
This poor eagle pictured above was shot dead. Deforestation is not the only thing decreasing the numbers. Typically farmers will shoot them to protect their livestock or even eat them! They never figured out who killed this one, but if caught you receive heavy fines and a 12 years prison sentence.
As stated above, the Philippine eagle is endemic to the Philippines and one of their top apex predators. Without them, populations of other species (their prey) would grow uncontrollably causing other populations to decrease. Eventually causing food shortages for species and possibly even humans.
