The Philippine Eagle: Guardian of the Rainforest and a National Treasure

The Philippine Eagle (Pithecophaga jefferyi), also known as the “King of Birds” in the Philippines, is one of the rarest and most powerful raptors in the world. Endemic to the lush rainforests of the Philippines, this critically endangered species is not only a symbol of national pride but also a vital indicator of forest health. With a wingspan stretching up to 7 feet and a fierce, shaggy crest, this apex predator reigns supreme in its ecosystem.
Fun Fact: Despite its former nickname, the “Monkey-eating Eagle,” this bird actually has a diverse diet that includes flying lemurs, snakes, and even small deer!
