The Philippine Eagle (Pithecophaga jefferyi) is a critically endangered eagle species endemic to the forests of the Philippines.
The Philippine Eagle was discovered British naturalist John Whitehead in 1896 and was named after his father Jeffery Whitehead. The bird was originally called Monkey-eating Eagle, due to the previous belief that the eagle exclusively preyed on monkeys, hence the generic name Pithecophaga.
On July 15, 1995, Fidel V. Ramos, then President of the Philippines, signed Proclamation No. 615, declaring the Philippine eagle as the national bird.
