The national bird of the Philippines is the Philippine eagle (Pithecophaga jefferyi), known as the monkeyfish.

An excerpt from the article 24 facts about Philippines

The Philippine eagle is the largest of the eagles - the world's largest bird of prey. It is a species endemic to the forests of the Philippines, inhabiting the island of Luzon and the island of Mindanao, the provinces of Samar and Leyte. Its most numerous population is found in Mindanao (from 82 to 233 breeding pairs).

 It is a bird with beautiful long brown feathers on its head, forming a magnificent mane in the manner of an African lion. Its body length ranges from 86-102 cm and its weight from 4.5 to 8 kg. Its wingspan reaches 184-220 cm, and its beak length averages over 7 cm.

It is an endangered species, mainly because the Philippines has one of the highest deforestation rates in the world, and the eagle lives in forests.

The Philippine eagle has been the national animal of the Philippines since July 4, 1995.
