Marginalia

Proclaimed the national bird of the Philippines in 1995, it gave its Filipino name Haribon ('king of birds') to the country's leading conservation society. The first captive-bred chick, Pag-asa ('hope'), hatched in 1992.

Curiosity

Despite its old name 'monkey-eating eagle', its main prey on Mindanao is the colugo, a gliding mammal.
