Águila Monera Pithecophaga jefferyi

A huge and extremely rare raptor of lowland and montane forests. One of the largest eagles in the world, and the national bird of the Philippines. Dark brown above with pale feather edges, white underparts, a streaked shaggy crest and back of the neck, powerful yellow feet, a very thick silver-gray bill with a black tip, and black around the eye. Unmistakable if seen well perched. In flight, much broader-winged than other raptors. Voice is a descending, whistled “weeuuuu!” repeated at intervals.
