Subspecies

Genus Species subspecies Region Range
Nisaetus philippensis OR Luzon, Philippines

Genus

Nisaetus is a genus of eagles found mainly in tropical Asia. They were earlier placed within the genus Spizaetus but molecular studies show that the Old World representatives were closer to the genus Ictinaetus than to the New World Spizaetus (in the stricter sense). They are slender bodied, medium sized hawk-eagles with rounded wings, long feathered legs, barred wings, crests and usually adapted to forest habitats

Physical charateristics

Medium-sized eagle with longish, black crest. Rufescent-brown crown and face, streaked darker. Dark brown upperparts. Brown tail with 4-5 darker bars. White throat, bordered by dark malars. Black mesial stripe. Rufous underparts with black streaking. Finely barred black-and-white “trousers”. Pale iris. In flight, shows broad, rounded wings and well-barred flight feathers. Juvenile has white head and underparts, upperparts fringed paler. Acquires adult plumage over four years. Difficult to separate from Barred Honey-buzzard Pernis celebensis and Changeable Hawk-eagle Spizaetus cirrhatus unless seen well. Combination of long crest and feathered legs diagnostic.

Range

Oriental Region : Luzon, Philippines. Spizaetus philippensis is endemic to the Philippines, where there are records from c.60 sites on at least 12 islands. Since 1980, there have been records from 15 localities on Luzon (primarily in the Sierra Madre mountains), 13 on Mindanao and six on Mindoro, Bohol, Negros and possibly Panay, combined.

Habitat

It inhabits primary, selectively logged and disturbed forest, occasionally frequenting open areas, from the lowlands to lower mountain slopes, almost exclusively below 1,000 m. It appears not to tolerate much forest degradation. Perches in concealed locations in canopy and often soars

Reproduction

Conservation

This raptor qualifies as Vulnerable because its small, severely fragmented population is undergoing a continuing rapid decline owing to lowland forest loss, exacerbated by hunting and trade.
Deforestation for plantation agriculture, livestock and logging throughout its extensive, predominantly lowland range is the chief threat. In 1988, forest cover was as low as 24% on Luzon and 29% on Mindanao and these figures are likely to be overestimates, with most lowland forest leased to logging concessions. Habitat loss is exacerbated by considerable hunting and trapping pressure
Philippine Hawk-Eagle status Vulnerable

Migration

Non-migratory, but juveniles disperse from breeding areas
