The Philippine hawk-eagle or north Philippine hawk-eagle (Nisaetus philippensis), earlier treated under Spizaetus, is a species of bird of prey in the family Accipitridae. Many taxonomists consider the Pinsker's hawk-eagle, a former subspecies, raised to full species status. It is endemic to the Philippines. Its natural habitat is tropical moist lowland forests. It is threatened by habitat loss and trapping.
The Philippine hawk-eagle is a large raptor with a dark brown upper plumage and a pale brown belly. Head and chest are streaked and the lower belly is finely barred. The species has a conspicuous backwards crest. Juveniles are paler. The call a high, screeching "week wik!" or single "week!".
It was formerly conspecific with the Pinsker's hawk-eagle but has a shorter crest, larger size, browner plummage and plain markings on the belly. This split was supported by molecular analysis. In terms of size, it is a smaller eagle with a length of 56 to 67 cm, and a wingspan of 105 to 125 cm. One female weighed 1.16 kg.
This species is monotypic and has no subspecies. The first comprehensive study was conducted of a nesting pair... Wikipedia →

Rare
Under 5% of wildlife watchers report a Philippine Hawk-Eagle sighting in Manila on a given day, based on 111 verified sightings from GBIF citizen-science data. It is the 86th most-seen of the 191 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
February, April and June
In those months about 10% of wildlife watchers report a Philippine Hawk-Eagle in Manila on a given day, against under 5% in March, May and July–January, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Philippine Hawk-Eagle sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Manila, in our data
Manila is the only city on Wallace's Line with enough records to rate Philippine Hawk-Eagle sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Philippine Hawk-Eagle is recorded against all the birds logged in Manila (111 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
