PHILIPPINE HAWK-EAGLE in Saray



One of this vulnerable hawk-eagle was transferred to Saray, Pakil, Laguna to secure to live and for hope, to multilply its species.



PHILIPPINE HAWK-EAGLE
Spizaetus philippensis
Critical —
Endangered —
Vulnerable A1c,d; A2c,d; C1; C2a

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.

DISTRIBUTION The Philippine Hawk-eagle is endemic to the Philippines where records
exist for at least 12 islands. A taxonomic revision of the species, separating birds on at least
Mindanao as a new subspecies, has recently been completed (Preleuthner and Gamauf 1998).
Records from Masbate and Lubang (McGregor 1909–1910) are unacceptable (Dickinson et
al. 1989, 1991), while an observation from Gaong valley, Sibuyan, March 1992 (Evans et al.
1993a), treated as provisional by Goodman  et al. (1995), has now been retracted (R. J.
Timmins in litt. 1997; see Remarks 1, also under Mindoro). There were several probable
sightings at Sibaliw, north-west peninsula, Panay, in August 1997 (D. Allen verbally 1997).
The records that follow have been accepted uncritically, and it needs to be stressed that there
are considerable identification problems with this species, so that all the available evidence
needs to be treated with a high degree of caution:
