THE MAJESTIC JAVAN hawk-eagle
used to glide unnoticed through the humid Javan rainforests, striking the dwindling landscape with dashes of colour from its rufous plumage and white-tipped black crest.
In this way, the identification of the feather as belonging to the black hawk-eagle
(Spizaetus tyrannus), was confirmed, with 99.68% and 99% top matches respectively.
Based on IUCN (2013) criteria, six listed species are threatened: one (White-shouldered Ibis) is Critically Endangered, another (Storm's Stork) is Endangered and four (Chinese Egret, Lesser Adjutant, Wallace's Hawk-Eagle
, Blue-banded Kingfisher) are Vulnerable.
"Birds of prey are one of the few things that some modern primates have special calls or alarms for." The killer has been identified as an African crowned eagle - also known as the crowned hawk-eagle
- which still preys on small primates.
Peering out the shooting window, I could see that an African hawk-eagle
had just trapped and killed a guinea fowl against the front of the blind.
