Title: Borneo raptor for ID
Post by Andrew on May 13^th, 2006, 9:02pm

I photographed this distant raptor one evening in Sukau, Borneo on May 5th 2006 - can anyone ID it please? It was in riverine habitat at low altitude, a partially forested area bit also lots of oil palm plantations.

The 2 most common raptors in the area were Crested serpent eagle and Lesser fish eagle. I suspect this is a Hawk eagle but thats about as far as I get.

TIA

Jerdon's Baza? It doesn't look quite right for Wallace's Hawk Eagle, too light in the belly.

Thanks for the suggestion Subbuteo. I had considered both and was actually more inclined to Wallace's Hawk Eagle having looked at the OBC images but I'm not sure.

I've been to Sukau a couple of times, a fantastic place and seen both species there. I am by no means an expert! There is a suggestion of a crest but both species have that. Now that I've looked on OBC, the Baza is a much slighter bird, this one is pretty hefty, I think you are right with Wallace's hawk Eagle.

Did you get a Storm's Stork? I saw most of the hornbill species (except Helmeted) at Kinabatangan. Any elephants around? Just missed seeing them both times I was there.

No Storm's Stork but Lesser adjutant and lots of elephants - check out my pbase site ;)

I confess that I often assign tricky Hawk-Eagles to "Changeable" Hawk-eagle because they must be the trickiest of all... !!
I've got Mackinnon and Phillips' Birds of Borneo,Sumatra, Java and Bali. Changeable is described as "large" 70 cm. Wallace's "smallish" 45cm, and Blyth's "large" 52 cm. Blyth's has a single, broad white subterminal bar and white tip.
Any idea of size, or a pic with the tail pattern ?
John ;D

John, thats all I got - it was getting quite dim and as for size, I would have put it on a par with Crested Serpent Eagle. I may have to decide its a 'don't know'.

It looks to me as if the right leg is unfeathered. If so, the other bird you might consider is Oriental Honey Buzzard, which can show a bit of a crest, and is similar in size to both Crested Serpent Eagle and Changeable Hawk Eagle.
