Well guys , while we are all waiting for a better quality photo , here are some of my thoughts on this one:
From this picture alone , this bird certainly doesn’t look like an AHH to me! Imberbe is right that the bare facial skin can be difficult to see on a low quality photo like this one , but it contributes to that species pretty “gentle” facial expression. This bird however , has the typical fierce expression , with the piercing yellowish eye and prominent eyebrow , of the hawk eagles and “real” eagles.
It’s also true , as stated by Deestest , that juvenile AHE usually has a brown rather than yellowish iris , but there are exceptions to that rule , and anyway the colour changes towards yellow during the immature phases (I don’t see any evidence that this is a juvenile rather than an immature bird). AHH on the other hand has a dark iris in all ages , and this feature alone should rule out that species – I’ve never seen an AHH with a yellowish iris anyway!
Regarding the tarsus and foot , I agree with Lizet that it looks more eagle-like and to powerful for AHH , and the same can be said about the bill. I think it’s extremely difficult to see if the tarsus is bare (as in AHH) or lightly “feathered” (as in AHE) on this photo – the tibia is heavily feathered on both species by the way. The feathers on the tarsus of a AHE can be so short that it looks more like fur , and can be almost impossible to se – check this picture to see how much it can vary , even on the same bird (!): http://www.realbirder.com/NamibiaD/Bird ... kEagle.jpg
It’s true that the plumage isn’t to far of target for an AHH , but not really for AHE – and a number of other species for that matter – either. My initial concern – plumage wise – regarding AHE is the pale mottled back and wingcoverts. Normally young AHE’s show a pretty uniform dark brown upper side , but maybe this can be explained by moult , thus making it an immature bird for sure.
As I said , I feel confident that this is not an AHH , but I think it would be wise to wait for a better photo before concluding anything else for sure.
…and yes Ferdelance , this would be a good one for the Challenge , albeit with a better photo quality , and of course the quizmaster would have to know the answer…
