Jon, came to this conclusion from all illustrations and pics I could find of jub Crowned showing barring on the back of the neck. I could be wrong to use this as an ID feature...

Lovely martial Jen. I saw one at Spier, and it was the same.

...some individuals certainly shows some mottling on the crown/back of head , which might take the form of barring. However , this area varies quite a bit on young crowned eagles and some are almost completely whiteheaded/-necked. So yes , they can show that character but some (many?) don't.

I think the all-white body rules out african fish eagle , RJ! This bird looks like an immature martial to me!

From my limited knowledge (at the moment!) (I am learning fast and furious :D )

Rusty and Jol

Any chance of that bird being, rather than Imm Martial, the pale form of Whalbergs Eagle? The marshal has a dark beak, whereas the bird in the pic has a yellow beak. Further advances on this?

....well , as I’ve said before , I’m not that experienced with wahlberg’s eagle , and given that it’s such a variable raptor , with plumages looking very much like this , it’s certainly a reasonable question , Scott. If you are indeed right that the cere (rather than the beak) is actually yellow , then you really have a good case , and since you have the original pictures , you’re definitely in the best position to judge.
However , I’ve tried to enhance the posted photo , and I’m not really convinced (yet) that it is actually yellow. I admit that it seems to have a slight beige/yellowish tint , but I suspect that it might be a result of the shrubbery in the foreground , which also causes discolouration in other parts of the photo – like on the lower parts of the greater coverts (also yellowish). Furthermore the gape , which should have approximately the same colour as the cere , certainly doesn’t look yellow to me , so maybe you could take another look at the original photo , and tell me if I'm wrong about this?

Any better to help you (and others) solve this one? Cropped, but untouched.

Bare part colouration seems to be the headline for these two mystery raptors – Scottm’s eagle and Haplo’s goshawk/eagle.

First one’s first: I’ve spent a bit of time looking through pictures of wahlberg’s eagle on the net , which isn’t as simple as it should be , since there are a lot of misidentified birds out there! However , after looking at the ones that I considered to be identified correctly , it seems obvious that wahlberg’s eagle has a bright yellow cere and gape regardless of age – this also fits the illustrations in various field guides. A close look on Scott’s photo shows that the bird doesn’t seem to have a bright yellow cere , and certainly no yellow on the gape at all! In fact , the more I look at the picture , the more convinced I become that what might seem like a faint yellowish cere , is actually a discolouration caused by the some out-of-focus twigs in the foreground. As mentioned earlier , this is also obvious in other parts of the picture , always causing a yellowish discolouration.
Since everything else seems to fit with martial eagle , I’ll stick with my first call on this one , but if anyone disagrees I’m all ears….!

Jon, thank you for your comprehensive and well-thought-through response, to both raptors. Aside from the learning experience you (and others have provided), let's just relegate my one to the unidentified folder, and move on to the next challenge and learning experience. :thumbs_up:

Hi Scott ,

My pleasure , I’m learning from this as well! In my opinion there is no need to “relegate” it to the “unidentified folder” though. Unless someone makes a really convincing case for another species , I think you can safely call this one an immature martial eagle - everything fits.
By the way , is it a dead bird on the branch in front of the eagle?
