Here's another of those perplexing BBJs, altho deefstes' comments in the post immediately above does help a bit. This bird was quite a lot smaller than a tawny eagle (which I'd been observing earlier that morning), and my first guess would be dark morph booted eagle except for the apparent absence of those "landing lights". The other choice would be a smallish dark morph Wahlbergs. Unfortunately the "backlit" position didn't help with my photos :roll: I saw this bird in KNP in a tree overhanging the H7 on 12 October 2008.

Hi arks,

The dark chocolaty brown colour and the slight hint of a crest suggests this is Wahlberg's Eagle.

Hi Arks,

Definately a Wahlberg's Eagle! :thumbs_up: .....Booted Eagle should show the 'landing lights' & shouldn't show the crest on the head, and should also have an unmarked tail I believe.

Hi all... Many pics still to "process" from the Ratpack trip. I've already called this as the dark form of Wahlberg's Eagle (narrow tail in flight along with lighter spots on outer wing), but would appreciate your confirmation of it? Seen in vicinity of Satara, unfortunately with difficult lighting conditions:

Thanks!

Overcast days is a capital B when it comes to flight shots!

The straight leading and trailing wing-edges nicely parallel... yes, I confirm (MHO)

I know that this one is likely impossible to ID from these photos, but then again, it never hurts to ask? :tongue: My guess would be possibly dark morph Wahlbergs? Seen on 12 October 2008 along the western portion of the S145. I actual saw the(se) bird(s) twice, on the 10th, when there was a pair of birds in this tree, the one on the nest and a mate, and again on the 12th, when only the bird on the nest was there. Neither bird ever gave me a clear view on either day, but at least the sun was in the west on the 12th (whereas on the morning of the 10th, the sun was in the east, so the birds and tree were backlit :roll: )

@arks:
Your Eagle might be unidentifiable but there is one thing I thought I'd point out which was staring you in the face, although you might have missed it.

The bird is sitting on a nest. That holds a huge clue :wink: It rules out everything but Tawny Eagle and Wahlberg's Eagle. But yes, that puts us at the same spot we've been so often on this thread and we know by now that separating these two is not a trivial task.

It's probably a Wahlberg's Eagle. I'm saying this as the overall colouration seems to be mostly uniform (compared to Tawny which always show some mottling or streaking or whatever two-tone pattern you can think of). The shape of the head and bill should be usable in the ID but I can't seem to really get a feel for it on these pics.

Thanks, deefstes, that's very interesting about the eagle being on a nest. Don't other (BBJ) eagles have nests? :shock: I had no idea. I also should have mentioned that I did not think it was a tawny eagle because they were on the small(er) size. As for not even trying to ID a distant BBJ, I guess because my RSA birding opportunities are so relatively few, I always try, just on the off chance that ID might be possible :wink: And even if you're not confident of the Wahlberg's ID, I've learned something valuable, so I'm glad that I asked :tongue: :wink: Thanks for yet again adding to my knowledge, I really do appreciate all the help I get here and the confidence your help gives me!

The "clue" in nesting that deefstes refers to is that of all the BBJs only the Tawny and Wahlberg's eagles breed in the area you indicated the observation to have been made. The other BBJs are non-breeding migrants.

Is anyone willing to ID this raptor, seen in KNP this past weekend. Silly bird would not come out into the open for better pics :twisted: It was being dive bombed by a very angry fork tailed drongo

Looks like a tawny eagle to me Pjw.

I'd go for Wahlberg's Eagle on the first bird.
