Load the other raptors :)

Also Mostert Kriek suggests you upload your grey bird two frames back from this on Flickr. Possibly a flycatcher or is that the "possible sparrow" we all discussed a while back.

Hi Trevor and all,

Yes I am well aware of all those intermediate ageing plumages.

One thing that I noticed in my reading last night is talk of wing formulas. Much like with other families projection and length of certain feathers can help aid ID.

With both Tawny and Steppe the 7th primary is very long, not as long as primaries 1 through 6 but still longer than the rest.

This bird does not have that long 7th primary which means it cannot be either Steppe or Tawny. Apparently these formula work for all ages.

So even with the angle of the photo affecting perspective, the bird must be AHE as that is the only one left that fits.

I enjoyed the discussion, thanks for posting Dennis and Amanda!

Cheers,
Gordon

Take home messages from this very interesting and enlightening discussion:

Juvenile/immature raptors especially' brown jobs' are extremely difficult to identify.
Single view photographs are difficult to use for various technical reasons but often as in this case it is all we have
Jizz and overall shape of the raptor is extremely important
Field guides are exactly that and cannot cover all the possible plumage variations
Even the same species can vary in size,plumage and even bill size
Wherever possible look for a parent bird! In the past for me this is sometimes the only way to clinch the identity provided the bird in question is still dependent on it's parents.
In my experience juvenile or immature African Hawk Eagles seem to very variable and seem to give raptophiles many problems with identification
Time in the field spent looking closely at juvenile/immature birds of prey is the only really practical way to learn about these subtle variations. Books,illustrations and photographs will also help but are often confusing especially to novices but sometimes to the experienced as well
Be prepared to not be able to positively identify all birds of prey. Accept that on more than one occasion the view will be too fleeting or too distant.....or just too hard!
:D

Philip, I have to confess that I had lots of help from Etienne, Wildtuinman, and 4 or 5 other people who pointed me in the right direction. I started doubting the validity of the AHEagle id after another birder suggested otherwise, and on hindsight I should have trusted these guys who go out there every day and see these birds as part of their job.
Many thanks to all who responded :D

Hi All. Thank you to everybody who participated in this informative discussion. As a keen novice-birder I learnt a lot from all the comments. The most important insights were that: it is OK to have pictures of birds that cannot be identified unconditionally, and the shape, size, posture etc is as important as colour (good news for the colour-blind). Thank you again, the forum and its members are good for birding in SA
