So looking at those pics on the SANPArks forum, the bird is clearly a spotted Eagle. The only question now is are those dark eyes diagnostic for Greater Spotted or typical of the juvenile Lesser Spotted or is this a hybrid (recallilng the article saying how many intra african "greater spotted" are actually hybrids.

The mystery deepens. An Eagle with Stove pipe legs and an oval nostril. Is there such a thing?

Diet is wrong but if you have Raptors of the world, look at 4th year Vereauxx' eagle female and the flight shots on Sanparks site. How is that for a concept?

These were all captured from a video recorded at the sighting. Hope this help to clear up some doubts.

I am certainly not sure of exactly what it is.

Hi there,

I have just had the chance to really go through this thread and look at the photos closely.

I do not regard myself as being totally in tune with these large brown eagles as, being stuck down in the Cape most of the time, I do not get to see them very often. However, I will offer my opinion for what it is worth.

Firstly, I do not believe that this is one of the Spotted Eagles. The oval nostril and lack of obviously thin leggings would eliminate this immediately. Great Spotted should also be showing an obviously shaggy nape which this bird does not. I also feel that the bill is too sturdy for LSE and that the gape does not extend far enough back for that species either.

Of the other brown eagles, Wahlberg's and dark morph Booted can also be eliminated on size of the bill and overall structure, so we are really left with either Tawny or Steppe.

Everyone has stated that this bird has a dark eye, but to my mind, this is very much a pale eye?!! Looking at the gape, it barely reaches the middle of the eye, so that should eliminate both subspecies of Steppe that would possibly need to be considered.

This is also a young bird, so the paler nape patch and overall blotchiness of the plumage does not worry me too much as the younger birds never really show neat plumage.

So, to sum it all up, in my mind, this bird is a young dark Tawny Eagle. I spent a bit of time in the northern Kruger a couple of weeks ago watching a number of these young Tawnys feeding on the ground and they looked no different to this bird.

Use it. Don't use it. It's just my opinion...

Kind Regards
Trevor

HI Trevor.

Thanks for the comments. Do you recon that white showing through on the underwing as it is taking off is in keeping with a dark phase Tawny? Might that be some leucism comming through?

Cheers.
Doug.

I saw a number of other young Tawnys recently showing similar amounts of white on the underparts and the back. I have no references here with me at the moment, but it may be an artefact of them moulting from juvenile into immature plumages?

Regards
Trevor

Alot of white indeed! Taken this into account - I must agree with Trevor and start to lean towards Tawny Eagle.

The gape length was always a problem with Steppe (but I still would have gone with Steppe before the last photos).

The only problem with Tawny is the feathers on the lower leg, I still however doubt if this is a Spotted Eagle (either) - both of them has alot less white on the rump and under the wings.

If this is a Tawny and if Trevor saw many of them at termite erruptions in North Kruger, then Roberts need to be updated on the food preverance of Tawny Eagle as nothing is mentioned about Tawny eating any insects/termites. This is mentioned at Steppe and LSE.

Hanno,

Just a quick clarification - I never said that they were at termite erruptions.

In fact, I could not really work out what they were feeding on. We saw them foraging on the ground a number of times, sometimes in groups of 3 or 4 birds together, but could never see what they were foraging for. Also, the birds seen on the ground were always young birds and not adults.

Kind Regards
Trevor
