Description
This is a medium-sized eagle, about 60 cm in length and with a wingspan of 150cm. Its head and wing coverts are pale brown and contrast with the generally dark plumage. The head and bill are small for an eagle. There is usually a white patch on the upperwings, and even adults retain a clear-marked white V on the rump; the wing markings are absent and the white V is not well-defined in the Greater Spotted Eagle. The Indian Spotted Eagle is entirely allopatric.
The juvenile has less contrast in the wings, but the remiges bear prominent white spots. It differs from Greater Spotted Eagle juveniles by a lack of wing covert spotting and the presence of a cream-colored neck patch.
The call is a dog-like yip.

Systematics, taxonomy and evolution
The birds formerly considered to be the resident Indian subspecies are now considered a separate species, the Indian Spotted Eagle (Aquila hastata), quite distinct and readily separable by morphological, behavioral, ecological and DNA sequence data. The European taxon is actually closer to the Greater Spotted Eagle; their common ancestor seems to have diverged around the middle Pliocene, perhaps some 3.6 million years ago (mya)[1], from the ancestors of the Indian birds. The "proto-Spotted Eagle" probably lived in the general region of Afghanistan, being split into a northern and a southern lineage when both glaciers and deserts advanced in Central Asia as the last ice age began. The northern lineage subsequently separated into the eastern (Greater) and western (Lesser) species of today, probably around the Pliocene-Pleistocene boundary not quite 2 mya.[2]
The spotted eagles as a group are quite distinct from the typical members of Aquila, the "true eagles".
The present species hybridizes occasionally with the Greater Spotted Eagle. Hybrid birds are almost impossible to identify if not seen from up close.[3]

Distribution and ecology
The Lesser Spotted Eagle breeds in Central and Eastern Europe and southeastward to Turkey, and winters in Africa. This is a very wary species of open or lightly wooded country, in which it hunts small mammals and similar terrestrial prey. This eagle lays 1-3 white buff-spotted eggs in a tree nest. As usual for eagles, only in breeding seasons with very abundant prey does more than one young fledge however: the female starts incubating when the first egg has been laid, and thus the first young to hatch usually outgrows its clutchmate(s) and will kill and even eat them sooner or later.

Tawny has an oval shaped nostril. But Wahlberg's has a round nostril as is the case with a Lesser-Spotted Eagle.

To distinguish the two of them confronted with a tough angle view on it which obscures the other tell tale signs, one would have to look closely at the eye color as well as the tarsi covering. A Wahlberg's has a brown eye as opposed to a the yellow'ish eye of an adult Lesser-Spotted Eagle. The tarsi of a Lesser-Spotted Eagle is also more stove-pipe like.

Do you have a picture of the legs of the bird for us perhaps, Jumbo?

The eye colour is a way to differentiate between a Lesser Spotted and a Wahlberg's…but it only helps you with adult birds….only the adult Lesser Spotted Eagle has yellow eyes.

I unfortunately only have shots of the back ….cannot see the legs….but there are a few other features you can use to differentiate between the two …the most distinctive being (for immature LSE): “white bases to primaries, white edging to coverts and secondaries, a white, U-shaped crescent formed by the uppertail coverts, sometimes have a white patch on the back” (SASOL 3rd edition). If anything, the bird in my photos can rather be confused with a juvenile Steppe Eagle…but then the round shape of the nostrils excludes a Steppe.

Maybe I should start by explaining that I am not disputing the id.

I have never seen this bird in the field before and like I have mentioned that if this bird was to be seen from a more tougher angle to make an id from, the legs would seem to be the target area for identification. I am making notes as to what to look out for as this bird does have a lot of similarities with the Wahlberg's Eagle.

SASOL III for instance mentions that there is no crest present at the Lesser-Spotted Eagle, but you picture shows the head with ruffled head feathers which inexperienced birders might confuse as a crest (I have too in the past).

I think this bird of yours could've fooled quite a few people into thinking that it was a Wahlberg's eagle from a front angle.
