3, 4 and 6 are Theklas, so your theory and logic prove correct. 3 is the "classic thekla" and so easier to identify, and although sat on a rock, it was actually in the middle of the steppe, and nowhere near high stony ground. You can see from just these few images how difficult they are to identify, made much worse when the bird refuses to sit still, or side on when in the field to enable the features to be seen clearly. I would love to see some work done on the DNA of both to see how much interbreeding actually occurs, i am sure there must be more than people would imagine. This appears to be one of the occasions when sceptics of bird identification via photos are proven wrong.
