The source of the confusion is people thinking you were referring to the 5th image not the 4th one perhaps?
Sorry to all, because that is what I thought. My comment nr. 6 actually related to picture nr. 5.
And I must admit that just looking at the the thumbnail of picture nr.4 I thought that the bird looked ok for a Marsh Tit, mainly because the whitish cheeks seemed to reach far to the neck, therefore producing a Jizz that was better for Marsh than for Great Tit. But after reading the other comments and looking at the fullscreen picture, I saw the black "neck-ring", so I was glad I didnt wrote a comment after only looking at the tumbnail!
And I must admit, that I thought, the lark looked ok for Skylark: I could not make a positive ID (somehow this bird looked strange, but I thought it was due to the picture quality with much "JPEG-artefacts"), but I couldnt find much against Skylark. But after reading the comment by Rotherbirder, I noticed that he seems right regarding the bill.
But as the bird seems to have a weak streaked breast (especially the centre) for a Thekla, I hope someone finds the time to write more about this picture, so I can learn.
And more: when I saw my first Theklas, I got the following feeling: their crest reminded me of an extreme Skylark. When you think, a Skylark uses hairgel to get its crest look like a Crested Lark, the result is a Thekla Lark.
This helped me many times I saw a bird in SW-France or Spain: I imagined a Skylark using hairgel to erect its crest. And if the result looked like the bird I was watching, it was a Thekla. But if I couldnt imagine that a "cool" Skylark can manage to get a crest like that, the bird was a Crested.
