Legs

I agree a Chiffchaff from the very short primary projection. Interesting to note though how light the legs are and just goes to prove ‘dark legs’ are not a great field indicator.

Chiffchaff ?

Left hand bird shows pale legs, lack of obvious lower orbital and darker ear coverts, and strong yellow wash all of which point to willow warbler.

Juvenile willow warbler

Now that you point it out - I think young willow is the best match for the first image. The yellowish underside and strong yellow stripe over eye, flatter head than chiffchaff, pale legs, all fits.

The frame grab is at a slight angle which shortens the overall length/profile of the bird.

Willow

I agree with you, but the primary projection is definitely short. It could be a small, short-winged female Willow, but I don't think we shall know for sure, without the bird in hand. The juvenile is certainly a Chiffchaff, which is what I was agreeing with, above.

Wiilowchaff

I agree with Ian. The primary projection is very short (no amount of foreshortening can produce that amount of distortion) suggesting strongly chiff, all the other indicators mentioned are unreliable due to the amount of variation in both willow and chiff which creates a lot of overlap, although in this case they do lean towards willow. So another willowchaff then.

Willow

The new picture looks like a Willow Warbler; perhaps a small female, as said before.
