Yellow warbler (Landschap de Liereman, Antwerp, Belgium, September 2017)

Hi, everyone! Got round to going through some of my older pictures and stumbled upon this bird, whose ID I never was entirely convinced with...

This bird is from the 2nd of September this year in Landschap de Liereman, in Northern Belgium.

I originally ID'd it as a willow warbler, but the rather odd head shape (semi)visible in the first picture make me doubt that original identification, and perhaps point more in the direction of a Hippolais species?

Unfortunately I wasn't able to get better pictures.

Looks Willow to me, but the pics aren't good enough to be definite

It's hard to put my finger on exactly why but this bird feels distinctly "Willow Warblerish" but I agree the photos preclude absolute certainty.

Okay, thanks for the help both of you!
