How am I supposed to seperate those two in the picture below (they are adults of different species, so not a trick question)?

As I wish to avoid judging the relative robustness of the bill mark or the relative degree of paleness of primary edges, I'm--apparently--left with both a bill spot and a pale panel for the second bird in the picture from the paper (above).

The way I interpret the description, the clincher should be whether the wash on the side of the neck is (pale, cold/pale) grey-brown--often quite distinctly/frequently contrasts with the (clean) whitish ear coverts--or whitish or faint buff--usually doesn't abruptly contrast with the white cheek; frequently shows a subtle gradient between the ear coverts and the mantle; the warm buff suffusion on the neck can sharply contrast with the grey-brown mantle--considering that no Marsh Tits displayed warm buff tones to the neck sides.

While I wouldn't vouch for that feature being preserved after the adjustment of colour saturation, the above is what made me err towards Willow Tit for the second picture posted by the OP.

PS My lifelist is safe because I ticked both of them on call.

EDIT: The adult Willow Tit in the second picture from the paper (above) is ringed.
