The best way to tell them apart is how they sound
marsh tit say a quick "che che" or "pitchju"
willow have a lazy " tjäääh tjäääh"
Both are there, it's not long from the former Linnulauluradio cam, it's the same good camera (stereo sound too?)
-
I had once read ( ) that marsh tits, unlike willow tits, have a bright spot at the base of the lower beak
here, with the left bird of the pair I believe to see the. what do you think?
A camera is a camera with it's own way of showing colours.
This one I think is a willow tit
Bright hind cheek and light wing panel
Again: best way to tell them apart is how they sound, turn up the volume to max
