Willow tit or marsh tit (from Poland, August 12th, 2021? (1 Viewer)

[arodris]

Hi,

I have doubts with two birds from the Bialowieza area, in Poland. The first image corresponds to a bird photographied inside the Strict Reserve on August 12th (I apologize for the picture as the bird was partially hidden by vegetation), whereas the second picture was taken at the Wysokie Bagno area on August 13th.

I have doubts with both birds regarding willow or marsh tits. Can anyone help me with them?

Thanks

The right picture shows a diagnostic feature for marsh tit: the little white spot on the bill base.
The even coloured wing on the first picture is a relative feature for marsh tit. Willow tit has very often a pale panel in its wing.
