Blue tit was peeking several of (likely) house sparrow nest boxes. These are recently moved to trees from site huts where house sparrows used them. Maybe the blue tit behavior was related to the event of felling trees - though there's some distance - as I heard similar behavior reported at earlier case from arborists falling trees who didn't know they were sparrow nest boxes there too.
