Vulnerable and protected Crested tit is one of the cutiest birds in Finland.
I was lucky to find these lovely birds as they are decreased due the lack of old forests.

One of the few European passerines with a distinct crest.
Back and wings greyish brown, underparts creamy white. Black bib and cheek markings,
crest dotted black and white. Crested tits are monogamous and will pair for life.
The females will excavate a hole in dead wood or use a nest box,
which they line with moss, lichens, and hair to create a nest.
