Lovely photos you've got there! Looks like a typical winter here in Estonia, except for this year. We just got our first snow of the year 4 days ago which is quite late. (But better than no snow at all, right?)
Bet the tree bark has a lot of yummy vitamins inside for 'em elks etc to consume.
Was there in mid-December a decade ago and there was snow, lovely place Tallinn is.
