As a rule, all titmouses are very mobile. It is very difficult to photograph them. In this photo, a titmouse is a blue tit. They are distinguished from ordinary tits by the presence of a blue cap on their heads and they are smaller in size.
She is looking for food on a tree trunk.
An ordinary titmouse flew to the feeder and looks to see if there is anything in the feeder. This feeder was hung up by some good Samaritan. At the bottom, he even attached a sheet of paper with the inscriptions what bird food can be put in this feeder.
The titmouse flew closer to the feeder, sits and examines the seeds in the feeder.
Now she flew into the feeder and decided to grab a seed for herself to eat.
