馃憠The Eurasian treecreeper or common treecreeper (Certhia familiaris)
If you look closely at the photos, you can see the noise. The fact is that the photos were taken by me on a cloudy autumn day, that is, without a light source, moreover, it was in a forest filled with trees where light weakly penetrates through all this, and of course the bird itself moves very quickly through the tree. And not just from the bottom up, but its trajectory of movement in a spiral. And in order to take a photo of this bird, it is necessary to increase the ISO and the shutter speed on the camera.
The bird does not exist alone, it is a participant, which I have mentioned many times, a mixed bird of the flock. But their number is much smaller than, for example, nuthatches. Moving along the trunk of a tree, this bird searches for hidden insects, her long thin beak pulls them out like tweezers.
