Wood warbler (Phylloscopus sibilatrix).
Reaches 12 centimeters He has lemon-yellow eyebrows and his chest is lemon-yellow, the back is greenish.
Eats flies and insects.
A very small bird. She was moving very fast on the thin branches of the bushes and trees.
And its color makes it almost unnoticeable in the green leaves.
I accidentally noticed a flock in a nearby park. It was difficult to shoot them, but I still managed to make a few frames.
