Now the period of construction and insulation of rook's nests has come. Rooks around collecting various pieces of paper. This one stuffed his beak with them. Probably very pleased with this amount.
This rook found a large branch on the ground and is now thinking how to drag it onto a tree to build a nest. It is interesting to watch them as they throw branches on the ground to find the center of gravity.
Well, he found the center of gravity and grabbed a large branch from the ground. Apparently building a new nest. You need a lot of building material.
Now it will take off and climb up in a circle with this heavy branch.
This rook looks at me slyly and says, "Don't bother me to work, I have to build a nest."
And this one stands and looks around in case of danger. If there is a danger, then it makes a loud sound and all the rooks take off and climb a tree.
