Rook looking for food

I love watching rooks. They are so funny when they are looking for food. It would seem that autumn is food for birds. The insects have not hibernated yet. And how many seeds of different plants are now. But rooks still envy when another bird starts looking for food next to them. In my video, a lonely boat in search of food. Rooks still feed and bury them in different places. Perhaps this rook is looking for the food it has hidden earlier. Therefore, I drove the daw.
