on the head

A white bird with a long beak is submerged in a small puddle of water in a grassy field, while a grey bird with a large, flat beak repeatedly pokes the white bird's head with its own beak. The grey bird's beak makes contact with the white bird's head, causing the white bird to react with a slight shift in its eyes and head position. The scene takes place in a grassy area with a line of trees in the background.
