Imagine what seagulls usually call and pose.
Relaxing in front of the old man, seeing the old man coming to give them food, the seagulls formed a neat team, "brushed" and pounced on the old man and ate the food scattered by the old man. When you are full, you "snuggle" in the old man's arms like a child. There is lying, standing, and "golden rooster independence", which is very comfortable. Seagulls make a soft "O-O-" sound.
