Crows vs Gulls

An interesting encounter between Crows and Gulls. A mother Gull returned with food to feed her 2 young Gull's. She regurgetated the food onto the floor and the young ones began to eat it. As the mother left 3 crows began to move towards the food but the mother came back and flapped her wings around to scare off the Crows. She then left and the crows continued to go for the food, then the young Gull's mimmiced the mother's behaviour to scare off the Crows. The very intellegent crows know this behaviour, so it doesn't really scare them off and they continue to move towards the food.
