As teenagers we would hold up french fries to let the seagulls take them. After a few freebies we would swat them with right hooks. Rats with feathers.
It is fun to watch them fly right behind the lobster boats.
The fisherman throw out the lobsters they can not keep either because of size or sex. The gulls will catch them right out of the air before they hit the water.
There is a restaurant on the Merrimack river in Newburyport, MA that has a huge wrap around deck overlooking the water. The gulls just sit there waiting for people to leave leftovers. Also, in the summer you will sea huge striped bass hanging out right around the deck. People will throw scraps for the fish to eat. Sometimes it becomes a fight for the food between a 3’ fish and a seagull.
I used to live near a lake 50 miles inland from the ocean. There was a flock of about 15 seagulls that lived on this lake that was only about 2 miles long. Late afternoon the birds would fly over to the neighboring towns open landfill and eat trash. Then they fly back just be dark to hang out on the lake. Eventually, they closed the landfill and the birds moved away. The problem was they stayed all year round even when the lake was frozen over. They were a menace.
Rats with wings.
