With their intense yellow eyes, herring gulls look quite agressive. Their downout brutal behavior contributes further to this poor image. They shamelessly steal bread from your hand and are seen as predators of young animals and eggs. However, it has never been proved that gulls are the cause of declining bird or other animal populations. What's more, they clean up lots of litter: ice cream cones that fall on the ground or french fries are gone in no time.
