European herring gull

The European herring gull is a sizable seabird found along northern and western European coastlines. While some migrate south in winter, others stay put year-round in places like Britain or Iceland. These adaptable birds eat everything from fish to scraps scavenged from humans.

• Grows up to 66 cm (26 in) long—about the size of a housecat.
• Will steal food from humans when given the chance.
• Some populations stay in the same area all year without migrating.
