What do all gulls have in common?

• A. They Are Scavengers
• B. They Nest in Evergreen Forests
• C. They Rely on Freshwater Fish Only
• D. They Migrate Only in Summer

Answer: (A)

Gulls are highly adaptable, opportunistic feeders, and scavenging is a common behavior among them. This means they readily eat garbage, food scraps, and carrion, as well as fish, invertebrates, and small animals they can find near coastlines, beaches, harbors, and even urban areas. Their ability to take advantage of a wide range of foods helps them live in varied environments, which is why scavenging sticks out as a shared trait.

Nesting in evergreen forests isn’t typical for gulls, since most make nests on coastal cliffs, rocky shores, or islands, or even on buildings in cities. Relying only on freshwater fish isn’t accurate either, because many gulls eat marine fish, squid, crustaceans, and other foods, not just freshwater sources. And not all gulls migrate only in summer—some stay in their range year-round, while others migrate long distances, so that pattern isn’t universal.
