Declining seagull numbers

Researchers from UBC say the number of seagulls in the Strait of Georgia has plummeted and it could be because of what they’re eating.

A recent study shows the population of Glaucous-winged Gulls, the most common species of seagull in the region, has declined by half in the last three decades.

Lead author Louise Blight says the population decrease suggests profound changes in the area’s marine ecosystems.

She says fish and shellfish are becoming less available, and the birds have moved to a diet that incorporates food like garbage and earthworms.
