Gulls are in trouble in their natural spaces - and some species, such as herring gulls and lesser black-backed gulls are seeking refuge in coastal cities.

The herring gull was already on the list.

Five other seabirds were already on the list - the puffin, kittiwake, herring gull, roseate tern and arctic skua.

The study found that more than 51,000 pairs of herring gulls nesting at natural sites - rather than towns and cities - were lost during the reporting period, accounting for a 41% fall in the population.

NatureScot said avian flu had been confirmed in sandwich terns, common terns, kittiwakes, herring gulls, black-headed gulls and guillemots so far this year.
