When people talk about “seagulls”, they are usually referring to the Herring Gull.
Herring Gulls have seen a huge decline in their populations in recent years and they are now considered an Amber-listed species of conservation concern. However, for several reasons, these birds are being seen and heard more frequently in urban areas, which may lead people to believe that there are more of them.
Traditionally, Herring Gulls would nest on islands but non-native predators such as rates and mink have become a threat to nesting birds and their young. As a result, Herring Gulls will now often choose safer nesting locations, such as high up spots in urban areas. Overfishing in Irish Waters has also left many gulls desperate for food, which often drives them into urban areas where they can scavenge from bins and other places.
Herring Gulls are very protective of their offspring and will make a lot of noise if a potential predator, including a human, approaches. These birds also tend to become particularly loud at the end of the breeding season when young gulls are calling to their parents for food
