They live all over Ireland, but they tend to live near places that are close to water, such as Dublin. There are always lots of seagulls flying around the Dublin canal, just a few blocks from St. Stephen Greens park.
Seagulls tend to eat food from what people have dropped when they walk around Dublin, or they will monitor a person that they see carrying food and strike when the time is right, as they did with me. In Dublin, seagulls eat human food all the time. It's just part of their way of life. They've evolved to depend on humans for part of their food source.
There are plenty of seagulls, so there is no need to worry about their population. You're guaranteed to see them every day in Ireland if you live along the coast, as I do. The only thing that can harm this creature is humans, which luckily I have not seen happen in my time here. I have seen people try to chase them off while people try to eat their food, but that is about it. Seagulls are here to stay in Ireland.
