Like many seaside places Llandudno has many herring gulls. These are large, noisy birds. They aren't afraid of people and they are predatory. They seem to hang about looking for easy sources of food and yes, one stole my icecream cone and flew off with it! - Frightening!!
Jackdaws are the tamest of the crow family and like to live in close proximity to people. In the village where I grew up they built their nests in our chimney pots.
