The United Kingdom, with its extensive coastline and surrounding seas, provides a variety of habitats that support an impressive range of coastal and seabird species. These birds are not only vital to the health of marine and coastal ecosystems but also represent a significant part of the UK’s natural heritage. From the towering cliffs of Scotland to the tranquil estuaries of southern England, the UK’s coasts are home to colonies of seabirds that depend on the coastal environment for feeding, breeding, and migration. In this essay, we will explore at least 20 of the UK’s most notable coastal and seabird species, examining their habitats, behaviours, and conservation status.
