Gulls & Terns in Dorset
12 species matching this filter.
Dorset's diverse coastline, harbours, and estuaries provide outstanding habitat for gulls and terns, with 12 species recorded across the county. From the imposing Great Black-backed Gull patrolling Chesil Beach to the delicate Little Tern nesting on shingle shores, these seabirds are a defining feature of Dorset's coastal wildlife.
