The English county of Dorset is noted for its expanses of heathland and coastal reedbeds. The combination of these nationally scarce habitats and a mild climate make Dorset a stronghold for some of Britain's rarest breeding birds. It also holds important seabird cliffs as well as several bird-rich estuaries and inland reservoirs. The county's rarity record is impressive. This county avifauna looks at the range and status of every species recorded in the county, using data gathered over many years by the Dorset Bird Club. A breakdown of all records for the rarities is also included.
