Cornish Red Data (2009)

The descriptive text, below the map, is from the Cornish Red Data Book (2009). The map on this web page depicts the organisms distribution and shows the records made pre-2000 and those made since.

Sylvia curruca - Lesser Whitethroat

Range & Status

Palearctic; in Britain and Ireland 80,000 pairs (chiefly England), decreasing.

Regional Distribution

Cornwall: uncommon summer visitor and passage migrant. Odd pairs have bred annually since 1977 at scattered sites over Cornwall; prior to this there had only been three breeding records. Isles of Scilly: uncommon migrant, chiefly in autumn; one old breeding record (Tresco 1965).

Habitat & Ecology

Overgrown hedgerows and tall thickets, chiefly in coastal areas and along lower reaches of estuaries. A number of territory-holding birds recorded each year seem not to attract mates.


None known.


Listed (long list) as a globally threatened/declining species (BSGR, 1995).
