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.
Range & Status
Palearctic; in Britain and Ireland 80,000 pairs (chiefly England), decreasing.
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.
Listed (long list) as a globally threatened/declining species (BSGR, 1995).
