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 20,000 pairs (chiefly Wales and west Britain).
Cornwall: local summer visitor in small numbers to woodlands of east and mid Cornwall (currently one-five singing birds annually). Now difficult to find in upper reaches of Camel, Fowey, Lynher and Tamar valleys. Has undergone marked decline since 1960s, when 40-50 pairs were probably present. Exceptionally rare as a coastal migrant. Isles of Scilly: scarce migrant.
Habitat & Ecology
Mature broadleaved woodlands, with restricted understorey.
Destruction of ancient woodlands and subsequent replacement with conifers.
Protection of remaining woodlands. One site (Draynes Woods) is a NNR. Listed (long list) as a globally threatened/declining species (BSGR, 1995).
