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
Holarctic; in Britain and Ireland 160,000 pairs, but now declining.
Cornwall: local resident in coniferous plantations in the Bodmin Moor area; first recorded breeding at Davidstow in 1968 but now known to be present in small numbers at several other upland plantations, including those in the Wadebridge district. Numbers fluctuate but have possibly never exceeded 50 pairs, which are now in decline (perhaps ten pairs at most in 1993). Elsewhere an uncommon passage migrant: in winter sometimes encountered in Alders Alnus glutinosa during sporadic immigration influxes. Isles of Scilly: uncommon migrant, chiefly in autumn.
Habitat & Ecology
Breeds in conifer plantations, chiefly Sitka Spruce Picea sitchensis but also favours Birch Betula spp. Prefers young to mid-age plantations, forsakes sites as trees mature and become more densely enclosed. In winter prefers riverside Alders and Birches. Has colonised south-west England (where formerly absent) in the past 50 years, aided by post-war forestry planting.
As plantations mature and become very dense they become unsuitable for Redpolls.
Forestry management; mixed age plantations might allow the continued survival of the species in Cornwall. Listed (long list) as a globally threatened/declining species (BSGR, 1995).
