Résumé :
|
The decline of the Red-billed Chough Pyrrhocorax pyrrhocorax across southern Britain was caused mainly by human activities, and resulted in its extinction as an English breeding species. Examination of the species' current status and feeding ecology in West Wales, and of habitat availability in Cornwall, is used to assess the feasibility of an assisted return to southwest England. Wild 'cliffscape', with plentiful earth exposure, is optimal habitat, especially if backed up by sympathetic pastoral agriculture. Extensive vacant habitat in Cornwall appears to be at least the equal of that which exists in Wales.
