Wildfowl at risk, 1992

Abstract

Brief accounts are given of the status and causes of decline of 50 species and subspecies of wildfowl (Anseriformes) that are known to be threatened with extinction. A number of changes are made to the earlier list presented in this journal by Kear and Williams (1978), and each taxon is assigned a provisional category of threat in line with recent proposals for the re-evaluation of IUCN categories made by Mace and Lande (1991).
