Résumé :	During the second half of the twentieth century, Green-winged Teal Anas carolinensis was almost universally treated as a subspecies of 'Common Teal'. Reassessment of morphological and behavioural differences between Green-winged Teal and Eurasian Teal A. crecca, together with molecular evidence regarding the phylogenetic relationships of Green-winged Teal, Eurasian Teal and Speckled Teal A. flavirostris, indicates that these taxa are best treated as separate species. The status of Green-winged Teal as a species can be justified under the Phylogenetic, Evolutionary and Biological Species Concepts. The basis for recognising A. c. nimia as a separate taxon is weak, but merits further study.
