A rare observation of a male Lesser Antillean Bullfinch (Loxigilla noctis) on Barbados
Main Article Content
Abstract: We report the observation of a male Lesser Antillean Bullfinch (Loxigilla noctis) on the island of Barbados from 24 May to 12 June 2010, only the third record for this species on Barbados. We discuss the relevance of this observation to the taxonomic status of the Barbados Bullfinch (L. barbadensis) and the evolutionary loss of sexual dichromatism.
Keywords: Barbados, Loxigilla barbadensis, Loxigilla noctis, sexual dichromatism

Résumé: Une observation rare d’un Sporophile rouge-gorge (Loxigilla noctis) à la Barbade- Un Sporophile rouge-gorge (Loxigilla noctis), mâle a été observé à la Barbade entre le 24 Mai et le 12 Juin 2010, ce qui porte à trois le nombre d’observations de l’espèce sur cette île. Nous discutons de l’intérêt de cette observation en lien avec le statut taxonomique du Sporophile de la Barbade (L. barbadensis) et la perte du dichromatisme sexuel au cours de l’évolution de l’espèce.
