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.

Reportamos la observación de un macho de Loxigilla noctis en la isla de Barbados del 24 de mayo al 12 de junio de 2010, el tercer registro de esta especie en Barbados. Discutimos la relevancia de esta observación en el estado taxonómico de L. barbadensis y la pérdida evolutiva del dicromatismo sexual. 

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.
