Nocturnal foraging by artificial light in three Caribbean bird species

Main Article Content

Adolphe O. Debrot

Abstract: I discuss observations of opportunistic use of artificial light for feeding in the dark by the native White-tailed Nightjar (Caprimulgus cayennensis), the long-established Cattle Egret (Bubulcus ibis), and the introduced Carib Grackle (Quiscalus lugubris) in Curaçao, Dutch Caribbean. The observations demonstrate avian adaptability to anthropogenic ecosystem changes.

Resumen: Discuto las observaciones del uso oportunista de luz artificial para la alimentación nocturna por parte de una especie nativa, Caprimulgus cayennensis; una especie se ha establecida de modo natural, Bubulcus ibis; y Quiscalus lugubris que fue introducida en Curazao, en el Caribe holandés. Las observaciones demuestran la adaptabilidad de las aves a los cambios antropogénicos en los ecosistemas.

Résumé: Sont présentées ici des observations de l’utilisation opportuniste de la lumière artificielle par une espèce autochtone, l’Engoulevent coré (Caprimulgus cayennensis); une espèce allochtone présente depuis longtemps, le Héron garde-boeufs (Bubulcus ibis); et une espèce introduite, le Quiscale merle (Quiscalus lugubris), à Curaçao, Antilles néerlandaises. Les observations Adémontrent l’adaptabilité de ces espèces aux modifications des écosystèmes par l’homme.
