Abstract:From 1975 to 1990 the feeding habits of the Antillean Euphonia (Euphonia musica) were studied in the Carite Forest located at Cayey, Puerto Rico. The species, usually found in the canopy of mature rain forest, is considered a mistletoe (Phoradendron spp.) specialist. The Antillean Euphonia is here reported feeding on eight additional species of plants and on arthropods. After Hurricane Hugo, the species showed foraging and feeding flexibility such as searching and gleaning for insects from the underside of leaves in the mid-canopy and shrub layer of the forest, and eating varied food items. Behavioral changes may have resulted from shortage of its usual food (mistletoe) in the forest canopy as a result of major habitat disturbance following the passage of the hurricane. /// De 1975 a 1990 se estudiaron los hábitos alimentarios del jilguero (Euphonia musica) en el Bosque de Carite localizado en Cayey, Puerto Rico. La especie, típica del docel de bosques pluviales maduros, es considerada un especialista de la fruta de la capitana (Phoradendron spp.). En éste trabajo se informa al ave, alimentarse de otras ocho especies de plantas y de artrópodos. Luego del huracán Hugo, el ave mostró gran flexibilidad en sus patrones de forrajeo y alimentación tales como el rebusque de insectos en la parte inferior de hojas de la capa media y arbustiva del bosque, e ingerir variados alimentos. Los cambios en conducta pueden ser el resultado de la escacez de su alimento usual (capitana) en el docel del bosque como resultado de disturbios en el hábitat posterior al paso del huracán.
