Amentos de roble y reinitas gorjinaranja: consumo oportunista de flores por un ave insectívora
Keywords:
Reinita Gorjinaranja, aves migratorias, conducta oportunista, consumo de flores, Andes colombianosAbstract
Se ha documentado que la dieta de la Reinita Gorjinaranja (Dendroica fusca) incluye insectos y ocasionalmente frutos. Registramos a esta especie consumiendo flores de robles (Quercus humboldtii) en los Andes colombianos, aparentemente una respuesta oportunista a un recurso temporalmente superabundante. Conductas oportunistas de este tipo han sido registradas para otros migratorios boreales en sus zonas de invernada. Reseñamos brevemente el efecto del consumo de flores para la planta y los posibles beneficios para el ave.
