Diet and Foraging

Diet

Diet consists of nectar and insects. They hold tubular flower corollas with their hooked upper mandibles and pierce through the flower with their pointed lower mandibles (Isler and Isler 1987). They take between 1 second in between flowers (Hilty 2011), and proceed to extract the nectar with their tongues. Due to this important behavior, they have been labeled as “nectar thieves” (Isler and Isler 1987). The foraging behavior can be seen at all heights, from near ground, and in very rare occasion on the ground itself, tops of shrubs and small trees. They can cling or hang down if the flower is out of reach (Hilty 2011). Typically forages for insects on foliage and in flowers, sometimes catching insects in aerial sorties. On some occasions, it may probe flowers directly without piercing the flower and, in rare occasions, have been found to contribute to pollination in Peru (Hilty 2011).
