Филиппинская дронговая кукушка Surniculus velutinus

A slender, medium-sized bird of lowland and foothill forest. Entirely black with glossiness in the wing and in the slightly flared tail. Forages for insects in the forest canopy. Resembles Balicassiao and Hair-crested Drongos, but smaller, with a thinner bill and no fork in the tail. Song is a steadily rising series of whistled notes.
