Accipiter virgatus (Besra)

Synonyms: Falco virgatus (homotypic)

Wikipedia Abstract

The besra (Accipiter virgatus) is a bird of prey in the family Accipitridae. The besra is a widespread resident breeder in dense forests throughout southern Asia, ranging from the Indian subcontinent eastwards across Southeast Asia and into East Asia. It nests in trees, building a new nest each year. It lays 2 to 5 eggs. This bird is a medium-sized raptor (29 to 36 cm) with short broad wings and a long tail, both adaptations to fast manoeuvring. The normal flight of this species is a characteristic "flap–flap–glide", and the barred underwings are a distinction from the shikra, A. badius.
