range of genus

These species have a flesh orbital ring and a rounded (in cross-section) upper mandible. They have ten rectrices and only three toes (absent first digit, or hallux).[3]

The African piculet has sometimes been included in this genus. It has only eight rectrices and four toes in a zygodactyl arrangement (a weak first digit). It differs from the Asian species in the plumage colour of the adult, but not in the plumage pattern, body anatomy or in habits.[4]

Species edit

The genus contains two species:[5]

Image Common name Scientific name Distribution
  Rufous piculet Sasia abnormis mainly Malaysia and Indonesia
  White-browed piculet Sasia ochracea mainland Southeast Asia
