These tiny owls are 12.5 to 14.5 centimetres long and have a wingspan of about 27 cm. Their primary projection extends nearly past their tail. They have fairly long legs and often appear bow-legged. They can often be heard calling to one another just after dusk or at sunset. Their call is a high-pitched whinny or chuckle. The male and female dart around trees and call back and forth.
