Report an ʻIo Sighting

The Hawaiian hawk is a medium-sized raptor with broad wings and a short tail. Adults typically measure 16-18 inches in length.

ʻIo have two color morphs: light (pale underparts with dark upperparts) and dark (entirely dark brown). Both morphs can occur in the same nest.

Look for soaring flight patterns, perching on tall trees or poles, and distinctive calls that sound like a high-pitched "eeeh-oh".
