Description

The Vava'u rail was a flightless bird with legs longer and bulkier than most known species in Hypotaenidia.[1] The bill was blood red becoming more of a pale pink towards the lip. The body had patches of grey and white appearing as a slaty blue. It was likely closely related, and visually similar to the ʻEua rail.[2]
