didine

The Raphinae are a subfamily of extinct flightless birds colloquially called didines or didine birds. They inhabited the Mascarene Islands of Mauritius and Rodrigues, but became extinct through hunting by humans and predation by introduced non-native mammals following human colonisation in the 1600s.This clade is part of the order Columbiformes and contains the monotypic genera Pezophaps and Raphus. The former contains the species Pezophaps solitaria (the Rodrigues Solitaire), the latter the Dodo, Raphus cucullatus. These birds reached an impressive size as a result of isolation on predatorless islands in accordance with Foster's rule.
