Nicobar Pigeon

“The Nicobar pigeon is the last of the Caloenas pigeons. Unlike other pigeons, Nicobar pigeons don’t fly in haphazard flocks but in columns or single file. The Nicobar pigeon is the extinct dodo’s closest living relative. Both of them are/were members of the Columbidae family. Many people are surprised that the ugly, flightless, turkey-sized dodo was a type of dove, but it was!”
