Columbicola extinctus, also known as the passenger pigeon chewing louse, is an extant species of phtilopterid louse. It was once believed to have become extinct with its only known host, the passenger pigeon (Ectopistes migratorius), prior to its rediscovery living on band-tailed pigeons (Patagioenas fasciata).
