Where did passenger pigeons get their name?

The scientific name is 'Ectopistes migratorius. Ecto and is from the Latin Word 'outside' and 'piste' is Italian for 'trail.' It is translated as a 'wanderer' or one that goes off the trail. 'Migratorous' is Latin 'Migrare' meaning: 'to change location periodically.' The French used a more common name 'Pigeon de passage' or 'pigeon of passage' because of the huge size of the migratory flocks passing overhead.
