The island of Mios Num is for a large part of the year uninhabited. The people of Pom, Woi and Woinap have gardens on the Island and only live there when they are harvesting. There are no sources (to my knowledge) that state Ansus speakers live there permanently. By the way, the Biak word for island is "mios", so maybe we should call the island "Num".
We will remove the reference to Miosnum island from the region description in our current database for these 3 languages.
