The Black Dragonbird Feather is one of the many feathers that can be obtained in the Frontier. They are naturally obtained from the Black Dragonbird species, birds that are often seen resting in A Frontier of Dragons or Blackrock Mountain. It can be distinguished from other birds, especially from the Blackbirds, based on the fact that their feathers are red-tipped. The Black Dragonbird Feather can also be obtained from the Otherworld Tower.
In appearance, the Black Dragonbird Feather is a black feather with several pitch-black patterns spread all over the feather's vanes. Other than that, not much can be said about its appearance.
It is possible for players to exchange Black Dragonbird Feathers for gold during Slayer's Tasks if the task card is currently active. Besides that, the Black Dragonbird Feather can be sold to a selling vendor at a selling price of 18,000 gold.
