Boobries are birds first mentioned in Neverseen that make deafening roaring noises. They are described as black parrot-size birds with glittering dark eyes, a yellow feather mohawk, and long, curled eyelashes. Biana said that Fitz and Keefe make jokes about them all the time, because of their... peculiar... name.

In Lodestar, Sandor inspects a Prattles box containing a boobrie pin. He finds nothing wrong with it, and returns it to Sophie afterwards.
