The avril, a sizable predatory bird originally from the moon Yavin 8, possessed a coat of dense black plumage and small, beady eyes. Its wings stretched approximately eight meters across, and it brandished formidable talons measuring twenty centimeter in length. Furthermore, these birds could emit a piercing shriek that could damage an ear.
Being apex predators on Yavin 8, avrils hunted various species such as raiths, reels, and purellas; however, they particularly favored the offspring of the sentient Melodies.
