If this card is in your hand or GY: You can Tribute 1 Beast, Beast-Warrior, or Winged Beast monster; Special Summon this card, but banish it when it leaves the field. You can banish 1 Level 4 or lower Beast, Beast-Warrior, or Winged Beast monster from your Deck; this card's name becomes that banished monster's name, also it becomes the same Type, Attribute and Level as that monster's, until the End Phase. You can only use each effect of "Cocatorium the Heavy Metal Avian" once per turn.
