Two bonus cards you can use in Songbirds. Shuffle teither the Owl or the Shrike into the rest of the Songbird cards during setup. Deal cards to each player and place the remaining one card aside, face-down. It will not be used in this round.
OWL: When you play the Owl from your hand, you must remove a Songbird card in the forest and place the Owl in that space. Then, place the Songbird card you have removed back into the forest using the standard placement rules. If you keep this card as your favored songbird, your score is 0.
SHRIKE: When played, swap the berries in the Shrike's row and column. Bird orthogonally adjacent to the Shrike are worth -1.
