Bird Power Colors

Brown (when activated) powers trigger every time you take that habitat's matching action, resolved right to left along the row. Pink (once between turns) powers trigger on a condition, usually during an opponent's turn, and at most once before your own next turn. White or uncoloured (when played) powers trigger only once, the instant you play that bird, and never again. Every bird power is optional — you may always choose to skip it.

With European: European adds teal round-end powers: they resolve after all turns of the round and before that round's goal is scored, and they do not trigger pink powers.

With Oceania: Oceania adds yellow game-end powers: each works once, after all end-of-round steps, in any order you choose.
