To complete a Flock you must reveal all Birds of that species in your hand; if the revealed number meets the small or big flock threshold you add one or two of those Birds to your collection and discard the rest, but you are never forced to complete a Flock and may choose not to (pages 6–7).

If a row contains only one species immediately after a player took cards from it, the dealer draws cards from the draw pile and adds them one by one (left or right) until the row contains two different species (page 5).

A round ends as soon as a player has no cards left in hand; all other players must discard any cards remaining in their hands while the center rows stay in place, and the player who emptied their hand becomes the next dealer and deals 8 cards to each player (page 8).
