Hummingbird Fine Points

Hummingbirds count as birds for goals and bonus cards, and filled-columns goals count them. Empty hummingbird slots count for powers that count empty slots, but powers that use your leftmost empty slot ignore them. You never gain a track icon's action by moving down, and card powers that attract or return hummingbirds aren't limited to the current row. Optional: each player removes 1 action cube to keep the original game length.
