MEGA Unboxing Flock, Rook Requiem. Pebbles and Birds on Birds

About Birds on Birds, from BoardGameGeek:

One tree. A bunch of birds. What could go wrong? Find out in this light-hearted soirée of balancing adorably difficult birds for one to four players. Take turns selecting from your pools of oddly shaped birds, carefully balancing them on the rocking nesting tree. If the birds hold firm, you're in the clear. The higher you climb, the more you score! How to Play - Select a bird from your supply to place (with one hand only!) - Balance your bird on the tree (seriously, with just one hand! - Say, “Silly little squirrel, stay away from me!” - If no birds have fallen, you did it! Score your points and end your turn. - However – if any bird falls, add the fallen birds to your supply and end your turn. - First player to run out of birds or reach 20 points wins!
