4-6 3 Birds
Aim first red bird at edge of wood top of first house. Try to get middle and far monkey under platforms, but at least make sure to get middle monkey.
Arc second red bird to hit wood side of top square on middle tower. Best in fallout if the right wood side falls, to act as a buffer between the two towers, pushing far tower over to the left.
Arc third yellow bird to take out any remaining pigs and debris above far platform.
(This level can be completed with first two shots, usually for a better score, but second shot is fairly rare)
