8-10 3 Birds
Aim first yellow bird at first thin plank on pyramid.
Aim second yellow bird in roughly the same spot. Detonate lower TNT box and hope side of pyramid shears off and blows up middle TNT box. This box should detonate before tilting completely over. This will ensure the stone plank next to it is displaced, leaving access for the third bird to hit the far TNT box.
Aim third yellow bird at far TNT box, popping last pig and clearing out any remaining debris. Makes sure to strike at wood canopy protecting last pig.
