2-12 2 Birds
Aim first blue bird at overhead lamp splitting before impact (time of split appears to be important – I had success splitting a bit early). This usually allows top mini-bird to roll over and get yellow bird in far right corner. It also tends to destabilize entire structure.
Aim second yellow bird at nearby birdcages trying to pass through cages and topple middle tower and also perhaps hit birdcages on far side of tower either directly or as a result of TNT blast.
