Our strategy for Timber Tumble Level #14 is to wait for the swinging boulder to approach the leftmost structure. The remote is in the extreme right structure; detonate by either sending the Yellow bird above everything or bouncing him off the tire below (Sal went high; Slim went low). Use the Black bird to destroy whatever remains. The score in the video below is 215,330.
Below is Slim’s video, where the Yellow bird goes low. A one-bird clear is possible from this strategy, though the two-bird solution still yields a score of 224,400.
