Angry Birds Mighty Eagle Walkthrough Hidden Harbor Level 5

Went from left to right to destroy most of the structures with all the birds. Used the second Yellow Bird to get the helicopter and have it land on the platform and some debris takes out some of the right side.

Found that if most of the left structure is destroyed the chances of getting the feather a bit better but not much.

Sent the Sardine Can in the water below the sling.

This level is debris dependent. A couple stone pieces remained and maybe one piece of wood.
