Once you have found a suitable branch, simply slide open the wire loop (1) and hook it securely onto the tree (2). Alternatively pass the wire over a strong branch (4) and slide open the loop and gently lower the ball through the loop allowing the wire to pull taut against the branch (5). Always use the protective tubing when suspending the birdball from trees and shrubs to prevent damage to the bark (3).
