The bird stick efficiently protects the top of your Christmas tree against damage and breakages caused by birds landing. The birds will sit on the stick instead of the leader or indeed further down on the tree where the branches are thicker and stronger.
Attach the stick to the leader from the year before just under the top whorl. Then your tree can grow freely and undisturbed.
The peg is made from UV stabilised plastic and is therefore durable and long-lasting.
