By attaching these hooks to the Garden Pole it increases the number of feeders you are able to hang in one place. The more varieties of food you are able to offer the higher the number of bird species you will attract. We recommend using at least 2 hooks on one garden pole as it will prevent the pole becoming unbalanced. However more than 2 hooks can be hung at any one time. To hang the hooks, simply slide the hook over the pole to the desired height. Please note the garden pole is not included. Also available in Green.
