The Woodlink Seed Tube Bird Feeder easily turns your yard into a songbird haven. This feeder offers a wealth for you and your songbirds. The four ports are surrounded by sturdy metal reinforcing them. Each port also has a squared perch which enables some birds to eat resting next to the port while others face the seed and dine in a straightforward manner.A sturdy metal cap and base complete the feeder with a metal hanger to place the item on a hook or branch. Holes on the base help ventilate the tube for fresh seed and enable any water to escape. A raised ridge on the base acts as a baffle directing seed to the two bottom ports. The green color of the metal blends with your yard for a natural feel and the roof lifts upward for easy refills. Invite songbirds into your garden with this Seed Tube Bird Feeder.Dimensions: 6" Diameter x 21.5" H.
