By attaching this feeder to the outside of any window with the included suction cups， you can enjoy closer and more frequent bird sightings - all from the comfort of your home! With food for them and fun for you， this feeder promises hours of enjoyment as you watch your favorite backyard birds eating and flying about right outside your window. The clear design makes it easy to see the action from any angle. Birds will love the wide opening which provides plenty of space for different sizes of birds and allows them to hop in and out of the feeder easily. Your feathered friends can perch comfortably on the feeder’s ledge or stand directly in the seed tray. The hooded tray will protect your birds and help keep seed dry. For your convenience this feeder is also easy to use. Simply attach the suction cups to a clean window - you may need to moisten the cups for better suction.Find the WINDOW BIRD FEEDER CLEAR at Ace.
