Enjoy a myriad of feeding garden birds just outside your window. The window bird feeder is made of glass and is mounted directly on the windowpane. The mouth of the bird feeder is designed so that garden birds can easily settle on the glass lip and feed. At the same time, the clear glass makes it possible to study the different species of birds close up.The bird feeder is held in place with double-sided tape on the outside of the pane, where it sits discreetly and elegantly. To refill, just pour the seeds through the opening into the feeder, which can hold up to 350 ml.The glass can be easily removed for cleaning. Moreover, the glass is frost-proof, so it can be used all year.
