With Wingdow® Loft, you can add a second level perch above your Wingdow® Seat--or simply use the perch as a way to hang entertaining toys, swings, etc. overhead while your bird is using the Wingdow® Seat. If hanging the perch underneath the Loft ceiling, select the perch length that gives your size bird the most head room. If installing the perch above the Loft ceiling, select the perch height based on tail length. Choose a standard hardwood dowel for your perch--or upgrade to a Dragonwood, Manzanita, or textured PVC perch.
