Here is a gorgeous bird feeder that lets you keep a closer eye on your feathered friends. The Krick View Window Tray Bird Feeder has a semicircular top and base to fit inside your home. Its polycarbonate window lets you see the birds.
You can mount this into most single and double-hung windows from 27″ to 36″ wide. This bird feeder doesn’t have a 2-way or mirrored panel to prevent birds from attacking their own reflection.
