Window Bird Feeder House by Nature Anywhere with Sliding Feed Tray THE PERFECT GIFT for bird lovers and cat lovers! See colorful wild birds from up close. No need to go out. Just sit in your kitchen and have fun discovering your garden birds. Fits on to any plain glass window. This is one of the very best items I have purchased on Amazon. It extremely well-made, sturdy, and attractive! Anyone interested in this feeder should have absolutely no hesitations. SLIDING SEED TRAY MAKES IT EASY TO FILL, AND CLEAN. No need to remove the whole feeder for every re-fill. Simply slide the patented tray out, fill, and slide back in. This is a chore kids will fight over, and elderly hands will have no problem. The sliding tray holds up to two cups of bird seed.. Four HEAVY DUTY SUCTION CUPS ensure your birdfeeder is out of squirrels reach and will never fall. Ever. VIRTUALLY 100% SQUIRREL PROOF. Ever seen a squirrel climbing a glass window? They cant! Keep the feeder installed 10 feet away from ledges, gables and branches and Mr. Nuts doesnt stand a chance. This is one squirrel proof bird feeder! The patented air circulation system will also keep the seed dry and safe from dangerous mould.
