The Perky-Pet Wilderness Lantern combines the natural color palette of the outdoors while displaying a calming landscape of buck and doe crossing your path. U-shaped perches adjust to allow you to attract different sized birds and the patented Sure-Lock cap system keeps the lid secure to prevent squirrels from stealing the seed. Remember to clean this large bird feeder once every two weeks with a mild soap and water solution.
