Featuring a decorative brushed copper finish, the Radiant feeder is sure to add elegance to your yard. The wide mouth tube is easy to fill, plus the removable base makes it easy to clean. The Radiant feeder is designed to allow you to Choose Your Birds™ by adjusting perch length to fit different sized birds. The perches adjust to give the little birds a chance! Being able to adjust the length of your perch lets you control who visits your feeder. Rule of thumb: A shorter perch discourages large, and often less desirable, birds.
