The Regal Style Cage Suet Ball Feeder holds up to four suet balls at a time. The outer cage prevents access to squirrels and larger birds, while small songbirds like juncos and chickadees can come and go as they please. The copper coloured polished roof lifts easily for filling, and lends the feeder an elegant look that works in nearly any setting. The metal construction is so sturdy that it comes with a lifetime warranty from the manufacturer. Suet balls provide a healthy source of insulating fat and carbohydrates to wintering birds in particular, but they will feed from it year round if it’s kept full.
