Cardinals, jays, woodpeckers, and chickadees are just some of the bird species who are likely to be attracted to a suet feeder. This one features a double cage construction designed to discourage unwanted diners like squirrels and cats. Suitable for year-round feeding, it's made of spot-welded, nylon-coated steel. The trap is easy to open and clean, and the locking mechanism on the lid doubles as a handle to prevent predators from opening the feeder. Developed with the British Trust for Ornithology.
