Easy to use, and simple to refill and clean. This 12.5cm (5") wide wire cage fits all standard suet cakes. It’s equipped with a chain and hanger hook, and a simple double lock mechanism to deter squirrels from making off with the cake. Suet provides vital fat and carbohydrates to many bird species, particularly in winter, when insects are scarce. We have several Pinebush Suet Cake Feeders located on our farm and we find that the ground feeding birds tend to clean up any crumbs that get chipped off the suet blocks. Our feeders are visited by black-capped and chestnut-backed chickadees, juncos, flickers, and downy and hairy woodpeckers.
