When our standard single-cake suet feeder mysteriously disappeared from our backyard (the crime remains unsolved), I took a chance on this nice roofed double-cake suet feeder. The results have been good.
It took our birds (house finches, various species of woodpeckers, chickadees, nuthatches, cardinals) a while to figure out how to maneuver their way into the right stance for getting at the suet, probably because the roof and its overhang briefly confused them. But then it was open season. The advantage of stocking the feeder with two suet cakes seems to be in reducing the need to re-stock to roughly half as frequent a job as it was before. That is, having two rather than one suet cake doesn’t seem to attract more birds; it just means that roughly the same number of birds have more supply to work on, so it lasts longer.
The quality and workmanship are very good.
