We have a suet cage with a roof so only woodpeckers, nuthatches and other birds that are comfortable upside down are able to feed from it - keeps the starlings away. A very clever Gray Catbird has learned how to jump from the deck railing and hover for a second, long enough to reach up and grab a bit from the underside of the cage. Perhaps it learned to hover by watching the hummingbirds (just kidding)? Michelle Gregoire Westbrook
