Squirrels not only eat seed from bird feeders, but squirrels also scare birds away. So even if you have a weight-activated “squirrel-proof feeder”, you might still want to baffle it to keep squirrels from jumping on it and frightening birds away.
Erva Starling-Proof Suet Feeder Review: Want to keep your suet feeder from being dominated by European Starlings and Common Grackles? One way is to put the suet beyond their reach in Erva’s Starling-Proof Suet Feeder. While I’m a fan of upside-down suet feeders and have used them for years, Erva’s method of putting the suet deep in a cage has promise. This feeder allows smaller birds access to the suet while caging larger birds out.
