New Strategy is Indicated

This is a time of year when suet is in high demand.  It is also a time of year when we're most likely to see Common Grackles at the feeders.  And grackles love suet.  This is a bad formula.  And it means suet is disappearing.  Not just to voracious woodpeckers and catbirds, but also to the grackles.  I believe I need to improve my odds.  I am thinking of replacing one of the cakes with an upside down suet feeder which should resist all but the gymnastic birds.  The woodpeckers can get in, but the grackles will have a tough time.  Will this work?  It was a dubious experiment last year.  But I need to try again.
