I took the cage protector off my suet log a few weeks ago once the grackles left the yard and raccoons were no longer a problem. The woodpeckers loved having easy access to the entire log -- especially the bigger Hairy and Red-Bellied woodpeckers.
But look who I caught eyeing the suet log yesterday.......did you notice the top hole was completely empty?
Yupper!! And here's why! That big ol' crow beak can clean out a suet log in a quick hurry compared to a tiny little Downy woodpecker beak!
