Nice design Eric 👍 You might include a small mallet on that squirrel work bench so they can crack open some pecans or walnuts. Better yet, fill with those Brazilian nuts, that no one seems to like!
Feeding the local wildlife is considered an obligation IMO, but teaching the spawn to open doors is pushing things 😀
I like the feeders that have the acrobatic apparatus that must be navigated to get to the "prize". More entertainment!
