We've reworked our feeder setup again, taking down the now out-of-season hummingbird feeder, and hanging two new tube feeders, one for more sunflower seeds, the other for suet kibbles.
When we moved to this house 22 years ago we hung four tube feeders from a feeder tree made of plumbing pipe. It worked, and it was squirrel-proof.
It was at the far end of the backyard, though, out in our wilderness (trees, bushes, swamp and pond edges). To see the birds well, binoculars were required.
Seed was kept in small garbage cans in our walkout basement. Going to the basement, loading a pail with seed, tromping through snow in season, well, it became a bit of a chore. I am not getting younger.
The walkout feature gives us a deck on what is, in the rear of the house, the second level, our living level.
The feeders now hang from shepherd poles fastened to the deck rail. Seed is kept out there in an old chest cooler. Squirrels are trying to gnaw their way in. I think they smell the seed, so I am smearing lid edges with peppermint oil to mask the scent. We will see.
Suet is offered in holes drilled in two 6-foot-long heavy branches stacked against the rail.
There are three pairs of patio doors leading onto the deck, glass stretching 6 by 24 feet if you include the framing. All that glass could be a huge problem for the birds. We've tried several ways to mark the windows, to warn birds away.
