I took the big PLUNGE and lost my mind and went out and purchased Wild Birds Unlimited APS customizable Bird Feeding System, otherwise known as APS. I got tired of changing bird feeders and having the squirrels rob me blind. In total I bought 3 different systems for three locations around the house. You may ask, 'Are these systems affordable'. The answer to this is, ' UM HELL NO', lol!!! Be prepared to fork over an arm, a leg and a lung when you decide to purchase these. I can't even imagine what got into me, but what's done is done. I think I spent close to $1000.00 on all this crap, lol. I should seriously get by head checked at this point. The system is very addictive and the pieces add up quickly. I hope these is the LAST bird feeding system I ever have to purchase. I have literally thrown away a ton of money trying new feeders and wasted bird feed going to the squirrels, so hopefully this solves the problems. If not...please point me to the closest bridge so I can JUMP :)
(UPDATE - 2015 - It's been just over a year since I purchased this system and I have to say it was the smartest thing I ever did. It was worth every penny and than some. Everything is still going strong, and I no longer feed squirrels expensive bird food mixes, I feed birds! I love how you can change the unit depending on your mood for the season. I will continue to purchase pieces to expand. I can not say enough about these units - they are GOLD).
STATION ONE: FRONT OF HOUSE
I also have a Hawk Guard and a Cylinder Feeder for up top when I take the House Feeder Down. In additional I have also added a feeding tray under the House Feeder for smaller birds. This feeder plain rocks. Not ONE Squirrel has been able to make it's way up to this thing. They tried at first, but NO GO and finally gave up the battle. The baffle has done the trick. I can safely place expensive bird foods all over this thing and know that only the birds are eating from it. I also have seen a BIG decrease in House Sparrows and Grackles as well.
STATION 2: SIDE OF HOUSE:
Another beast of a unit. I have added a Feeding Tray to this for Cardinals,and it too is anti squirrel. LOVE IT. Nothing has been able to climb that baffle system. My expensive blends of nuts and fruits are protected. My birds have never been happier.
STATION 3: BACK DECK AREA
Now this one is NOT squirrel proof, but I combat it by only using Pepper suit cakes here and it works wonders. I also make my own suet cakes for here and just add tabasco sauce or pepper flakes. In a years time I have never seen a squirrel near this unit. My Norther Flickers LOVE this feeder. I have added a double suet feeder to this in hopes of attracting the elusive Pileated Woodpecker. We will see...
