Fortress Triple Tube Feeder
The Fortress Triple Tube squirrel-proof bird feeder looks mighty impressive to the eye. It is another variation of the tube feeder inside a metal cage. The difference between this and other feeders is that there are three tubes which make up the feeder. You can fill one it with three different kinds of seeds to attract different types of birds.
It is very similar to the Opus Top Flight feeder. However, they have made one improvement over the Top Flight feeder: the lid locks in place. This prevents the squirrel from removing the lid to get to the seed. (And speaking from experience, this is exactly what happens with bird feeder that don’t have locking lids).
All-in-all, it is a pretty good squirrel-proof bird feeder.
Firstly, all tube feeders tend to have a problem with inclement weather. The seeds at the bottom of the tube tend to get wet from the moisture that gets in at the seed port. This causes the bottom layer of seeds to clump, preventing the dry seeds above them to fall down.
Secondly, this feeder has a seed dish under the tube to catch fallen seeds, the same as the Opus Top Flight. All the squirrel has to do is hang upsidedown on the cage and eat seeds out of the dish (which, believe me, he’ll do).
So, this type of feeder tends to not be 100% squirrel-proof. Still, the metal cage is chew-proof, and it does fairly well.

If you are specifically looking for a triple-tube feeder, you might also want to consider the Opus Copper triple-tube bird feeder. It has the extra feature of a built-in squirrel baffle, so it is impossible for the squirrel to hang upside down to eat from the tray.
