Evolution of a bird feeder

As many of you already know from my "flighty visitors" post, we've recently put up a bird feeder.

Here, I hung the feeder on a random nail.

Worried that our birds didn't have enough space to stand, hubby created this contraption to encourage maximum feeding:

 

The "trapeze" feeder

Then, reading somewhere that bird feeders should be about 4 feet off the ground, hubby reworked the contraption to look like this:

The "damsel tied to the railroad tracks" feeder

Are we encouraging more birds to visit our feeder?   Unsure.
Do I smile at hubby's ingenuity?  You betcha.
