My requirements were easy, cheap, and it can't look like a soda bottle.

Step 1: Parts

Parts List:
clear plastic bottle,
chopsticks,
plastic container slightly larger then bottle,
wire, or string, etc.,
utility knife,
marker,

Warning! Knives are sharp, cutting plastic can be tricky!  You may need a few plastic bottles to practice on.

Step 2: Mark Top

Fill or drain the liquid (water) until it reaches the narrowing of the bottle top.  Mark level with marker.

Step 3: Remove Label

Peel off the label, I used Goo Gone to remove the glue from the bottle after removing the label.

Step 4: Score the Top

Score where you marked the top.  Scoring the plastic helps when it comes time to cut.

Step 5: Cut the Top Off

Cut along your scoring, save the top, we'll use it in the next step.

Step 6: Mark Holes

How you cut your holes can depend on the bird and the feed.  Finch's apparently like to eat upside-down, slots are cut so they can get to the feed.

I'm not feeding finches, so I cut holes.  Use the curve of the top we cut off to mark the holes for the birds to feed from.  Center the top along the side of the bottle, start marking at the center top to the left then the right.  As you mark along the edge you want to rotate the top, so it is flush with the side of the bottle where you are marking.  Keep marking until the "curve" has "straightened out" running straight up and down the bottle.  You don't want to force the top down around the curve of the bottle causing it to bend.  Next to cutting this is the trickiest part.  Mark a horizontal line from the bottom of the left and right legs of our curve.  Now repeat on the other side of the bottle.  Add more paired holes as you have room for, you'll probably want to stagger them 90 degrees as you go up the bottle to give the birds more room to feed.  The intro picture illustrates the placement of the holes.
