Development of a Birdie Sanctuary

The birdfeeder itself is one of those clever gadgets made to screw on the top of an empty plastic 3-liter soda water bottle. I got it at a country style general store named Callaghan's for $12. Cast steel construction, I think. Heavy. Solid. It doesn't go brittle in the sun like plastic does with time.

Also at Callaghan's, I bought an iron rod which was curved into hooks on both ends. It allowed the feeder to hang nearer toward eye and hand level while still being high enough out of the reach of smaller, less-feathered critters.

The rod, too, as made to last a long time. The hooks, however, where too small for the tree limb that I wanted to suspend the birdfeeder from. So I used unbent coat-hanger wire to form a loop which went about the limb. The rod hooks on to that, and the birdfeeder hooks on to the other end of the rod.

Bird seed goes in the 3-liter bottle as it stands upright. The feeder-perch assembly caps it off when full. The 3-liter bottle is now flipped to bottom up position. Seeds come out through the holes in the feeder-perch assembly. The birds land on the four wire perches and eat the grains as more dispenses from the store above.
 
Ah, but what does the birdfeeder hang from if it is upside down? The answer to this: there is another wire hoop which hooks on to holes in opposite sides near the bottom of the 3-liter plastic bottle. And that is where the iron rod hooks on in the first photo above.

Now, a word about the stripes. As you can see in this moving GIF illustration, those result from alternate layers of regular mix wild bird seed and straight Sunflower seed. One 25-lb. bag of the former and one 5-lb. bag of the latter yields 6.33 fillings of the feeder.

The funnel is fashioned from a 20-oz. (592 mL) plastic soda water bottle cut in to just after the neck slopes into the body. Inverted, the mouth and neck fit perfectly into the 3-liter bottle mouth as a fine funnel.
 
The scoops for the bird seed and Sunflower seed are also made from 20-oz. plastic empties. I have no idea how much each measures out, but the amounts are consistent enough to keep the stripes constant, and that's the important part.

See, my idea is that if I present the same pattern to the birds each time the birdfeeder is full, then they may remember it as a sign that "dinner is served."

Thus, a birdie "Howard Johnsons" for weary feathered travellers is opened, but destined for further additional development.
