Saw this nifty bird feeder on our walk home from BART just the other day. Looks like it was made out of a plastic bottle, some twine, and a few other unidentifiable plastic parts.
When I was younger, we liked to feed birds in our backyard out of old Marie Calendar's pie tins.
That "unidentifiable plastic part" is actually a super smart product. It is designed to screw on to the bottle in lieu of the cap. It instantly transforms a 2 litre pop bottle into a feeder!
There are a couple of versions available. This one from Amazon:

and a window mounting version from Lee Valley Tools:

my only concern is plastic is toxic especially when sun hits it and then more off gasing.
