I made this bird feeder earlier today. I have three more bottles so the boys can make their own and either hang in the yard or gift to someone.
2 liter bottle
string or yarn
Cut two good sized holes in the bottle (I made rectangles and then rounded the tops just for fun). Poke two holes for the stick right below the big holes. Add the string to the neck and tie to a tree limb. Add bird seed. Sit back and watch!
We put ours up this morning and already had one new visitor. Gabriel, in his excitement, scared off the poor bird though!
If the squirrels start getting into it, I'll poke a hole in the middle of a plastic plate (from the dollar store) and string onto the top of the bottle.
