IF You like waking up to Birdsong, but that have not cages, in your house you really like, I propose an idea for every day the birds are to you.
If you have a garden or a balcony, you can make this very easy bird feeder, just with a plastic bottle, wooden spoons, a hook, rope and food for birds.
Starts piercing the bottle cap and Come on in a metal hook screw and hold it on the other side with a nut for its size, such as are used for hanging pictures.
Then the cylinder bore to pass the handle of the spoon from side to side and only part of the spoon has to be the largest pierces a little to pass the food of birds and stay there.
You can place the number of spoons you like, and then fill it with food for birds
