Milk Carton Bird Feeder

What you'll need:

Empty quart sized cardboard milk carton
Scissors
String or cord
Hole punch or pencil
Bird seed

How to make it:
Have an adult help you cut a hole in the bird feeder – it should be big enough so a bird could come and sit and eat the feed, but not too big or the carton will become unstable.
Have an adult help you cut a hole using the hole punch in the top of the milk carton and put a string through the hole. Alternatively, you can poke a hole on either side of the flap at the top of the carton by poking a pencil through the top.
Tie a knot in the string.
Fill the carton with bird seed until it reaches the top of the hole.
Hang the cart on a tree branch and watch the birds enjoy their snack!
Tips:
A quart size carton works perfect as it isn't too large and holds a decent amount of food.
You may choose to decorate the outside of the carton but keep in mind that it will be outside in the elements and decorations may wash off in the rain. Also, you wouldn't want the birds pecking at flaking paint!
Check your bird feeder regularly and refill as needed
