Ask each child to bring in an empty orange juice or milk jug container. Cut two medium-sized holes on each side of the container. Punch two holes in the top of the container and use wire or string to make a hanger on top. Have children paint or use decoupage material to decorate their bird feeder. Make two slits underneath both holes just large enough to slide popsicle sticks through. Before doing so, add a little hot glue to the slits to hold the stick for the birds to perch on. Fill with birdseed and hang these feeders near a window where the children can see them from indoors.
