Welcome and you may want to try this. If you have a wal-mart where you live go to the craft dept and buy a ball of hemp string about $4 to $5 but it lasts a long time there is lots of in on the ball.
Get multi grain cheerios and also buy a package of pony beads in the craft dept. I tie a pony bead on first then I string awhole bunch of cheerios on the string and tie it up for the birds. Not only is it a toy but they can eat it also.
Don't use papertowel or toilet paper rolls they have glue on them that are toxic to birds.

My name is Connie
