I was cleaning up some things in the cupboard and found an old open bag of marshmallows. I started to throw them out but decided instead to see if the birds that come to eat would like them. The first group i put out were ignored for a couple of days and then they disappeared. I only put a few out at a time and now they last about a day. The sequence shows one of the sparrows coming up, taking a peck and then checking around before taking another. I think some of the birds have developed a sweet tooth!
