These photos have been floating around the Internet and came to me through a friend. Can you just imagine how delicate and soft these birds must feel against the skin?
Go here Humming Story to read how these pictures were taken.
Several years ago the "Birds and Blooms" magazine featured a gentleman who created a life-size cardboard copy of himself and placed it in a lawn chair. The cardboard man had bird seed placed in its hand. After the birds got used to eating from the cardboard hand the man replaced it with himself and it wasn't long before the birds accepted the seed from his real hand.
People wrote in to the magazine asking where they, too, could get a cardboard cutout so they could hand feed the birds. The gentleman soon had all the business he could keep up with making replicas for people.
Chickadees are relatively easy to encourage to hand feed. I've never done it but it's on my "to do" list for "some day"
