There is a metal plate that sits in place on the lower back that can detach to open. I believe this is to put something like a candle on the inside of the bird to light up so I believe this is a lantern as well.All in all this is an awesome collectible cast iron piece and would go excellent in any home. Dimensions: 3' or 36" H x approximately 12" x 8 1/2 at the base. If you have any questions, please feel free to send me a message and I'll be happy to help.
