The head is a lid, so it turns around. Begun as a vase form on the potters wheel then altered and sculpted. One of the more simpler birds that I have made over the years.
Humidors were fashionable during the Victorian era when tobacco was an expensive commodity. The lids were formed with space to put a damp sponge to keep the container humid. The Martin Brothers, in England, made salt-glazed humidors in the shape of birds, dogs and monkeys. I have done a series of birds, some as jars like this and some as sculptures.
