This 1970s silver plastic filigree Christmas ornament by Renown makes a chirping bird sound when plugged in. I used to put up several small trees throughout my home, and one of my favorites was filled with clip-on bird ornaments on the branches and my chirper ornament hidden inside near the trunk. I don't think anyone who saw that tree failed to comment on how wonderful it looked and sounded.
The ornament is about 3 inches diameter and in excellent working condition with no damage. The plug prongs are the old fashioned non-polarized type. The box has minor storage wear but is intact.
