UP FOR YOUR CONSIDERATION IS THIS VERY NICE SINGING BIRD CLOCK BY THE NATIONAL AUDUBON SOCIETY THAT PLAYS A DIFFERENT BIRD SONG AT THE TOP OF EACH HOUR. THIS CLOCK DOES HAVE A LIGHT SENSOR THAT WILL KEEP IT SILENT AT NIGHT OR WHILE IN A DARK ROOM. THIS CLOCK HAS BEEN CLEANED AND TESTED AND IT WORKS GREAT. THE CLOCK RUNS ON 3 AA BATTERIES WHICH I WILL INCLUDE. THANKS FOR LOOKING AND PLEASE MESSAGE ME WITH ANY QUESTIONS YOU MAY HAVE. I OFFER FREE SHIPPING WITHIN THE LOWER 48.
