Do you think birds are interested in time? They sure do show up at our feeders at regular times. I don't think they need a clock, though. But if you could use one this birdhouse makes a great one! It stands approximately 11¾" high, 11½" wide and 3" deep. It has a 3" quartz clock that is inset and can be removed for battery replacement when needed. It is a great addition to your home decor!
