Vintage Singing Bird Dial Wall Clock in Dark Green 13"

Round wall clock with illustrated bird dial. Dark green outer frame with cream face. Three black hands. Decorative bird species markers around the face.  Plays bird calls!  You will have to reset it for your time zone.  13 round This is a Mark Feldstein Original Singing Bird Clock, specifically a 13-inch model featuring a green matte frame.  It plays the authentic recordings of 12 North American songbirds, with a unique call chiming at the top of each hour.  The clock includes a light sensor that automatically deactivates the bird sounds when the room is dark.  It requires three AA batteries to operate the quartz movement and audio system  I cannot make the birds sing with the hour, but the reset button makes bird noises, so the sound works.  I just haven't heard the bird call when the time changes.  Might be defective or user error. ???
