These clocks announce each hour with actual bird or fishing sounds. A built-in-light sensor deactivates the sound when the room is dark for uninterrupted sleep. Plus, they come complete with descriptive literature that provides information on the areas of the country where the birds and fish are prominent and each species’ feeding habits. Diameter: 13-1/2".
