The calls of twelve different New Zealand native birds is heard, one each hour, on the hour. The auto playback is off during the night. The clock has a dark and light wood surround and is of strong, sturdy construction with a black plastic back. There is a two page information sheet on the birds and an instruction sheet for the clock's operation. The clock takes 3 x AA batteries, one for the clock, and two for the bird songs. A reset button allows setting correct bird songs to the hour. A great way to learn to recognise the various calls.
