Behaviour:
The characteristic shrill song of the male can be heard through the day and into the night. It usually consists of three syllables ('tsitsitso'), which at higher temperstures merge completely into a sharp 'tsrit', audible from about 10m. As a reaction to disturbance by another male, more of these syllables are added together to form a louder sequence. The song can often be heard along forest tracks even in misty, overcast weasther and even after the first night frost, but it is not usually easy to find the songsters. [1]
