This bird has two calls sounds: one is an aggressive, flat tup or chip while the other is a soft, high-pitched buzzy zeet.[1][2] The latter in males is often followed by their song.[2] The zeet call is generally used while under dense cover, whereas the chip call is used while exposed on perches to attract attention or during antagonistic encounters.[2] Both calls are used in nest defense.[2] They also have a distinct, hoarse, buzzing zrrr-zrrr-zrrr call sequence used for mating, during territorial disputes, and when mate-guarding.[2]
