We investigated singing patterns of Pied Bush Chats across years and nesting cycles. We recorded the seasonal singing activity of 25 males in their natural habitats in Haridwar, Himalayan foothills, India for three consecutive years. The vocal patterns, especially song repertoire size of males, remained largely constant, and this restricted annual variation suggests that the Pied Bush Chats are closed-end learners. Analysis of song bouts during different stages of the nesting cycle and across years indicates that the Pied Bush Chat is an immediate variety singer. The song output in terms of song complexity, song rate, song bout length, and percentage performance time was highest at the beginning of egg laying and during incubation compared to pre-nesting, nest building, and provisioning stages. Such singing peaks with respect to different stages of the nesting cycle indicated mate guarding by male Pied Bush Chats and announcement of fertility status of the guarded female.
