Number of calling males is unknown. Each sample consists of the first 50 calls in which the whistle was clearly visible on the spectrogram and was not obviously overlapped by other vocalizations. The value for Monument Lek represents a count of 50 calls from a single channel recording taken from the multi-channel array. Since recording conditions varied across sites, these rates of double whistle (DW) detection are not accurate estimates of the rate of its occurrence
