媒体文件注释
On a canal beside a dike. May be the same bird as ML 2812. BNA: All of these vocalizations appear to represent the Recognition Call of BNA. As in ML 2812, it appears that there are two birds calling here (this is especially evident at 0:27-0:34), possibly both a male and female. (CAM - 4 March 2005). Habitat: Wetland, Freshwater.
