媒体文件注释

Three calls total from at least 2 individuals. Loudest at start and end

观察细节

Calling from Big Bluestem Pond until about 8am when we finally moved on (no playback needed). Rare to hear more than one calling together, but once an individual began singing it would call almost exactly once a minute until another bittern would begin singing somewhere else around the pond.
