Territorial Call of the American Bittern | Bird Academy • The Cornell Lab

Bittern | The Wildlife Trusts

Here a female bittern makes a loud rattling call that attracts a male bird and this is one of the recordings I am aware of showing bittern courtship behaviour. Using this vocalisation to locate breeding females using Automatic Acoustic Devices and visual spectrogram analysis is a useful research tool c.
