Why do they call loons at night?

The tremolo is also known as the “crazy laugh.” This call is usually a response to perceived threats, including intruding loons, humans, or predators such as eagles. Tremolos are frequently given during territorial interactions with other loons, during night chorusing, and as a duet between pair members.
