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.

Do loons call while flying?
Birds Tell Us to Act on Climate Common Loons have another, more cheerful “tremolo” call. This undulating tone, tagged the “laughing call,” is given while flying.

Are loons crazy?
This ornithological display makes me wonder if the word “loon” means a bird is related to “loony” or “lunatic,” meaning crazy.
