"Common Loon," Wikipedia, the free encyclopedia. Loons produce a variety of vocalizations, the most common of which are categorized into four main types: the tremolo, the yodel, the wail, and the hoot. Each of these calls communicates a distinct message. The frequency at which loons vocalize has been shown to vary based on time of day, weather, and season. They are most vocally active between mid-May and mid-June. The wail, yodel, and tremolo calls are sounded more frequently at night than during the day, and calls have also been shown to occur more frequently in cold temperatures and when there is little to no rain.
