I always think of how privileged we are to have families of loons on Caribou Lake. I love to watch them and listen to their melodic calls. I thought folks might be interested to know about the four basic adult loon calls: wail, tremolo, yodel and hoot.
The wail resembles a wolf howl. Individuals use this call to locate their mates and chicks.
The tremolo sounds like a quavering laugh. It is typically used when loons are disturbed. It is the only call loons give while flying.
The yodel is a sustained call made up of several repetitions of a three-syllable squeal. It is an aggressive call usually given in territorial confrontations by male loons. Each male has an individual identifiable yodel. Only male loons yodel.
The hoot is a soft, one-note call loons use in close quarters. Most people never hear this call.
Chicks give a high-pitched call that sounds like “a wheet-wheet-wheet.” It is generally reserved for begging for food from their parents.
