How is the characteristic vocalization of the Whimbrel during migration or flight typically described?
Answer
A series of musical, bubbling notes or a distinct, rolling whistle
The Whimbrel's call is often the first indicator of its presence, particularly when flocks are passing overhead during migration periods. The sound is consistently described as being musical, characterized by bubbling notes or a rolling whistle that is somewhat melancholy in tone. A common phonetic rendering of this sound pattern is represented by rhythmic variations such as 'pip-pip-pip-pip-pip-pip-pip-peeeeuuu,' which typically ascends in pitch before trailing off. This distinctive voice is also utilized by males during the breeding season as part of their territorial displays on the tundra.
