Page "Northern Mockingbird" Paragraph 29

In addition to its well-known song, the Northern Mockingbird uses a variety of calls to communicate specific information.

As with its song, these calls are among some of the louder sounds produced by birds of its size.

Mockingbirds make a harsh, raspy noise when chasing other birds out of their territory.

A similar but distinct call is used when defending against predators like a hawk or falcon.

Other calls include a wheezing noise, a " chuck " note, and a very piercing series of notes " high low " repeated twice.
