WOS thanks Sylvia Halkin and Walter Berry for producing a major update to the chapter in the Manual of Field and Laboratory Exercises for Ornithology regarding bird vocalizations. This chapter outlines exercises that provide hands-on experience with the recording and analysis techniques that are used to explore the diversity and functions of sounds made by birds.

As with all chapters in the Manual, the contribution by Halkin and Berry is available free of charge for instructors and students of ornithology. WOS hopes that this resource will be of value for its members—and future members—and to ornithology at large.
