Ravens in Winter is a 1989 book by Bernd Heinrich.

It is a study of the behaviour of ravens in the forests of Maine.

A review of Ravens in Winter by Publishers Weekly wrote "The story related here, which is constructed from his [Heinrich's] field notes, moves slowly; we learn a good deal about scientific methods and a lot about patience.

"[1] A New Scientist review summarised the book concluding "It also contains Heinrich's own—and excellent—drawings of the various raven postures, a comprehensive review of the literature, beginning with the Bible, and even a section of the ravens of the Tower of London.

"[2] It was an Evergreen Audubon & Nature Center Book of the Month.
