Jennifer Ackerman (born 1959) is an American author known for her ornithology books, including the bestselling book The Genius of Birds. In that book, Ackerman posits that, contrary to popular metaphors such as "bird brained," birds are actually quite intelligent and think in complex ways. Called a "peppy survey of the science of bird intelligence" by The Guardian, the book was a New York Times best seller in 2017. She followed up on this idea in her 2020 book The Bird Way combining personal observations and a literature review of the latest in bird research to discuss various aspects of bird life. She was the narrator for the audiobook version of both books.
