About ACP

I began writing The Language of Animals—a book about the science of animal communication—in 1995. I thought that book-store visitors might want to flip the book open and begin looking and reading, so I wrote each chapter to stand on its own to some degree. This organization also works on a web site, in which readers can navigate to any section and begin reading. The Language of Animals is out of print now, but you can find it in a library or for sale used on the web. Much has changed since the mid 1990s. The News section, contains short descriptions of ongoing research I have encountered. I welcome suggestions and corrections.

As of 11/12/2016, I have replaced all QuickTime audio, video (and associated code) with HTML5-compliant audio, video and code, which should work in all modern browsers.


The Animal Communication Project is and will remain a nonprofit effort. All contributions remain the intellectual property of contributors and are clearly so marked. You must ask permission of the copyright owner to use any of the contents in any way. If you link to the site, I would appreciate being notified: e-mail Stephen Hart.

The Author/Editor

For about 20 years, I specialized in writing and editing science and medicine journalism.

My work appeared in mainstream periodicals, specialty periodicals for scientists and physicians, popular books, textbooks for adults and children, and on the web.


I built The Animal Communication Project on Apple Macintosh computers using Adobe GoLive, Dreamweaver and Photoshop; Apple iPhoto, Aperture and QuickTime Pro, felt tip Sound Studio and other great software. As of 11/12/2016, all QuickTime video has been replaced with standard HTML 5 video, so no plugins are required in HTML 5-compliant browsers.
