DVOC thanks Princeton University Press, FOHR, Debbie Beer, Tom Stephenson, Scott Whittle and Jessica Pellien for their contributions in organizing and leading this special event.

Tom Stephenson has been birding since he was a kid under the tutelage of Dr. Arthur Allen of Cornell University. His articles and photographs are in museums and many publications including Birding, Birdwatcher’s Digest, Handbook of the Birds, Handbook of the Mammals of the World, andGuide to the Birds of SE Brazil. He has lectured and guided many groups across the US as well as in Asia, where he trained guides for the government of Bhutan. He has donated many recordings of Eastern Himalayan rarities and other Asian species to Cornell’s Macaulay Library of Natural sounds. He was on Zeiss’s digiscoping team for the World Series of Birding and in 2011 his own team won the World Series Cape Island Cup.
As a musician he played concerts and did studio work for many years, working with several Grammy and Academy Award winners. His clients included the Grateful Dead, Phil Collins and the FBI. He joined Roland Corporation in 1991, managed the recorder division, and retired recently as Director of Technology. His latest book, The Warbler Guide, is published by Princeton University Press.

Scott Whittle has 20 years of experience as a professional photographer and educator. He has an MFA in Photography from the School of Visual Arts, is a fellow of the MacDowell Colony, has held the New York State Big Year record, and has birded throughout the United States. He lives in Cape May, NJ where he leads workshops and pursues his passion for birds and photography.


This special Warbler Workshop is jointly sponsored by the Friends of Heinz Refuge (FOHR) and DVOC.

Identifying the warblers and other species singing in the field is one of the most enjoyable and satisfying aspects of birding. However learning and remembering the important ID points of difficult and similar vocalizations can be challenging.

Sonograms are an important tool that can be used to understand what makes a vocalization unique and how to differentiate similar-sounding species. This lecture or workshop explains what sonograms are and shows how they can be very helpful in identifying potentially confusing bird vocalizations.

The talk also explains how understanding a song’s structure, and the characteristics of the Elements and Phrases that make up the song, can speed up the identification process and make it easier to remember all kinds of vocalizations. There will also be a discussion of how to use a song finder to quickly identify a singing warbler using the objective, easy-to-hear qualities of a song.

The authors will also explain a simple 3-step memorization system that he has used many times to memorize 300 or more songs for a trip to a new country.

In addition, if time permits, there will be a discussion of how to study and identify the vocalizations of groups of similar-sounding species, such as western thrashers, and also how to learn the very short chip and flight calls of warblers and other species.
