Breeding Bird Atlas participants

The thousands of people who contributed so much time and effort to their local atlas projects, either in field work or coordination, made this possible. These participants spent tens of thousands of hours scouring their local haunts, familiar and unfamiliar, in search of nesting evidence. They produced the raw material on which the BBA Explorer was built. People who helped us obtain data from individual projects are listed on each atlas 'home' page in BBA Explorer.


Feedback and review

The participants of the Maryland and DC breeding bird atlas, and that project's board at the Maryland Ornithological Society, were the guinea pigs as we developed BBA Manager & BBA Explorer, diligently reporting errors while keeping up with data entry for their project; Walter Ellison, Bob Solem, Elliot Kirschbaum, Fred Fallon, Jane Fallon, Sue Ricciardi, Charles Vaughn, and Chan Robbins, and a host of others from Maryland provided extensive (and most welcome) feedback. A year later Vermont BBA joined in, and Rosalind Renfrew, Kent McFarland, Ted Murin, Dave Hoag and others were among the more patient reporters of glitches and requests for their improvements. Janet Evander provided early usability critiques. Many others contributed as well, and we welcome additions to this list for people we overlooked.


Ongoing redesign & improvements to BBA Explorer and BBA Manager (since 2004)

In 2004 we redesigned BBA Manager to accommodate a growing number of atlases, and expand the public search tools into what is now BBA Explorer. In addition to input mentioned above, a volunteer team from the MD & DC, New Mexico, and Vermont atlases patiently reviewed potential new screens and generated feedback and ideas: Ted Murin, John Sutton, Rosalind Renfrew, Walter Ellison, Steve Antell, Steve Fettig, Nancy Martin, George Jett, and Sylvia Harris. Also, more recently, Joan Walsh from Mass Atlas II and Anthony Gonzon of Delaware Atlas II have contributed ideas for new reports and improved presentation. We love feedback, keep it coming.

Inspiration and support

NORAC members (North American Ornithological Atlas Committee) welcomed and encouraged this project. Steve Kelling and his team at the Cornell Lab of Ornithology set the bar high with regard to what birders can do with the web. Denis LePage also encouraged us in early development, and sent us his data model for the Ontario BBA project which was very helpful. Denis' web page (linked from BBA Explorer home) is very comprehensive and helped us track down atlas information. At Patuxent: Marshall Howe and Keith Pardieck provided helpful feedback and ideas, and Jang Byun provided general database wisdom. Our information technology staff at Patuxent, especially Lisa Whitman and Lois Loges, keep the servers and sites running and the databases backed up.


Our development team

Susan Goplen and her team at the USGS Rocky Mountain Mapping Center built our BBA mapping tool (using ArcIMS) that we have since modified and added projects to. Erika Hanner and Kristen Danielson helped with importing several atlases, and even re-entered two state atlas project datasets by hand that we could only obtain on paper. Naoko Griffin, Anna Ott, Jessica Hopkins, and Allison Sussman imported many atlas datasets, created and maintained GIS data, and contributed much to the content and functionality of most of the pages through extensive testing and brainstorming. Bruce Peterjohn was the originator of and driving force for this electronic atlas, as well as the go-to for problem-solving, atlas knowledge, and general project direction. The database development, software architecture, and web page coding and design (and any bugs) were completed by Mark Wimer.
