Personal bird checklists for each month, season, year, and day. The checklists show all the species pesonally seen in each time period as well as the species seen by others. These personal checklists are a result of information entered into the electronic seasonal report software. The month record checklists, compiled by Bob Janssen, were derived from M.O.U. files, personal observations, and other sources.
