Birding is one of the most popular and rapidly growing recreational activities in the United States. Vast quantities of data are recorded by birders and stored in a variety of open digital sources including: submissions to rare bird records committees, breeding bird atlases, birding list-servs and newsletters, and recently through online checklist programs such as eBird. Using these sources I am interested in documenting range expansion and changes in migratory bird phenology using this data. In addition, I am interested in determining how accurately the birding community can detect species declines. Currently I am focusing on analysis of a decade long presence/abscence data set of an avian community documented by a mail carrier, C. Leon Hicks (my father), in south-central Kansas. He has recorded the presence and absence of bird species daily along his mail route for over a decade with over 2/3rds of days surveyed making it one of the most intensely monitored avian communities in the United States.
