New Hampshire Audubon (NHA) began computerizing bird sightings in 1986 utilizing volunteers to enter reports into a database. In 2009, NHA changed to eBird as an on-line data entry system for New Hampshire bird sighting data. This improved the reporting framework, but the original NHA database that contains 22 years of birding data from 188,778 records could not be imported into the eBird system without significant preparation. NHA began the work necessary to import this data into eBird in 2011 and continued the process in 2013.
