Studying the work of birders gone by

The North American Bird Phenology Program, is asking for volunteers to enter data from 6 million note cards, dating back to the 1880s. The note-cards, now housed in 40 filing cabinets in Patuxent Wildlife Research Center, document sightings of migratory birds. The program is looking for volunteers to enter the data into a searchable database. If you are interested in helping, go here.
