Goals
The first Ontario Breeding Bird Atlas was carried out from 1981-1985, and involved the efforts of over 1,300 volunteers who collectively carried out more than 120,000 hours of field work. This resulted in a data base of over 400,000 bird-locality records, giving unprecedented information on the breeding distribution of birds in Ontario.
