Generally rural or suburban Primary species covered : Landbirds that visit bird feeders Sampling Design : Depends on citizen scientists (data collected by volunteers). Sampling locations are determined by the volunteers. Field methods : Counts at feeders, species, number and weather conditions, effort information Data format : Over 5 million records per year, maintained in Oracle data base at the Cornell Lab of Ornithology. Raw data available - contact the Lab. Data retrieval tools including simple trend graphs and distribution maps available to the public at: http://www.birds.cornell.edu/pfw/DataRetrieval/dataretr_index.html Sample size : Counts submitted from about 10,000 participants each year, over 5 million birds reported in 2003.

Applications for the data : long-term trends in bird distribution and abundance; timing and extent of winter irruptions of winter finches and other species; expansions or contractions in the winter ranges of feeder birds; kinds of foods and environmental factors that attract birds; how disease is spread among birds that visit feeders Users of the information : Research Scientists Data collected between 1976 and 1987 in the Ontario precursor to Project Feeder Watch. 1976 1987 ground condition Complete North America (US and Canada) Approximately 16,000 participants from all states and provinces.
