• Geographic area covered : North America (US and Canada) Approximately 16,000 participants from all states and provinces.
• Type(s) of habitat : Backyards, nature centers. 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
