Data are presented for 408 species of birds.  Seasonal phenology effects are presented for selected latitudes and years, documenting changes in visibility and a variety of statistics to allow users to assess the significance of those effects.  Results are presented as csv files, with additional information provided  in R data sets, and summarized graphical form in species-specific pdf files.   Metadata associated with this data product provides information specific to the analysis results.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9812ULJ", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}, {"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.633ebe9ed34e342aee05f675.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_633ebe9ed34e342aee05f675", "keyword": ["Bird Breeding Phenology", "Bird Trend Estimates", "Breeding Bird Survey", "Breeding Bird Survey Analysis", "Canada", "Climate Change", "USGS:633ebe9ed34e342aee05f675", "United States of America"], "modified": "2022-09-20T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-169.8047, 22.5937, -48.1641, 71.9654", "theme": ["geospatial"], "title": "Phenology effects in the North American Breeding Bird Survey"}
