Pearse", "hasEmail": "mailto:apearse@usgs.gov"}, "description": "The mallard (Anas platyrhynchos) is an abundant and wide-spread duck species that exhibits considerable variation in migratory behavior due to a relatively large body size and behavioral plasticity in habitat use. Understanding migration and other movements of mallards has societal interest in a wildlife management context because mallards are a preferred species of waterfowl by hunters and have the largest annual harvest of all duck species in the United States. We monitored juvenile mallards during autumn-winters 2018-2019 and 2019-2020 to determine factors associated with timing, distance, and direction of regional and migration movements during autumn-winter across the midcontinent of North America.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9GSUQUU", "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.6495a284d34ef77fcb01dcc2.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_6495a284d34ef77fcb01dcc2", "keyword": ["Alabama", "Arkansas", "Illinois", "Indiana", "Iowa", "Kansas", "Kentucky", "Louisiana", "Migratory birds", "Minnesota", "Mississippi", "Missouri", "Nebraska", "North Dakota", "Ohio", "Oklahoma", "Saskatchewan", "South Dakota", "Tennessee", "Texas", "USGS:6495a284d34ef77fcb01dcc2", "biota", "birds", "environment", "migration (organisms)", "plant and animal tagging"], "modified": "2023-09-11T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-103.4, 29.8, -81.9, 49.2", "theme": ["geospatial"], "title": "Mallard migration and regional movement timing, distance, and direction data, 2018\u20132020"}
