LeAnn White", "hasEmail": "mailto:clwhite@usgs.gov"}, "description": "During 2010 to 2013, waterbird mortality surveillance programs used a shared protocol for shoreline walking surveys performed June to November at three areas in northern Lake Michigan. In 2010 and 2012, 1244 total carcasses (0.8 dead bird/km walked) and 2399 total carcasses (1.2 dead birds/km walked), respectively, were detected. Fewer carcasses were detected in 2011 (353 total carcasses, 0.2 dead bird/km walked) and 2013 (451 total carcasses, 0.3 dead bird/km walked). During 3 years, peak detection of carcasses occurred in October and involved primarily migratory diving and fish-eating birds, including long-tailed ducks (Clangula hyemalis; 2010), common loons (Gavia immer; 2012), and red-breasted mergansers (Mergus serrator; 2013). In 2011, peak detection of carcasses occurred in August and consisted primarily of summer residents such as gulls (Larus spp.) and double-crested cormorants (Phalacrocorax auritus). A subset of fresh carcasses was collected throughout each year of the study and tested for botulinum neurotoxin type E (Botulinum neurotoxin type E  ). Sixty-one percent of carcasses (57/94) and 10 of 11 species collected throughout the sampling season tested positive for Botulinum neurotoxin type E  , suggesting avian botulism type E was a major cause of death for both resident and migratory birds in Lake Michigan. The variety of avian species affected by botulism type E throughout the summer and fall during all 4 years of coordinated surveillance also suggests multiple routes for bird exposure to Botulinum neurotoxin type E   in Lake Michigan.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/F7GX48NM", "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.5633bfb9e4b048076347f028.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_5633bfb9e4b048076347f028", "keyword": ["Clostridium botulinum", "USGS:5633bfb9e4b048076347f028", "avian botulism", "disease", "surveillance", "volunteer", "wildlife health"], "modified": "2020-10-16T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-88.247680664051, 44.110939829689, -84.677124023569, 46.217549030468", "theme": ["geospatial"], "title": "Avian botulism type E in waterbirds of Lake Michigan, 2010-2013"}
