We tested that idea by attaching accelerometers to free-ranging pelagic cormorants (Phalacrocorax pelagicus) and simultaneously estimating energy expenditure using doubly-labelled water. Two different formulations of dynamic body acceleration, VeDBA and ODBA, correlated with mass specific energy expenditure (both R2=0.91). VeDBA models combining and separately parameterizing flying, diving, activity on land and surface swimming were consistently considered more parsimonious than time budget models and showed less variability in model fit. Additionally, we observed provisional evidence for the presence of hypometabolic processes (i.e. reduced heart rate and body temperature; shunting of blood away from non-essential organs) that suppressed metabolism in cormorants while diving, which was the most metabolically important activity. We concluded that a combination of VeDBA and physiological processes accurately measured energy expenditure for cormorants.<\/jats:p>","DOI":"10.1242\/jeb.130526","type":"journal-article","created":{"date-parts":[[2016,5,20]],"date-time":"2016-05-20T09:44:24Z","timestamp":1463737464000},"source":"Crossref","is-referenced-by-count":34,"title":["Counting calories in cormorants: dynamic body acceleration predicts daily energy expenditure measured in pelagic cormorants"],"prefix":"10.1242","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2863-908X","authenticated-orcid":false,"given":"Mason R.","family":"Stothart","sequence":"first","affiliation":[{"name":"Department of Integrative Biology, University of Guelph, Guelph, Canada, N1G 2K8"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kyle H.","family":"Elliott","sequence":"additional","affiliation":[{"name":"Department of Natural Resource Sciences, McGill University, St. Anne de Bellevue, Quebec, Canada, H9X 3V9"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas","family":"Wood","sequence":"additional","affiliation":[{"name":"Department of Biology, University of Manitoba, Winnipeg, Manitoba, Canada R3T 2N2"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Scott A.","family":"Hatch","sequence":"additional","affiliation":[{"name":"Institute for Seabird Research and Conservation, Anchorage, Alaska, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John R.","family":"Speakman","sequence":"additional","affiliation":[{"name":"Institute of Biological and Environmental Sciences, University of Aberdeen, Aberdeen, Scotland, AB24 2TZ UK and State Key Laboratory of Molecular Developmental Biology, Institute of Genetics and Developmental Biology, Chinese Academy of Sciences, Beijing, Peoples Republic of China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"237","reference":[{"key":"2021042509513010500_JEB130526C1","doi-asserted-by":"crossref","first-page":"661","DOI":"10.1242\/jeb.200.4.661","article-title":"Heart rates and abdominal temperatures of free-ranging South Georgian shags, Phalacrocorax georgianus","volume":"200","author":"Bevan","year":"1997","journal-title":"J.
