“…Diagnosis of the presence of a gastrointestinal foreign body requires a thorough clinical history and physical examination findings (Miller et al, 2009;Hoefer and Levitan, 2013;Cotton and Divers, 2017). An important method for the diagnosis of a foreign body in the gastrointestinal tract of birds is radiological examination combined with advanced imaging techniques, such as contrast radiography, fluoroscopy, computed tomography, or endoscopy (Miller et al, 2009;Hoefer and Levitan, 2013;Castaño-Jim enez et al, 2016;Cotton and Divers, 2017;Laniesse et al, 2018). Radiographs can provide useful diagnostic information in sick raptors that exhibit vomiting, altered appetite and abdominal dilatation, and can support treatment decisions about birds with gastrointestinal impaction (Applegate et al, 2017).…”
