Birds kept in captivity are subject to various diseases that affect their well-being, with parasites being among the most common. The aim of this study was to report the occurrence of endoparasites in the feces of birds kept in captivity at Fortaleza Zoo, using the Willis Mollay and Hoffman techniques. Of the samples analyzed, 50.98% were positive for endoparasites, including the suborder Coccidia, the genera Capillaria spp., Strongyloides spp., Ascaridia spp., Libyostrongylus spp., cysts of a specific parasite of Ostriches, Balantidium spp., the Strongyloidea superfamily and cestodes. In conclusion, the wild birds in the zoo investigated had a diversity of endoparasites and a considerable infection rate.
