In parrots (Psittaciformes), seven nematode species of genus Ascaridia have been found so far, both in wild birds and in birds in captivity. Five species are specific for parrots: Ascaridia hermaphrodita, A. sergiomeirai, A. ornata, A. nicobarensis and A. platyceri. Two species: A. galli and A. columbae, that infect gallinaceous and columbiform birds, respectively, were found also in parrots. On the basis of data from the literature and our own observations the taxonomy, synonyms and list of definite hosts of these nematode species were reviewed. The morphometrical features of nematode species were compiled and a determination key was added.
