The neurological, clinical and pathological findings and endoparasites in 10 wild tawny frogmouths (Podargus strigoides) presented to the Australian Wildlife Hospital in Beerwah, Queensland during a 28-day period in May 2009 are reported. Affected birds had a history of being found in poor body condition on the ground and unable to fly. Clinical examination revealed paresis with variable but generally weakened deep pain responses, withdrawal reflexes and an inability to perch. Severely affected birds that failed to respond to anti-inflammatory, antibiotic and anthelmintic treatments all had larval Angiostrongylus cantonensis in the brain and or spinal cord, with occasional larvae found in the visceral organs. Other parasites detected included the liver fluke, Brachylecithum podargi, the intestinal nematode, Allodapa suctoria, an unidentified species of Trichostrongylus and unidentified cestodes. Gametocytes of Leucocytozoon sp. were found in peripheral blood smears and low numbers of microfilariae were found in histological sections of various blood vessels of several birds. However, no adult filarioids were recovered. Unidentified subcutaneous mites were identified in the connective tissue of the thoracic inlet. Attempts to treat two birds with ivermectin or oxfendazole-praziquantel were unsuccessful, but a third bird treated with a combination of steroidal and non-steroidal anti-inflammatory therapy followed by moxidectin steadily recovered, such that by 6 weeks post presentation its ability to perch, grasp, fly and judge distances was considered normal and it was subsequently released.

Cryptosporidium meleagridis was detected in an Indian ring-necked parrot using morphological and molecular methods. This is the first time that this species of Cryptosporidium has been reported in a non-galliform host and extends the known host range of C meleagridis.
