52 captive falcons out of 3,988 (1.3%) raptors microscopically examined for intestinal parasites in the Middle East proved infested with hairworms (capillariid parasites). 26 of these (50%) showed concurrent parasitoses. In the group of 26 falcons diagnosed with capillariosis as sole infestation (50%) compatible clinical signs such as anorexia, weight loss, weakness, dyspnoea, regurgitation of food and blood, diarrhoea and dark tarry faeces, were recorded. These birds were treated intramuscularly with ivermectin at doses of 2 mg/kg. In fecal samples examined 10- 15 days later, the eggs of capillariid parasites had disappeared, in association with complete clinical recovery.
