During the period extended from September 1992 till August 1993, onehundred and seventy wild birds (27 Egyptian nightjar, 33 Egyptian hoopoe, 21 buff backed heron, 22 Egyptian kestrel, 21 black winged kite, 27 little owl, 5 eagle owl and 14 barn owl) were collected from Abou-Rawash (Giza),Dikimis (Dakahlia) and Zagazig (SThe present study revealed that the infestation rate with helminths was•57.60%. Trematodes were more prevalent (37.60%) followed by nematodes(25.90%) then acanthocephala (17%).The seasonal dynamics of helminth parasites of wild birds showed thatthe highest infestation rate was observed during Winter (71.40%) followed by Spring (69.60%) then Summer (61.40%) and Autumn (57.9%). The highest infestation rate of trematodes was nearly equal during Summer (45.50%) and Winter (45.20%) followed by Autumnthe highest infestation rate of nematodes was 33.3% during Winter followed by Autumn, Summer and Spring (23.70%, 22.70% and 21.70%) respectively. On the other hand, the highest infestation rate of acanthocephala occured
