This study aims at evaluating the prevalence and density of haemoparasites in a native population of immature and adult male and female birds of Burkina Faso. Protists from the orders Eucoccidiorida, Kinetoplastida, as well as microfilaria were found. During the period from the 27th to the 29th of November 2003, we trapped 110 birds: on 101 sampled birds, 47 harboured blood parasites, with an overall prevalence of infection of 46.5%; 15 birds (14.8%) harboured mixed infections. Haemoproteus (prevalence of infection 30.7%), Plasmodium (13.9%), Trypanosoma (10.9%), microfilaria (8.9%) and Leucocytozoon (5.9%) were most frequently recorded. Occurrence of blood parasites was very high in comparison to that seen in birds from other areas of Africa.
