A total of 809 birds from Senegal, including 43 species and 21 families, were examined for hematozoans; 93 birds (11.5%) harbored blood parasites, with only 7 (7.5%) harboring mixed infections. Species of Haemoproteus occurred in 81.7% of the infected birds while species of Plasmodium, Trypanosoma, microfilaria and Leucocytozoon were encountered less frequently. The majority of the sample was composed of species of ploceids and estrildids and blood parasites were most prevalent in the colonial-nesting ploceids. Prevalence of blood parasites in Senegal was low in comparison to that seen in birds from other parts of Africa.
