Blood parasites of some columbiform and passeriform birds from Chile

Ninety-one birds of 23 species from Chile were examined for haematozoa; 13 birds of seven species harbored species of Haemoproteus, Leucocytozoon, Plasmodium, Trypanosoma and microfilariae. Haemoproteids (representing four species) were the most common parasites and occurred in 10 of the 13 infected birds.
