A total of 641 birds representing 135 species of 25 families from Noel Kempff Mercado National Park in west-central Bolivia was examined for hematozoa; only 33 (5.1%) harbored blood parasites. Microfilariae were the most commonly encountered hematozoans, followed, in numerical sequence, by species of Haemoproteus and Plasmodium; Trypanosoma, Atoxoplasma,(More)
The literature pertaining to the prevalence of avian hematozoa in the Neotropics, together with unpublished records from the files of the International Reference Centre for Avian Haematozoa, has been examined with respect to the distribution of parasite genera by host family and region. The blood parasites of 35555 birds of 955 species (80 families)(More)
The 34 valid species of avian Plasmodium are listed with their authorities and type-hosts. Plasmodium species are also listed by the avian family in which they occur and by the number of avian families and species which they parasitise. A key to the subgenera of Plasmodium occurring in birds is presented. The distribution of the parasites by the Wallacean(More)
The prevalence of avian hematozoa in 1791 birds of 80 species and 22 families from Jamaica was determined. Species of Haemoproteus were the most common hematozoan encountered. Species of Leucocytozoon were diagnosed only in three over-wintering North American migrants and the genus was absent in native Jamaican birds. The low prevalence of infection (7.4%)(More)
We examined associations among parasite infections, secondary sexual traits and testosterone in male red-winged blackbirds sampled at the start of the breeding season. Parasites quantified included ectoparasitic lice and mites and endoparasitic blood protozoans, nematodes, trematodes and cestodes. Secondary sexual traits that we quantified included body(More)
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(More)
