Abstract
Blood parasites can have a significant impact on the fitness of avian species. The American Kestrel (Falco sparverius), whose populations are declining the United States, is known to be a host to several parasitic organisms. These include species of the genera Plasmodium and Haemoproteus, both of the order haemosporidia, which can cause organ damage and sometimes death. While studies have been conducted on these parasites in adult kestrels, less is known about their presence in nestlings. Our study explored the presence of Plasmodium ssp., Haemoproteus ssp., and other haemosporidia in American Kestrel nestlings. Blood smears were taken from nestlings within the Treasure Valley area and Camas Prairie Centennial Marsh. These samples were then examined under a microscope for the presence of erythrocytic parasites. Pathogens were identified by referencing images of positively identified specimens from previous studies. The findings of this study will increase understanding of pathogens in a vulnerable life stage of kestrels.
