Haemosporidian infection in hummingbirds has not been studied in agroforestry or urban areas of the Eastern Andes' western slope, in the department of Santander, despite the existence of evidence of this in other groups of birds. To detect and identify the causative parasites of haemosporidium infections, we took blood samples from the jugular vein of hummingbirds in six locations. PCR carried out the diagnosis of the infection, and the identification of the parasites was made from sequences of the mitochondrial gene Cytochrome b (Cyt b). 86 blood samples were obtained from 20 species of hummingbirds. The prevalence of infection, in general, was 43 %, and in 18 % of the infected samples of Rufous-tailed Hummingbird (Amazilia tzacatl), sequences of HUMHA4 lineage from Haemoproteus archilochus were identified. The presence of H. archilochus in A. tzacatl is reported for the first time in Colombia using molecular biology techniques. This parasite could be implicated in the haemoproteosis of hummingbirds in the country.
