Avian haemosporidian from the genera Haemoproteus and Plasmodium are a diverse and widely distributed group of vector-borne blood parasites. These parasites can have negative effects on bird survival by influencing several aspects of their life cycle, causing different clinical signs and even death. Colombia has the widest range of bird richness throughout the globe; however, the associations between haemosporidian parasites and wild birds in different ecosystems remain poorly explored. Within this frame of reference, the objective of the present study was to identify and understand haemosporidian associated with resident and migratory wild birds and their lineages in northeast Orinoquia region, Colombia. Birds were captured in 8 localities and blood samples were collected, identifying the presence of haemosporidian parasites through morphological and molecular analysis of the mitochondrial cytochrome b gene. Blood samples from 233 wild birds (86 species) were analyzed for haemosporidian parasites. Sixteen individuals (6.9%) from 15 resident and migratory species were positive for Haemoproteus or Plasmodium. Fourteen haemosporidian lineages were identified, five of them reported for the first time. These new lineages are reported in four resident birds and one boreal migratory bird (Parkesia noveboracensis). This study is the first developed in the department of Arauca and contributes to the knowledge of haemosporidian lineages and their interaction with wild birds in the Colombian Orinoquia region and South America.
