Haemosporidians in Non-Passerine Birds of Colombia: An Overview of the Last 20 Years of Research

The Neotropics are highly diverse in avian species. Neotropical countries contribute a large part of the estimated diversity of haemosporidian parasites reported for the planet's tropical zones. However, sampling is limited and biased, illustrated by only 30% of the genetic records (barcodes) from non-passerines, most of them not linked to a nominal species. This paper aimed to perform the molecular and morphological characterization of the haemosporidians that infect non-passerine birds from Colombia deposited in the biological collection named Grupo de Estudio Relacion Parasito Hospedero (GERPH). We analyzed 1239 samples from twelve biomes and two animal care facilities. Phylogenetic relationships using barcodes and mitochondrial genomes were estimated. In addition, the reports of haemosporidian infections in non-passerine birds from the Neotropics recorded after 1978 were summarized. We reported the presence of thirteen morphological haemosporidian species, four potential new species deposited in GERPH, a host range expansion for two Plasmodium species, and a barcode sequence for Haemoproteus caprimulgi. We confirmed the species associated with 56 molecular lineages reported in other neotropical countries at the genus level. Thus, biological collections and curated databases such as MalAvi are essential to support integrative approaches demanded in modern taxonomy.

Automated summary

This paper aims to characterize the haemosporidians that infect non-passerine birds from Colombia by analyzing samples from different biomes and animal care facilities. Thirteen morphological haemosporidian species and four potential new species were identified, and the species associated with 56 molecular lineages reported in other neotropical countries were confirmed at the genus level.
