Current Knowledge of Helminths of Wild Birds in Ecuador

Abstract

Parasitic helminths are diverse in wild birds globally, but knowledge about helminths in Ecuadorian avifauna is still fragmentary. In the present review, records about helminths (Platyhelminthes, Nematoda, and Acanthocephala) in Ecuadorian wild birds is presented. A systematic search was carried out using the PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analysis) guideline to compile and summarize the available literature on helminths in wild birds in Ecuador. Data were obtained from ten scientific articles, eight undergraduate theses, and one doctoral dissertation, published between 1966 to 2022. Forty helminth taxa were recorded and information about the host species, site of infection, and location are provided. Nematodes of the genus Ascaridia Dujardin, 1844 were the helminth taxa with the greatest number of records in birds, parasitizing 16 avian species. Also, the Rock Dove (Columba livia; Gmelin, 1789) was the avian species with the greater number of helminth records (n = 11). This review serves as a compendium for future ecological and epidemiological studies on helminths in wild birds in Ecuador and South America.
