Columba livia Gmelin, 1789 (Columbiformes: Columbidae): agent of change and threat to avian biodiversity in Huánuco District, Peru? An analysis based on the precautionary principle.
An important part of natural heritage is birds of Peru, as they contribute to ecosystem services, as well as being excellent bioindicators for the health of the environment and ecological/environmental change. Peruvian avian biodiversity has registered 1857 species, but there is still no record of invasive alien species (IAS), which merits a control or eradication program. In many parts of the world, pigeons (Columba livia Gmelin, 1789) have been defined and identified as IAS; this is a very important step, because the perspective of the International Union for the Conservation of Nature (IUCN) requires a thorough evaluation in that regard. No one finds it strange that pigeons have taken over public parks. Pigeons do not compete for spaces for nesting with other birds in their environment. Since they share with native birds the transmission of diseases could affect the population of native birds. This deductive trial, in light of the evaluation of the results of investigations of parasitosis in pigeons in the city of Huánuco, Perú, is postulated as a first diagnosis of the change and threat to biodiversity that this species may represent; thus, adding information we would have more security in considering a control program, as indicated by Aichi's goal 9 of the Strategic Plan for Biodiversity 2011-2020.
