Territorial expansion of Zenaida auriculata (Aves: Columbidae) in the Brazilian Amazon

Abstract

Birds are considered bioindicators of environmental quality because they are sensitive to environmental changes. The eared dove (Zenaida auriculata) is associated with open areas, has low sensitivity to environmental changes and is widely distributed in Brazil, although it is not typically found in the Amazon region. We analyzed the biogeographic expansion of this species in the Brazilian Amazon through searches carried out on digital citizen science platforms. The records of Z. auriculata were related with the area of accumulated deforestation in the biome. We identified 804 records of Z. auriculata in the Brazilian Amazon, of which 259 were in areas where its occurrence had been previously unknown. We show that the species has been expanding its geographic distribution, clearly overlapping with deforested areas.

“…Inhabits open landscapes, natural or anthropogenic, and is an abundant species widely distributed across much of South America, including some islands , Port & Fisch 2015. In Brazil, it occurs throughout, but is rarer or absent in the best-forested parts of Amazonia , Ortúzar-Ferreira et al 2022. Although it endures hunting pressure in some regions, the species has benefitted from deforestation and increased grain supply from agriculture (Silva & Guadagnin 2018, Ortúzar-Ferreira et al 2022.…”
