On the use of anthropogenic materials in nest building of House Wren (Troglodytes aedon), a report from Parque Los Algarrobos, Cumbayá, Ecuador

Abstract

Urbanization has prompted shifts in avian nesting behaviors, with some bird species incorporating anthropogenic nest materials (ANMs) into their nests. This study focuses on Troglodytes aedon (House Wren) in Ecuador, exploring the factors influencing their use of ANMs. Observations in Parque Los Algarrobos revealed a House Wren carrying a piece of transparent plastic, entering a street lamp and emergind from it without the plastic. Additional data from iNaturalist showcased widespread ANM use in House Wren nests across Ecuador.
