Abstract

Human pressure exerts a significant influence on animals and the environment. One of its consequences, plastic pollution is considered one of the major threats to fauna as well as a significant conservation issue. In this research, we examined the global pattern of one example of avian behavior in response to pollution—namely, the incorporation of anthropogenic materials into nests—as well as the existing knowledge on this subject. Based on 25 articles, we studied 51 populations, involving 24 bird species, and checked 10,790 nests; as a result, we found that incorporation of debris is correlated with increasing human influence on the environment, measured as the Human Footprint Index. Moreover, the probability of debris incorporation is higher in terrestrial than in marine species. We also identified knowledge bias in favor of marine as opposed to terrestrial species: namely, marine species attract more scientific attention than terrestrial. Furthermore, research approaches to these two ecosystems differ. Undeniably, the factors which influence debris incorporation by birds, the scale of this behavior, and particular forms of use of debris in bird nests are aspects which require long-term standardized research. This is the first global review paper on debris incorporation by birds to demonstrate a close link to human pressure as a driver.

Resumen (otros idiomas)

Nuestro equipo ha realizado una revisión de los trabajos relacionados con la incorporación de basura a los nidos por parte de aves. La presión antrópica sobre el planeta ha aumentado y la contaminación por plástico es considerada una de las mayores amenazas para los ecosistemas. Creemos que la incorporación de basura (materiales antropogénicos como el plástico) a los nidos es una de las respuestas animales hacia la contaminación por plásticos. Se han estudiado 55 poblaciones de 24 especies de aves distintas. La incorporación de basura al nido se ha observado en el 31% de los individuos que conforman esas poblaciones, respecto a un total de 10790 nidos. Mostramos que la incorporación de basura se correlaciona con el incremento de la presión humana sobre el entorno medida a través del Índice de Impacto Humano (Human Footprint Index). Este comportamiento es una de las nuevas respuestas de las aves en relación a la contaminación desde un punto de vista global. También encontramos que la probabilidad de incorporación de esta basura es más alta dentro de las especies terrestres, respecto a las aves marinas.
