Rats have been labeled a "ticking time bomb" for the ecosystems along the coast of Peru, as they pose a significant threat to endemic wildlife, particularly sea birds like the zarcillos and penguins. Experts and environmental organizations, including government bodies, have begun developing projects aimed at eradicating these invasive rodents to safeguard local species. This initiative highlights the urgent need to address the environmental impact that such invasive species have on native fauna.

At dawn, researchers observe the behavior of zarcillos in their natural habitat, noting the alarming decline in their population due to predation by rats. Biologist Susana Cárdenas, who leads the Punta San Juan Program, emphasizes the crucial role of controlling rat populations to protect the marine biodiversity of the region. As these small creatures continue to threaten local bird species, conservationists are taking proactive measures, such as setting traps, to mitigate their impact.

The erosion of biodiversity along Peru's coast from invasive rats exemplifies a broader ecological issue faced by many regions worldwide. The combination of habitat loss, introduced species, and climate change poses a severe challenge for conservation efforts. Initiatives to remove these invasive rodents could serve as a model for similar challenges faced in other parts of the world, emphasizing the need for global cooperation in wildlife preservation and ecosystem management.
