During their first flight between the Atacama Desert and the Pacific Ocean, thousands of ringed storm petrels have fallen victim to light pollution caused by the city and industry.

He will face the greatest mystery surrounding this species: despite the hundreds of specimens that fall in the city each year, nobody knows for certain the nesting sites of the species, lost in the vastness of the desert.
