Agua Dulce beach is usually a sea of humanity, packed with as many as 40,000 people a day at the height of Peru's Southern Hemisphere summer, which runs from December to March.

The new coronavirus pandemic has changed all that. Peru's President Martín Vizcarra declared a state of emergency as deaths began to mount and ordered people to stay home, largely emptying the beach of people.

In this Feb. 16, 2020 photo, people walk across a crowded pedestrian bridge leading to and from Agua Dulce beach in Lima, Peru. Until the mid-20th century, Lima's lower classes couldn't afford beach-going, said Juan Pacheco, a historian of the city. Road-building to the coast solved that. (AP PhotoRodrigo Abd)

But in recent days, an army of seabirds has claimed the sandy territory abandoned by people. Densely thronged pedestrian bridges are all but empty. Instead of chaotic human footprints, the beach is tattooed with the tracks of gulls and pelicans.

But in recent days, an army of seabirds has claimed the sandy territory abandoned by people. Densely thronged pedestrian bridges are all but empty. Instead of chaotic human footprints, the beach is tattooed with the tracks of gulls and pelicans.

Police officers who recently monitored the beach for unlicensed vendors catering to the crowds now walk along the empty beach to warn off would-be swimmers. Those caught out are usually let go with a warning.

Among the few defying the order was Tomas Cabrera, 86, who sat on a jetty enjoying the rare solitude.
