STORY: The population of sea lions numbered about 110,000 in Peru in 2020, mainly in the coastal region of Ica and the Paracas nature reserve, according to Oceana, an international organisation dedicated to protecting the oceans.
In recent weeks, crews from Peru's National Forestry and Wildlife Service, in protective suits, gloves and masks, have collected and buried hundreds of sea lions from several beaches along Peru's central coast.
"What we remember initially started with pelicans last year is now affecting these marine mammals," Javier Jara, a veterinarian with the service, said.
Peru recorded its first case of the virus in November in birds in the north of the country.
Since then it has killed around 63,000 birds, mostly pelicans, according to government data.
Since the beginning of 2021, bird flu has ravaged the world, killing more than 200 million birds due to disease or mass culling, the World Organization for Animal Health has said.
In South America, bird flu cases have been detected in Ecuador, Bolivia, Chile, Paraguay and recently in Argentina and Uruguay.
In Brazil, the world's largest poultry exporter, there are still no confirmed cases.
In Chile, health authorities last week detected the first positive case in a marine mammal, a sea lion on a beach in the north of the country.
