Hand fed fish and given gentle yet rigorous baths, penguins and other sea birds are slowly regaining their strength at a Peruvian zoo after a major oil spill that claimed many of their friends.

Of about 150 oil-stained birds rescued alive after the January 15 spill of some 12,000 barrels of oil, half later died.

The survivors — penguins, cormorants and pelicans — are being nursed back to health and independence at the Parque de Las Leyendas zoo in Lima.

With oil on their wings, birds cannot fly or feed, and they lose the insulation they need to keep warm.

Even birds not directly contaminated with crude fell ill or died after eating fish that were.

– 'Very stressed' –

At the zoo, the rescued birds are fed fish — for the penguins it is their preferred prey of silverside and anchovies.

They are given a special rehydration mixture through a tube, bathed, and dried with a towel.

"Many of them arrived in very bad condition, which makes it difficult for us to handle them," said Giovanna Yepez, one of the rescuers at the zoo.

"The animals were very contaminated… were very stressed," she added. "It is a very hard job."

But after two weeks of intensive care, the penguins at least "have tripled their food consumption," said Yepez.

"I believe the penguins are on the right track, they are clean and waiting for the impermeability of their feathers to return so they can be released."

Even when the feathers appear clean, the slightest vestige of crude inside the beak "can affect (the bird) through the digestive system, the liver," added veterinarian Giancarlo Inga Diaz, hence the need for patience and thoroughness.

– 'Disaster' –

The spill, described as an "ecological disaster" by the Peruvian government, happened when an Italian-flagged tanker was unloading oil at a refinery off Peru's coast.

Spanish oil company Repsol said the tanker was hit by freak waves triggered by a tsunami after a massive volcanic eruption near Tonga, thousands of kilometers away.

The oil slick was dragged by ocean currents about 140 kilometers (87 miles) north of the refinery, prosecutors said, killing countless fish and birds, polluting tourist beaches and robbing fishermen of their livelihood.

The Humbold penguin — a species classified as "vulnerable" by the International Union for Conservation of Nature — lives in colonies on the Peruvian and Chilean coasts, feeding in the cold, nutrient-rich waters of the Humboldt Current which flows north from Antarctica.

Some 9,000 of the black-and-white flightless birds are known to exist in Peru.

They stand about 50 centimeters tall.

Peru has demanded compensation from Repsol for the spill at its refinery.

Repsol says Peru oil spill will be cleaned up in March
Callao, Peru (AFP) Feb 4, 2022 –

Spanish energy giant Repsol on Thursday vowed to finish by March cleaning up a devastating oil spill that has polluted beaches and killed wildlife.

Almost 12,000 barrels of crude spilled into the sea off Peru on January 15 as a tanker unloaded oil at a Repsol owned refinery.

"We expect that if the weather allows us then, in mid-March" the cleaning of beaches and islands off the coast will be completed, Repsol's environmental security director Jose Terol told reporters.

However, he warned that it would take a little longer to finish cleaning cliffs and rocks that are difficult to access.

"By mid-February, there will already be no more slicks in the sea. In an optimistic scenario, work on the difficult to access areas will be finished by the end of March," said Terol.

Peru's government described the spill — which Repsol blamed on freak waves caused by a volcanic eruption more than 10,000 kilometers away near Tonga — as an "ecological disaster."

The oil slick has been dragged by ocean currents about 140 kilometers north of the refinery, prosecutors said, causing the death of an undetermined number of fish and seabirds.

Peru has demanded compensation from Repsol, and the energy giant faces a potential $34.5 million fine, the Environment Ministry has said.

Even as the Repsol spokesman spoke, a group of protesters from the hard-hit nearby beach town of Ancon gathered with signs and chanted demands outside the plant.

"Repsol accept responsibility", and "Repsol murderer, the beaches of Ancon are in mourning" were among their signs.

"The reason for the protest is that (the oil spill) has left us without work because of this contamination of the sea in Ancon," Miguel Basurto, a 53-year-old motorcycle taxi driver, told AFP.

"We feel outraged because we have no support from the Repsol company. They clean their hands of it, and go away and leave us with all this pollution that affects children and the elderly," said merchant Ana Garrido, 40.

It was the first time since the spill that Repsol let journalists visit its La Pampilla refinery — to see how 90 specialists there are managing the 3,000 people who are cleaning up the spill.
