Xita, a tiny marmoset monkey with sad brown eyes, clutches her newborn tight. Both are fighting for their lives.

Vets working at the Clinidog clinic in the Amazon city of Porto Velho believe the mother and baby were run over by a car as they fled fires raging across the world’s largest rainforest.

“She arrived stressed, screaming and smeared with blood,” said Carlos Henrique Tiburcio, the owner of the clinic, as he wrapped the pair in a small, white cloth.

Creatures of the Amazon, one of the earth’s most biodiverse habitats, face an ever-growing threat as loggers and farms advance further and further into the rainforest.

In the dry season, ranchers and land speculators set fires to clear deforested woodland for pasture. Blazes can rage out of control, fuelled by the swirling wind and dry foliage.

Animals flee the flames, with the weak and dying among them arriving at Tiburcio’s clinic where four volunteers work tirelessly to save them.

“This time of year, when fires are constant due to the absence of rain, the animals seek shelter in desperation to escape death and end up in the city, putting themselves at risk of being run over or captured,” said Marcelo Andreani, whose job is to rescue injured animals and bring them to the clinic.

“Human respect for nature is ending,” said Andreani, who works for the state environmental police.

An anteater arrived with a broken left paw after a clash with a fierce porcupine. The patient had been found hiding in a garage. The vets think she might have been fleeing fires as anteaters rarely turn up in the city.

After surgery, one of the vets took Linguaruda home to keep a closer eye on her recovery. At one point, she climbed into the sink to rest.

In five days, Linguaruda was strong enough to return to the wild – the best outcome her rescuers could wish for.

“Our personal and professional satisfaction is immense when we manage to save a life, especially when we manage to rehabilitate an animal and return it to nature,” Tiburcio said.

“I look at the sky and say, ‘Thank you, Father, for everything you did for [me] to be the Lord’s instrument.”

Linguaruda was freed near a forest trail, where she eagerly clambered among the trees once more.
