Four indigenous children are doing 'very well' after surviving 40 days in the Colombian Amazon, authorities said on Friday as they were released from a military hospital.

Lesly, 13, Soleiny, nine, Tien Noriel, nine and one-year-old baby Cristin were the only survivors after the small plane they were flying in crashed in the jungle in June.

All three adults on board, including their mother, died. The eldest sister has been credited with keeping her siblings alive throughout the ordeal.

The four were discharged from the Bogota hospital on Thursday night, said the Colombian Family Welfare Institute, which will temporarily take custody of the children for six months until a permanent decision is taken on their care.

"They have recovered size and weight, really they are very well," said Astrid Caceres, the director of the institute. "The second phase of caring and protecting them begins.

"We're entering a transitional phase for the protection of the children."

The children show no physical effects from the 40 days they spent wandering the Amazon, she said, and even little Cristin is "completely recovered in terms of physical development".

The children appeared emaciated in photos taken shortly after they were found, and in the hospital they were given food typical of the Huitoto Indigenous group to which they belong, such as cassava flour.

Relatives say the children managed to survive thanks to Lesly's deep knowledge of survival in the jungle, with its many dangers - including snakes, predatory animals and armed criminal groups.

It took nearly 200 military and indigenous rescuers with search dogs to track them down.

After their rescue a custody battle ensued between the maternal grandparents and the father of the two younger children.

The siblings will live with other children in a shelter. Ms Caceres said the children will be in a rural area where they will feel "comfortable".
