From a Wall Street Journal story by Juan Forero headlined “Colombian Children Survived on Fruit, Nuts, and Wits After Crash in Amazon Jungle”:

The four small children who survived 40 days in the Colombian jungle after the plane they were traveling in crashed made it on a small supply of food scavenged from the luggage as well as nuts and wild fruit found on the forest floor, relatives and the country’s army said.

The father of the two youngest children, Manuel Ranoque, said the eldest of the four children—13-year-old Lesly Jacobombaire—knew about food in the wild, like the fruit milpe and various seeds, and that helped her maintain strength and provide sustenance to her siblings.
