Alhue and Mailen were born in captivity, but conservationists hope to free the chicks soon as part of a project to boost Chile's ailing population of Andean condors.
The Andean condor, a type of vulture, is the largest flying bird in the world but its population is considered "vulnerable" by the International Union for the Conservation of Nature's Red List of Endangered Species.
There are just an estimated 6,700 Andean condors living in the wild.
