Ely, who is between 43 and 45 years old has lived at the San Juan de Aragon zoo in Mexico for over a decade.
Ely, trapped in a Mexico City zoo, has been caught ramming her head into the enclosure that has trapped her for 13 years.
But Mexico’s Supreme Court has this week ordered the zoo to work on implementing steps to boost Ely's health, as reported by CNN.
She added that Ely seemed to improve after more elephant friends were added to the enclosure - demonstrated with her new vocalisations.
Diana Valencia, founder of the animal rights group Opening Cages and Opening Minds, said: "It really moved me to see the state that she was in, it tore my soul and I made Ely a promise.".
