Simba the lion celebrates 13th birthday at Rio zoo

The long-lived lion enjoyed a delicacy made out of meat blood, meatballs and chicken as visitors sang 'Parabens pra Voce', the Brazilian version of 'Happy Birthday to You'.

This birthday celebration is part of a program adopted by BioParque do Rio focusing on animal welfare, creating more dynamic routines for animals and satisfying the behavioural needs of each species.

Environmental enrichments, as they are called, promote challenges and encourage the exploration of new flavors and sensations.

According to biologists at the zoo, the stimuli created by this environmental enrichment gives the animals the opportunity to behave similar to how they would in nature.

After the renovation that transformed the old zoo into BioParque do Rio, Simba was given an enclosure specially designed to recreate his place of origin as faithfully as possible.
