SOMETIMES, the grass is greener on the other side, as a group of gelada primates discovered at the Dudley Zoo.
The gelada has exchanged houses with the Sulawesi crested macaques to give the nine geladas better access to the vegetation they need for grazing.
The transfer to the grass bank beneath the zoo's iconic chairlift has given Ebano male impressive views from one of the mature ash trees.
Senior primate keeper Jodie Dryden said: "Geladas are the only primate species that graze and love green grass and trees in their new home.
"They have full access to the grass bank, which is very similar to the habitat of their wild cousins, who graze in the mountainous grasslands of Ethiopia.
"It has been a very successful transition and geladas also enjoy seeing our visitors. They are not shy about sitting in the window of their inner study.
