Two baby rhinos have defied the expectations of worried zookeepers by becoming the best of friends.
Keepers at Edinburgh Zoo had been worried that new arrival Bertus would clash with 18-month-old Samir, who arrived in the capital last month. However, since being introduced on June 1, the pair have begun to act more like brothers than housemates.
Despite being young, Bertus and Samir are the zoo's heaviest residents, tipping the scales at more than two tonnes each, and nervous staff had been worried about the potential danger of introducing one into the residence of the other.
They had considered a gradual introduction but after seeing the laid-back nature of Bertus, staff decided to house the two together immediately. And after much trepidation, the keepers were amazed to watch the two immediately become firm friends.
Sue Gaffing, Head Keeper for the rhinos, said: "We've had Indian rhinos at Edinburgh Zoo since 2006 but when our males reach breeding age at about five or six-years-old, they leave to start their breeding life in another zoo collection and are replaced by juveniles.
"In the wild, rhinos are solitary animals and only tend to come together to mate, but while they are young they can live happily alongside each other. But you are never quite sure how a new pair coming from different collections will get on. In the past, there have been dominance struggles but this pair have been totally different.
"Bertus is incredibly relaxed and his chilled attitude has really rubbed off on Samir who was pretty nervous when he arrived. They are now inseparable, following each other around as if they are attached by an invisible rope! It is truly lovely to see and both are obviously enjoying each others company.”
Part of the role staff at Edinburgh Zoo play in the rhino breeding programme is to train new arrivals to allow routine medical checks to be carried out without stress.
Sue admitted that can be a difficult task, adding: "The sheer size and design of a rhino presents its own challenges from an animal management perspective.
"Rhinos have skin as thick as 3cm in places, so simply getting a blood sample can be difficult. We use positive reinforcement training where the animal is rewarded for the behaviour we want. In the rhino’s case this allows us to get blood samples from behind the ear – the area where the skin is at its thinnest - as well as to get them to lift their hooves for inspection as rhinos are notorious for problems with their feet."
