Silverback Oumbi Worried

Work is continuing on the new Orangutan House and adjoining buildings. Today the roofers were up there and Oumbi was very concerned, he was the same when the big crane was there. Shufai kept coming out to check too. Oumbi had been barking alarms and charging. He did calm down thankfully, but things moving high up on the skyline clearly worry him. #westernlowlandgorilla #gorilla #apes #greatapes #twycrosszoo #primates #silverbackgorilla #silverbackoumbi #silverback
