I agree; I'd certainly like to see common hippo back at Chester again. I'd also love to see common hippo return to London Zoo but I don't believe it will ever happen.
Im not sure the foundations of the old hippo exhibit still exist on the Cotton Terraces do they Tim? I can invisage the footprint from old photos however.
Of interest there’s a recent article that ZSL published on the life of Obaysch’s handler when he arrived in the UK. Unfortunately for my sins I can’t seem to locate the link.
