In this episode, we go in search of the native wildlife that lives tooth-to-jowl with Longleat’s impressive exotic animal collection. The park's head of forestry, Jim McConkie, is trying to capture an image of wild otters thought to inhabit a river on the estate, and he has roped his children in to help. They find evidence of crayfish, one of the otter’s favourite snacks, but can they capture this elusive, nocturnal predator on their camera traps?

Senior keeper Ian is a keen photographer and birder. He has snapped a true rarity feeding at his garden table – a songbird that hails all the way from the Far East. But can he photograph red kites, the majestic birds of prey, scavenging for supper from the leftovers of the lion feed-up?

Red, the male Amur tiger, has been behaving badly around a few visiting vehicles. The team have a new training regime to get him back on the straight and narrow, but will he earn his meaty reward, or is his taste for cars too strong? Meanwhile, Kate is with another of the park’s big cat family as she checks on the mobility of female cheetah Xena. Born with a growth abnormality in her legs, Xena had to be hand-reared. It’s an emotional moment as this cat, who has been through so much, shows that she has plenty of gas in the tank.

And Jean Johansson joins keeper Sophie to weigh the park’s elderly Asian elephant. Anne might be in her sixties, but at just under three and a half tons, she still packs some muscle. Show less
