It's time to deck the halls because Ben Fogle and Kate Humble are heading back to Longleat Safari Park for a magical week of programmes.

As far as Christmas wishes go, few are bigger than the one the keepers have had for the last few years – a baby koala. Incredibly, last year that wish came true when Violet gave birth to Hazel. As the first southern koala to ever be born in Europe, she was quite the Christmas miracle. Unbelievably, this Christmas the keepers suspect Maisy may now be expecting too.

Megan McCubbin is spending time with some of the busiest animals of the season, the reindeer. Both male and female reindeer have antlers, one of the few deer species that do. In fact, it's a challenge for Megan to avoid them when taking Reuben for a walk because his antlers are on course to grow over a metre in length.

It's wildlife photographer Hamza Yassin's first Christmas at the park, and he is being put to the test by Animal Park legend and fellow photographer Ian Turner. Hamza has the challenge of following the feeding truck as it does its morning rounds to feed the lions, tigers, cheetahs and wolves. The question is, will he be quick enough to get the killer shot worthy of the annual Christmas card?

Also today, there is a monumental release of native wildlife back to the estate, as eighteen water voles get to explore their new home down at Half Mile Lake.

For the last time in this festive series, Ben Fogle and Kate Humble are at Longleat Safari Park to conclude a magical week of programmes.

Today, Ben and Kate are set a secret mission to find out which animals should go on the ‘naughty' list and who should go on the ‘nice' list, but with animals including ferocious tigers, enormous rhinos and naughty monkeys, how can they possibly decide? And what will be in store for the animals on Christmas morning?

Out in the safari park, the camels receive a surprise present in the shape of a new member of the herd, but it's a gift that needs to be handled with care. Neils is a young male and is being introduced to a herd of females and an older male. The hope is that in time they will accept the young boy, and he will ultimately become the new breeding male. But these festive introductions could easily turn sour if the herd attacks the youngster.

With Christmas day just around the corner, there are still a few animals that Megan McCubbin needs to deliver some festive cheer to, with the goal of enriching the senses and setting them puzzles to solve. The ferrets get served a helping of eggnog, and the turkeys get weighed, but don't worry, they are not on the menu. This weigh-in is to check they are happy and healthy, but they are still reluctant to jump on the scales.

Christmas is the most magical time of year at the park, and to round off the series, the passionate and hard-working keepers reflect on the wonderful privilege they have of spending so much time with the animal families that bring us so much joy.
