Staff and visitors at Marwell Zoo have celebrated Mother's day with a series of adorable new arrivals. 

Among the latest births in Hampshire is a rare female banteng calf, born to experienced parents Jin and Henky.

Banteng are one of the rarest cattle species in the world and are classified as critically endangered.

Native to Indonesia, these incredible animals are threatened with extinction as a result of habitat loss and the illegal hunting trade.

The young calf has delighted guests by playfully dashing around her paddock – while her mother does her best to keep up!

Winnie, a sitatunga antelope, also welcomed a calf this month. Keepers were delighted to discover the surprise arrival nestled safely in the habitat early that morning.

Initially shy, the calf has spent much of its time hiding among the rocks near the pond but is now gaining confidence and venturing out to explore with its mother and the rest of the herd.

With populations declining due to habitat loss and overhunting in West and Central Africa, this birth is an important addition to conservation efforts.

Hoofstock keeper Jamie Hannah said: "Every birth is a significant moment, not just for Marwell, but for the survival of these species as a whole.

"Watching these young calves grow, develop, and interact with their herds is incredibly rewarding, and we’re excited for guests to see them thrive."

Earlier in the year, the zoo’s first-ever coppery titi monkey came along. The tiny infant named Nacho, born to first-time parents Taco and Mr Titi, is thriving under the devoted care of its father, who carries the baby between feedings. Coppery titi monkeys are monogamous, and males take on the primary caregiving role shortly after birth.
