Colchester Zoo has announced it is due to welcome another baby white rhino this autumn.

The news comes just a month after one of the zoo's rhinos, Emily, gave birth to a newborn calf called Lottie.

Now, the zoo have revealed that another rhino, Astrid, is also pregnant, and the new baby is expected to arrive in September or October.

It's a further boost for the zoo's conservation project, with the white rhino still currently classified as "near threatened' on the IUCN Red List due to a combination of poaching and the rise of the ivory trade.

The newest arrival will be the sixth new calf to be born at the zoo since the start of the breeding programme.

The calf has once again been fathered by the zoo's male rhino, Otto.
