Rhino siblings celebrate first birthday with cake

Two rhino calves have celebrated their first birthday with cakes made of pellets, carrots and salad leaves.

Siblings Markus and Mo were born at Cotswold Wildlife Park, near Burford, last year.

The pair weighed about 70kg (11st) at birth, and now weigh about 500kg (78st) each. Their arrival took the number of rhinos at the park to nine, the most in its 56-year history.

White rhinos were close to extinction in the early 1900s, with fewer than 50 thought to remain in Africa. They are now the most numerous of the five rhino species, but the park says conservation remains vital.
