A pair of jaguar cubs are settling in to life at San Diego Zoo in California.

The brother and sister, who have yet to be named, were born on April 26 and are currently being kept out of public view.

Once they are more mobile, they will be moved to a specially-built cave with their mother Nindiri so that visitors to the zoo will be able to see how they are getting on.

Senior keeper Nicole Johnston is thrilled with the new arrivals: "We are very excited about this, we're ecstatic. We haven't had babies here in 30 years."

The cubs are very small at the moment, but adult jaguars are the third largest of the world's cats and the siblings can be expected to weigh up to 250 pounds in later life.

They are expected to make their public debut in a few months' time.
