Baby elephants at a Bedfordshire Zoo - including one named in honour of the Queen - are ready to receive their royal visitor.
The Queen, accompanied by the Duke of Edinburgh, will open an elephant centre during a visit to Whipsnade Zoo this morning.
They will tour the new home for nine Asian elephants - including an eight-month-old called Elizabeth.
She was born the day before the Queen's 90th birthday last year and was named after the record-breaking monarch.
The custom-designed barn has one-metre deep soft sand flooring and is set in 20 acres of paddocks for the herd.
Asian elephants are considered endangered due to habitat loss, poaching and human conflict, and the Zoological Society of London (ZSL) charity - which runs Whipsnade - is involved in more than 50 conservation programmes to ensure elephants and humans can coexist peacefully.
The Queen, who is patron of the ZSL, will watch the elephant team carry out daily care tasks such as nail filing and mouth care before unveiling a plaque to officially open the new centre.
The centre opens to the public on Wednesday, April 12.
