Raven chicks have been born at the Tower of London for the first time in 30 years.
The four new arrivals began hatching on St George's Day following the arrival of breeding pair Huginn and Muninn at the end of last year.
The Tower usually has six ravens at any time and, according to legend, if they ever leave both the fortress and the kingdom will fall.
Ravenmaster Yeoman Warder Chris Skaife said he felt "like a proud father".
It is not known how long ravens have lived at the Tower but it is thought Charles II was the first to insist there must be at least six.
There are currently seven based at the 1,000-year-old fortress, not including the new family.
Since the birds began hatching on 23 April, they have quadrupled in size from about 8cm (3in) to more than 30cm (12in) in height, having been fed on a diet of quail, mice and rats.
One of the chicks is set remain at the Tower and will be called either George or Georgina because of the date the hatching began.
