With tall buildings offering similar benefits to cliff ledges, peregrines have recently been adapting well to a more urban lifestyle. Unusual nesting sites in built-up locations around the UK now include the Tate Modern gallery in London, Chichester cathedral and Manchester's Arndale shopping centre.
Here in Wales our own pair of city slickers have taken up permanent residence in a high-rise nesting site on Cardiff City Hall's iconic clock tower, giving shoppers and workers an opportunity to see these amazing birds of prey soaring above the skyline.
From this week, as the pair prepare to raise their next brood, people will also be able to keep a closer eye on proceedings through a special viewing scheme organised by the RSPB.
Live images from the nestcam will be screened at the nearby National Museum, while later in the year people will be able to watch the fledgling peregrines make their first flights from a special viewpoint on the lawn of City Hall.
