Look for birds on the east (rear) face of the tower where the nest platform is located half way up.
Or look higher up a ledge of gargoyles near the top.
Three web cameras now let you monitor their progress, day or night, all year round.
Adult peregrines can be seen on most days around the tower at Derby's Cathedral Green, or perched high up on the blue lettering of nearby Jurys Inn Hotel.
Even outside the March-June breeding season they are often visible via one of our three webcams.
Please Note: we are aware of connection issues which have affected our live cameras in recent weeks.
These are being investigated as a matter of priority as other services are also being affected.
Important: Please see the Derby Cathedral Peregrine Project blog for important news about the webcams.
