The Nottingham peregrine falcons have been nesting on the Newton Building at Nottingham Trent University for the last 10 years.
Around this time of year the chicks need to be ringed to help ID them when they are older and track their movements.
This year, four chicks were ringed, with the biggest normally being female and the smallest normally being male.
Peregrine falcon numbers crashed in the 1960s due to the impact of pesticides. They have now increased slightly in numbers, to about 1,400 breeding pairs in the UK but their recovery in some areas is still held back by illegal persecution.
They carry one of highest standards of legal protection and if peregrines are disturbed or harmed, perpetrators can face fines up to £5,000 and even imprisonment.
Today, peregrine falcon populations in Britain are slowly recovering thanks to their protected status and the banning of dangerous pesticides.
When the peregrine falcons started using the ledge of the Newton Building as a nest site a few years ago, Nottingham Trent University and Nottinghamshire Wildlife Trust decided to install a camera for security reasons.
The aim was to stop egg thieves and protect the raptors from intruders.
