Three peregrine falcon chicks have successfully hatched on the ledge of a city centre building belonging to Nottingham Trent University.
Experts had been concerned about the effect of the cold weather on the eggs.
The parent birds, now feeding their brood, have attracted a global following, as their lives are recorded with a live camera and are the subject of a blog.
Sarah Thorp, Environmental Projects Officer at Nottingham Trent University, said the chicks seemed to thrive in the location. She said:
''It's fascinating to watch them and see them interact with each other.''
