Since 2012, there has been a pair of peregrines nesting at the University of Sheffield. The building where they nest was formerly a church, but is now part of the University and is used as a residence.
This year, the birds raised three chicks, all of whom grew up and fledged successfully. The parents at this nest always make sure their chicks are well fed and well cared for. This year, for the first time, the chicks received a silver band on the right leg and an orange band on the left leg. Previously they did not receive a color band. The black letters on their orange bands are PRF, PSF and PTF, and it is hoped that sightings of the birds will be reported.
I have seen the juvies frequently since they fledged, and on several occasions have seen all three back at the nest at the same time.
At least one of the juvies continues to come home to the nest frequently, including today.
