Peregrine Data – Chicks

In 2015, a very young male (ringed on 16 May 2014 at St George’s Church, Sheffield) attracted a mature female to the nestbox, where they hatched and fledged three young peregrines. From 2016 to 2019, the adults have successfully fledged a further 14 young peregrines and a fostered juvenile that was relocated from a nest site in Hull.

Since 2016, the juvenile peregrines have been fitted with an orange-coloured Darvic ring on the left leg and a metal BTO ring on the right leg. The orange Darvic ring carries two or three unique numbers/letters to allow identification later in life. When the rings are fitted, the juveniles are also checked to ensure they are in good condition, weighed and measured. This also helps to determine the sex of the juveniles.

The table below shows the data we’ve gathered since 2015.
