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 2018, the adults have successfully fledged a further 10 young peregrines and a fostered juvenile that was introduced from a nest site in Hull.

Since 2016, the juveline peregrines have been fitted with an orange colour 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. At the same time the rings are fitted the juveniles are checked to ensure they are in good condition, weighed and measured. This also helps to determine the sex of the juveniles.

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