Ringing of Peregrine Falcons

The annual visit to ring the Peregrine chicks was on 23rd May. The 4 chicks which were about 3 weeks old were all healthy. We believe there are two males (which weighed 455g & 595g) & two females (weighing 750g & 770g). Thus there was quite a size difference between the smallest & the largest. However, the smaller of the two males is also probably the youngest of the brood & has some catching up to do. Their wing feathers were just beginning to show but will sprout rapidly over the next few days. They develop extremely quickly.
