Peregrine Falcons first nested on Derby's Cathedral, England, in 2006. Our Peregrine Project is now run by a partnership between Derbyshire Wildlife Trust, Derby City Council, Derby Cathedral and the Cathedral Quarter. Here is what's happening in 2017. . .
Herewith the first photo's from last night's ringing of the chicks and further feedback and answers to questions posed in the comments.The top photo shows Martin reaching across to grab the chicks and put them into the red rucksack in which they were lowered to the nave roof, where Ant ringed them.
First then, we seem to have one female and three males. Because of the windy conditions last night (to put it mildly) we carried out the ringing as quickly as we could and only visually checked the chicks leg sizes rather than measuring them. But the consensus was that there was only one female...her feet were much bigger and her tarsus much broader than the other three despite the difference in ages.
The close up below shows one of the males biting Ant as he was putting the ring on! Also see how the dark feather quills are appearing on its wings and tail.
Second: the female falcon flew round the tower calling loudly while ringing was taking place but this is normal. Only minutes after we left the tower and nave roof, the female was back on the platform with her chicks who were again huddled together in the corner of the nest trying to keep out of the wind! Incidentally, last year the male was nowhere to be seen while the ringing was taking place. At least this year he was flying about, albeit further off and silently.....
The four chicks were given orange/red colour rings numbered 03, 04, 05 and 07 (ring 06 broke and was not used).....01 and 02 were the numbers given to the two chicks in 2007 - the first year we put colour rings on...see the photo of 001 in the previous blog entry. A big thanks to Martin and Ant for their services and skills and everyone else who helped us.
