Update 14th April: a bird watcher in North Derbyshire has seen a peregrine with an orange/red colour ring on its leg but he was unable to see the ring number. Could this be one of our cathedral birds? We await further sightings.......
We now have a full clutch of four eggs (video below). This last egg surprised some of us as we thought this year there would only be three. The reason for that is because we thought that incubation had begun in earnest after the second egg, though it may have been the cooler weather which encouraged them to warm the eggs more than normal. (Full incubation begins just before the last egg is due to be laid)
Our thanks to RJ who reported all four eggs visible at 09.19 on April 5th. On checking our recorded footage, it's clear the egg appeared sometime between 10pm on 4th April and 3am the next day. Surprisingly, we could not see the exact moment; it all happened so quickly and under cover of lots of feathers.
The video below shows a moment on 5th April when the female was relieved from incubating the eggs by the male. We see how much larger she is than the male. Notice, too, the somewhat darker shade of grey around his head than she has. The angle they are at does make it hard even for the Project Team members to tell them apart sometimes.
We'll do our best to answer any questions you may have so do please keep on sending in comments.
