We have become very accustomed to our female laying a full clutch of four eggs. After all, she has done so since 2007 (she only laid three eggs in 2006 - her very first year of breeding).

Also it could be that the male's fertility will decrease...but hopefully not this year let alone next - which will be their tenth year breeding together, assuming both of them survive into spring 2015.
With luck, and now maybe tempting fate a wee bit, we expect the fourth egg to be laid around Friday/Saturday and if that is the case, full incubation will start straight away.
This allows us to predict when the chicks might appear and when they will be big enough to peer over the front of the platform and be seen from below. Ian Layton, our Engagement Officer, will now be able to start planning the Watch Points that we run each May and June down on Cathedral Green behind the cathedral.
For those of you new to Derby's peregrines these are events where we bring telescopes so that anyone passing by (or coming specially) can see the birds 'for real'. Details of dates etc will appear on this blog nearer the time of course.
