The main mortality for these young birds comes after they leave the nest. At this stage there are many risks the novice juveniles have to face and it is not surprising that some don't make it to adulthood.
When you think about it, our adult pair only has to produce two offspring which go on to breed themselves to keep the population stable. Currently, urban peregrines are increasing across the UK so clearly pairs are producing more than two successful offspring during their lifetimes. The situation is quite different in some parts of the uplands of the UK such as the Peak District where persecution of many species of raptor, illegal as it is, continues unabated.

After a short delay, the last egg hatched last night (May 6th) about 8 pm.
Many thanks to all our dedicated commentators who kept vigil and reported what they saw.
