Hi Mark, I was at Leighton Moss this week, unfortunately the Peregrines at Warton Crag have not bred successfully this year. A new male peregrine replaced the bird that died after a collision with a car on the road near to the quarry. The first clutch of eggs was laid around the time the Ravens were fledging and were predated. The peregrines laid a second clutch which suffered the same fate Hopefully the will be successful next season. That is the situation from talking to some of the regular visitors.
