Please note: I have a Schedule 1Licence to photograph at this Peregrine nest site.

The latest development is not a good one but it's nature in the raw. Having been away for the Easter weekend, I returned to the nest territory at the first opportunity, full of anticipation and without any doubt that the falcon would be sitting her clutch of eggs. It was a shock when I peered on to the ledge to see it vacant with no sign of a Peregrine. I studied the nest scrape and could see no sign of eggs either. I waited and waited but still no bird came to the ledge but after a while I did see both birds who flew from beneath me. At this point it became obvious that there was something seriously wrong and the eggs had probably been predated, the only conclusion that I could come to. I remained in the hide for more than 3 hours though, needing to study the behaviour of the adults. Eventually the falcon came in but avoided the nest ledge. She flew from a spot where she had just been feeding, her crop was bulging with the meal and I watched her wipe her beak on the branch that she was perched on. Having noticed last week that she was really quiet, almost secretive, now she was noisy, again and calling for her mate and also using the breeding call. My one and only hope is that she will go on to produce another clutch of eggs but if she does, will these also be predated? I can only guess as to the culprit but my money would be on the Ravens that I have seen and heard constantly this year. The falcon made no attempt to fly to the nest ledge but instead flew from her tree perch on to a favourite rock on the quarry face where I have photographed her before. Both were perched regularly there at the beginning of March.

I visited again yesterday and it was probably one of the most interesting of the season so far. It wasn’t all about Peregrines though. When I arrived I was pleased to see the falcon standing on the nest ledge, this is a sure indication that she is going to try again and lay another clutch of eggs. However after just a few minutes she flew out of the quarry and out of sight. Then a bird arrived and without me getting a proper view, landed on an old Raven’s nest to the left, but not far from the normal breeding ledge. I trained my optics there and I was surprised to see, not a Peregrine but a female Kestrel. She was clucking in breeding display and bobbing up and down excitedly, surely a sure sign that she is interested in breeding here. Kestrels are known to not only choose a rock ledge as a nest site but they also like to use disused corvids nest so this would normally constitute a perfect nest site. But so close to the Peregrines nest ledge, surely there is bound to be conflict. After flying from the ledge it perched in the nearby oak tree and remained there for an hour or so, even having the audacity to use the Peregrine’s favourite perch. Later, after well over an hour, I heard the clucking call of a Peregrine and the female flew in. The Kestrel, even though well aware of the much larger bird of prey, hardly reacted. With the Peregrine now on the nest ledge, I had the pleasure of having two magnificent falcon species in front of me. The Peregrine worked on her nest and the Kestrel then flew on to her chosen ledge and began to display and call in a very animated way. This is all very interesting and I look forward with a lot of anticipation to discovering the outcome of this alliance. Will they tolerate each other?
