One of the joys of studying wild Peregrines (and there are many), is the sense of anticipation as to what one might witness during that next field trip. Such was the case, when we first discovered, and filmed, one of our study pairs raising three Herring Gull chicks.
We had been fortunate, to watch a video of the same behaviour, filmed by talented amateur cameraman P. Chaney having been discovered by R.Baker. This footage was captured on the Dorset coast, but not for one second, did we ever expect to see the same for ourselves.
It was on the morning of May 30th, that we had our first encounter. I was in the company of Steve Watson, a good friend of the group, who had journeyed down from Gloucestershire for a couple of days birding. We arrived at the site, for a routine check on the breeding status of the resident pair. After briefly scanning the home cliff, I located the falcon.She was clearly brooding chicks, as I watched through the scope, my jaw dropped, as the head of the first baby Gull appeared. I turned to Steve, and relayed what i’d seen, he bundled me away from the eyepiece,and after a few seconds he too got his first glimpse. I’ve never heard Steve swear before, but he turned to me and simply uttered a couple of words that i couldn’t possibly repeat here. We watched for a couple of hours, after which we were forced to leave, to fulfil another appointment. We returned in the evening, with both Greg and his camera to capture the first video.
Our next visit to the site, was equally special. The young Gulls are thriving and as you will see in the following footage (which was filmed on the 12th of June), we managed to capture the youngsters being fed by a very confused Peregrine. We hope you are as astonished with what we were fortunate to witness.
Cheers for now

Good camera work but how can you or anyone enjoy watching this? It’s completely unnatural behaviour almost certainly caused by human interference – someone removed or destroyed the Peregrine eggs and replaced them with those of Herring Gulls. The adult falcons can’t tell the difference so continued incubating as if nothing had happened. Anyone monitoring the site would have been fooled into thinking everything was fine, for weeks. And I fear this situation will end in tears. When the falcons cease feeding the chicks with small morsels, how are those youngsters going to react when presented with a whole Pigeon carcass? Won’t be much fun watching them starve to death! 😦

We do not believe this was caused by human interference as the Pair were incubating in another Eyrie further up the cliff face only a week or so before. It is thought she has relocated to a disused eyrie and taken over the incubation of these. We fully understand your comments and are already are aware of the results based on a 2001 report by R.Baker in Dorset (British Birds). It is not so much a case of enjoyment, but astonishment. Would you suggest intervention at this point – We don’t know the answers to lots of questions, but thought it needed to be documented and shared (this would be even more so pertinent if human intervention had been the case, if only to raise the profile of Wildlife Crime with the General Public) – sorry if it may have caused any offence to you, none was meant.

Thank you for your reply. No offence taken but your choice of words were, I believe, inappropriate. I note that you’ve now revised the text to correct this. Why would a pair of Peregrines leave their own eggs and move to a nearby site containing Herring Gull eggs? Doesn’t make any sense to me.

When an eyrie fails, eggs chilled or possibly infertile it has been recorded and witnessed that they will often visit previous ledges. In this case a gull has nested on such a ledge. Hope this helps clarify what is a possible theory. We do not claim to know the answer.

Wonderful and truly amazing ! I can’t wait to see the outcome as the chicks fledge. The tiercel will be dwarfed by these huge youngsters soon 🙂

Again I’m afraid the outcome will not be a good one – see report by R.Baker (British Birds) to a similar event in 2001/02 – but we had to document this no matter the outcome.

Wonderful footage. Nature is always full of surprised. Is it a Peregrine pair or just an individual feeding the chicks?

Opening shot is the Adult male (Tiercel) and the close up head shot the Falcon. Thanks for your comment. Shot with scope and with handycam attached. I find it the only way to shoot animals 😉

I am happy to email a copy of the ‘British Birds’ article mentioned by SWP to anyone interested but I would just say that it was edited by BB and the fact that the ‘event’ was vidoed by Phil Chaney, a fellow birder from Somerset,was not included.

Hi there, your prediction of a grisly ending to the tail seems entirely probable, but did you get any confirmation on follow up visits? It would be interesting to know how far the parenting instinct took this alliance before something more visceral kicked in…

The dilemma of ringing these chicks was one we thought of. This would have at least made them identifiable on the cliff or as recoveries. We decided against interference but unfortunately can offer no more detail post fledging…

Amazing occurrence. I don’t understand some of the reaction in the posts above. The compulsive need/want to parent is a fairly universal urge amongst many animals including humans. This need often leads knowingly to adoption. I’m not suggesting in this case it’s an intellectual decision but who’s to say answering the call to nurture isn’t behind this and other examples of fostering even amongst birds hosting Cuckoo chicks. It’s easy to dumb this down with terms like “instinct” which really explain nothing. Very interesting event.

Thanks Beachboy, it was fascinating to observe them, probably a once in a lifetime experience but who knows.
