Month: July 2025

Immaculate birds, constant activity and plenty of noise!

I might be a raptor nut but I love terns too. Wales is a bit of a “tern desert” and with one exception (little terns near Prestatyn) one must visit Anglesey to connect with them. Cemlyn Bay on the north coast is the Welsh tern H.Q. with its large sandwich tern colony, alongside smaller numbers of arctics and commons. On a good day one might see a roseate as well. I can confidently say that a visit to Cemlyn is one of the finest wildlife experiences in Wales. But your timing needs to be carefully judged.

The ideal time is just after the tern chicks have fledged because their parents then guide them to the shingle spit which divides the lagoon from the sea, away from the chaos of the nesting islands. But leave it too late and the whole damn lot of them will have left altogether! Last year I arrived on July 23rd to find that most had already gone, whereas in 2020, August 1st was just perfect.

This year I discovered that the North Wales Wildlife Trust helpfully posts updates on the progress of the colony on its website. It suggested that a visit sooner rather than later would be advisable. So I headed north late on July 12th. The following morning I was there bright and early for the full tern colony experience. Immaculate birds, constant activity, and plenty of noise! Despite nearly 50 years of birding experience I have never totally got to grips with the differences between arctic and common terns. Many birders refer to them as “comics” because they are so difficult to separate. However after this visit I think I’m getting there! Sandwich terns are comparatively easy, and I have so rarely come across roseates that identifying one would be a real adventure (but see this post…..).

As it happened I picked up my first roseate quite quickly. It was visible on and off on the near edge of the main nesting island during the morning, and around lunchtime there were two together. I was able to get a few (rather poor) photographs of them. One of the tern wardens arrived soon afterwards and I was able to point them out to him. How about that for confidence! But as he had been seeing them throughout the breeding season he wasn’t too excited. He told me that one pair had attempted to breed early on but had failed, while he was still hoping that another pair would soon appear from the denser vegetation on the island with a youngster.*

For some time prior to that I was in “spray and pray” (or point and hope) mode. In other words: point your camera at a bird in flight, press the shutter button and try to follow it. This seems to me to be rather a technical task more dependent on luck than anything else, and I find it rather unsatisfying.

Arctic tern …………probably………

What I found more challenging was to place the terns within the landscape to give them some kind of context. At low tide, during the middle of the day, many roosted on the beach or on rocky outcrops along the foreshore. One could thus place them within an unspoiled landscape, suggesting that all is well with the world, which is perfectly valid. Alternatively, shooting from a different angle, one could set them against the massive hulk of Wylfa nuclear power station , now disused, only a couple of miles away. The viewer can then make up their own mind about the state of the world.

With ……… or without ……..?

As I mentioned this was during the middle of the day when the sun was at its highest. This is never a good time to take photographs of anything in summer so one does one’s best to compensate for it at the processing stage. Some of the newer features in Lightroom are excellent for this – in particular the ease with which “objects” can be selected and processed individually without affecting the rest of the image. And “denoise” is excellent, although rather slow on my PC.

Another thing I noticed very clearly was how the apparent colour of the power station changed during the course of the day. Its colour scheme at breakfast time matches the colour of the lichen covered rocks on the foreshore very well, and it would be uncanny if this had not been part of its design. I included a photograph illustrating this in my book “Wales at Waters Edge”; I wonder if anyone noticed….? But by early afternoon the plant was naturally bathed in blue light and looked quite different. To put it more technically, the colour of sunlight is towards the blue end of the colour spectrum (“cooler”) during the middle of the day, while it is “warmer” earlier and later. This is well known among photographers but I have never known it being demonstrated so clearly as it was that day.

Arriving as early as July 13th was, in the event, quite a close shave. A note on Facebook from the tern wardens on the 18th said that most of the terns (95% of them) had already left the area. I wish them good luck on their travels and hope they make it back to Cemlyn next year.

*N.B. : The second pair also failed …..

Little and Large

As I may possibly have previously mentioned ( see this post, or this post for example) I’m a bit of a raptor nut. My favourite species is the peregrine. In 1979 I did my first species protection contract for the RSPB, keeping watch on two peregrine eyries in north Wales that were regularly robbed by falconers. The nesting sites were very distant and I barely saw the birds themselves! Most of my work consisted of driving a particular stretch of road looking for dodgy characters and checking off car registration plates against a list I was provided with. However things improved in the early 1980’s when I monitored peregrines (and other species) on the Isle of Mull and northern England for the RSPB; then in Ceredigion as a volunteer in 1983, and the following year just inside the Arctic Circle in Greenland. My activities then gradually shifted towards a full-time photography career and I soon had no time for birding. Now I have more time again and I’m spending more time watching and monitoring raptors.

Enough of the background! My point is that I know my peregrines.

I was surprised to discover in 2021 that peregrines had returned to nest in inland Ceredigion and I began occasionally visiting two cliff nesting sites near my home. In 2023, one pair reared three young and did so again in 2024. This year I visited the cliff at the beginning of May, then again at the end of the month. It was clear from the latter visit that they were using the usual ledge (an old raven nest) and probably had small young. By June 19th two young were visible and the interesting thing was that one appeared to be up to 14 days younger than the other. One looked full grown although it still had flecks of white down adhering to its body; it was exercising its wings vigorously. Comparing its appearance to the illustrations in “The Peregrine Falcon” (Derek Ratcliffe) it looked about five weeks old. The other was small and downy all over with stumpy little wings, and looked about 3 weeks old. .

My next visit was on June 30th. When I arrived both young were on the nest together; they were pretty much identical in appearance. It looked as if the younger bird had “caught up” with its sibling. Very soon one flew from the nest and landed clumsily in the ivy above the nest. After some time it flew and visited a number of different ledges before landing in full view of the other youngster, as seen in the main picture. In flight it looked confident and skilful. How long ago it had fledged I couldn’t tell. The nestling was clearly desperate to fly, standing on the edge of the nest, screaming and flapping its wings furiously. Several times it appeared to run from the back of the ledge to the front, and then slammed on the brakes. It just wasn’t confident enough to take the plunge into the outside world. After a while one of the adults arrived carrying prey, ready plucked and glistening bright crimson in the sunshine. It dumped the prey on the ledge next to the fledged youngster, leaving its poor sibling flapping and screaming even louder!

I was able to document this photographically, but I must emphasise that I was very distant from the cliff to avoid causing any disturbance. To have done so would have been illegal and also pointless, because natural behaviour patterns would have been disrupted. The photos themselves are not great, having been taken from afar and then cropped drastically. But they do the job.

Derek Ratcliffe’s masterwork “The Peregrine Falcon”, published in 1980, is a superb and comprehensive example of a monograph on a particular species. But there is no mention in it of such a wide age difference between peregrine youngsters, so I wonder how common this phenomenon might be and how it happened. This snapshot in the life of a peregrine family was absolutely fascinating. It might seem that the adult behaviour was cruel. But it is typical bird of prey behaviour designed to encourage the youngster to leave the nest if it wants food. The little thing was desperate to go but this most momentous event in its short life was yet to come.

NB. I haven’t added images of the nestlings individually or together (showing the age difference) as they would be too small. However if anyone would like to see them, just let me know.
