On the top right of Anglesey is a lovely little reserve, Cemlyn Bay. It's not a big reserve, especially by RSPB standards, being one inland freshwater pool set back from a shingle bank. Run by the local Wildlife trist it is a hotspot though for nesting terns, with sandwich, common and arctic terns all nesting on the islands. It also attracts the rarer roseate tern, which occasionally nests here but mainly visits from its nesting grounds on offshore islands.
We visited twice on our holiday to Anglesey, the fist time with it blowing a right hoolie and the second a much calmer day. Judith spent the time painting the wild flowers whilst I camped out with my 'scope and camera trying to find the roseate tern! It was helped enormously by the very informative and friendly wardens who greet visitors and show them the birds.
As you can see, the islands are mainly artificial, covered in the middle with low vegetation in which the terns nest. The viewing is very good, you are partially sheltered behind the shingle bank and are at a large enough distance that there is no disturbance to the birds.
As you stand watching them, there is a constant stream of mainly sandwich terns bringing food in to their youngsters. These were parked on what passes for a beach which was a hive of activity. One thing you cannot convey in a blog is the noise, and smell, of a seabird colony. Constant activity and always something to look at!
The fishing must be good offshore as they were bringing back very good sized prey items for their youngsters. Looking out to sea you could see the decommissioned nuclear reactor, as per Dungeness and Minsmere where the warm water brings in fish.
The birds were passing overhead as they came in to the islands, so close it could make tracking them hard, but another was always on its in!
The only disturbance to the colony came not from people but a pair of peregrine falcons which had taken up residence nearby. On the first day I was there one would come bombing across the colony every 20 minutes or so hoping to catch a bird. It seemed to be fairly successful. The first sign of it coming in was all the birds rising off the islands to try and confuse it.
If you were quick you could see the peregrine diving into them before it gets lost on the melee of whirling birds.
Finally, I did manage to find the rare roseate tern. It was tricky to get onto, spending a lot of time on a sandbar off the beach.
Eventually it did come onto the beach area where you could see it a bit better. Smaller than the other terns with an all-dark, slightly down-turned bill and red-legs. It was also quite aggressive to the other birds around it! Fortunately between myself and the local volunteer we got quite a few other visitors and birder onto it before it flew back out into the bay.
It was the sandwich terns which were the stars though, feeding their ever-growing progeny.
