Royston Wildlife Blog: UK Wildlife Sightings, July 2025

I was away from Royston on three separate holidays from late June until mid July. The first holiday was a 'Naturetrek' holiday to North Macedonia, which I will write about in a separate blog post, when I have finally finished editing and sorting out over 200 images. I would have done this sooner, if I hadn't been on two further, shorter holidays to Wales and then Stockholm in July. From a wildlife point of view these were very low key - I'll deal with them briefly here.

Wales

My partner and I visited Aberystwyth in early July, as part of a family holiday (we met up with my brother and his family). Rock Pipits was seen around the castle ruins and I also saw Dipper and Red-breasted Merganser nearby. Aberystwyth is well known for its winter Starling murmurations around the pier, but of course we were six months too early (or late) to see these.

Stockholm

For my 70th birthday my lovely partner booked a surprise four night holiday for us in Stockholm (I knew I was flying somewhere, but not to where). This beautiful Swedish city, situated on an island archipelago, held a few minor surprises. For one thing, the gulls threatening to steal your fish and chips were not Herring Gulls, but Common Gulls! Lesser Black-backed Gulls would then steal from the Common Gulls. A few Herring Gulls and Black-headed Gulls were present, but these kept themselves to themselves. The only (feral) geese that I saw were Barnacle Geese (and lots of them). Other sightings included Common Terns and a single Common Redstart. Stockholm, and Sweden in general, is very expensive (not that it bothered me, because my partner was paying for everything!), but if you can afford it and don't mind missing out on the excitement of bird watching for a few days, it comes highly recommended. Most Swedes speak good English, too. Don't fly British Airways, though - they cancelled our return flight....

Back to the wildlife, and on my birthday itself we used public transport to Hammersmith and walked along the Thames to spend an afternoon at WWT Barnes, encountering a variety of hoverflies and a Jersey Tiger Moth on the way.

The reserve itself was pretty quiet - most of the wildfowl collection were moulting - but I did add three Odonata (Small Red-eyed Damselfly, Willow Emerald Damselfly and, best of all, Lesser Emperor Dragonfly) to my year list. At least two Lesser Emperors were buzzing around the many pools, but sadly they never settled for me to take their photograph, so you will have to make do with the other two. Lesser Emperors are slowly establishing themselves in Southern England (climate change?), and can be distinguished in flight from the Emperor Dragonfly by their slightly smaller size, duller colouring and a pale band around the abdomen, close to the Thorax.

On my return from Stockholm, my next significant sortie was to Aston Rowant on the 23rd, with my target being the rare Silver Spotted Skipper butterfly. On a very dull day the reserve was very quiet, with few butterflies on the wing, but I did manage to find at least one Silver-spotted Skipper (image below).

On the 25th I treated myself to a day out in Norfolk, my first visit to the county for some time. My first stop was at WWT Welney. The Wood Sandpiper, reported the previous day, had gone but I did enjoy watching a Common Tern trying to feed a fish to its chicks, which totally ignored it although a nearby Ruff took an interest. I added Brown Hawker to my 2025 dragonfly list here. I travelled on to Dersingham Bog, which was predictably rather short of water, but I did see a single male Black Darter and a single male Keeled Skimmer here. Better still, after having failed to see any here for quite a few years, I also had a couple of sightings of Grayling butterflies in flight. Once disturbed, these butterflies head rapidly for the nearest tree and hide on the trunk, where they are very hard to find.

Encouraged by these sightings, I headed on to Snettisham, which proved to be my final stop. I hoped to see Turtle Doves here, but had no joy searching for an hour in the Coastal Park, where I have seen them many times before. With the tide coming in, I decided to head south along the muddy beach towards the RSPB reserve. Ringed Plovers were much in evidence and, as I approached the reserve, some impressive wader murmurations were seen. A huge flock of (mainly) Sandwich Terns was resting on the beach, close enough to pick out individuals with my binoculars and camera, but not close enough to be certain about identifying some of the smaller terns that were sitting alongside the hundreds of Sandwich Terns. Quite a few Common Terns were present, as were one or two Little Terns. I'm pretty sure that a handful of Arctic Terns were present too, based on bill size, colour and shape, but I could not convince myself to put them on my year list.

As the tide came in further, things got even more interesting as hundreds of waders flew in closer and closer. These turned out to be mainly Dunlin and Sanderling (are Sanderling, like Knot, on The Wash all year round?). A single Curlew Sandpiper was amongst them: these birds were heading for the southernmost lake on the RSPB reserve, where a White-rumped Sandpiper and a Pectoral Sandpiper had been reported on the day (and, indeed, for the remainder of the month). On a hot day, I didn't have the energy to go further but a couple of surprises awaited me as I turned to go back. Firstly, I heard the unmistakable purring of a Turtle Dove, which eventually revealed itself after much searching. Then, I noticed a family of warblers moving about in a line of bushes and sometimes coming out on to the ground to feed - a family of Lesser Whitethroats! I've never had such good views of this species before - the birds looked quite tame. Of course I took some photos: I may never have such a good opportunity again. To complete the day, several Wall butterflies were flying about in the same area. This double brooded butterfly became extinct in Hertfordshire many years ago, and Snettisham is probably one of the closest places to home where they can still be reliably seen. What a day!
