After a changeable first week, in which there was some (but not enough) rain, the weather settled into another spell of very warm or hot weather, with the fourth 'heatwave' of the year arriving from the 11th - at least in the Royston area. On Therfield Heath, Chalkhill Blue numbers peaked at the beginning of the month, before a gradual (or rapid, in the case of Gatekeepers) decline of these and most other species set in. The exceptions were Small Heath, with the appearance of another generation, and Adonis Blues, first reported at the end of July, which were present at both ends of The Heath by the 9th. There was a welcome increase in numbers of these in the second week of August, with a few males being seen away from the colonies on the Old Rifle Range and Church Hill. There has been a small influx of Clouded Yellows from Europe this month. Some were reported on The Heath on the 10th and a single butterfly flew north past me, on the Old Rifle Range, on the 11th.

Local Wildlife Sightings, August 2025
UK Wildlife Sightings, August 2025
Whilst my previous visit to East Anglia, in July (to Welney, Dersingham Bog and Snettisham), had been full of interest, birds, new dragonflies and butterflies, my next visit, to Walberswick on the 6th, was quite the opposite. Mind you, I had a single target in mind - Britain's 10th (I think) Zitting Cisticola (aka Fan-tailed Warbler). The bird had been present for some time when I visited, and there were only a handful of people waiting for it to appear. I sat down to wait, looking inland towards a marshy area with a river channel running across about 200M ahead, for possibly the most boring three hours of my life. I heard the occasional 'zit' and, after a couple of hours, I saw the bird distantly in 'song flight' (I couldn't hear the song when others could, perhaps my hearing is not as good as I thought). Eventually, I did get a better view of the song flight and was able to properly 'tick' it off (my 371st UK bird species). What made the wait so boring was that there were hardly any other birds to see, at least until the last half hour (early evening), when the occasional egret flew by. The Cisticola is still present as I write on the 15th, so at least all UK bird watchers will have had the opportunity to see it.
July and August are 'dragonfly months' for me, when most of our UK species are on the wing at one time or another. I made a couple of trips in the first half of the month, looking to photograph particular species. First off was a visit to Santon Downham (Suffolk) on the 8th, my second of the summer, to have a go at photographing Banded Demoiselles. There were far fewer to see than on my first visit (see my June UK blog), but the ones that were present were somewhat easier to photograph, because they weren't being constantly disturbed by the flights of their neighbours! Good numbers of Ruddy Darters and Willow Emerald damselflies were also present along the banks of the river.
I also made my annual visit to Paxton Pits (Cambridgeshire) to photograph the Common Darters there, in an area where there are usually 50+ on the wing at this time of the year. I came away with nearly 100 images, which were reduced to a dozen after editing. Here are a couple that I like.
On the 13th I chose my first visit of the year to Thursley Common in Surrey for a day out. It turned out to be a bad choice: the M25 western section was a nightmare in both directions, the road that I access to park at the Moat Pond was closed for roadworks, necessitating a 15 mile diversion and then there was a thunderstorm not long after I had arrived, cutting short my visit. Target dragonflies were Small Red Damselfly (which I did see) and Brilliant Emerald (which I didn't). Several Black Darters and Keeled Skimmers were also encountered before the rains came, as were some Stonechats close to the Moat Pond.

"Butterflies and Birds of North Macedonia" - 'Naturetrek' Trip, June - July 2025
Every year I take a wildlife holiday to somewhere in the world that I have not previously visited. In 2023 it was Japan, in 2024 it was The Gambia and this year I chose a shorter holiday, closer to home, in North Macedonia (formerly part of Yugoslavia). Two of my major wildlife interests (bird watching and butterfly photography) were well catered for and there was the chance to see other wildlife (particularly invertebrates and reptiles) that are not encountered in the UK and Western Europe. Unfortunately, the original leaders had to pull out due to illness. They were replaced at short notice by Slave, who proved to be an excellent and knowledgeable bird guide and leader, and Marek, the butterfly expert, who came all the way from the Czech Republic and proved to be a very keen and enthusiastic leader on all things 'butterfly'. Our group of 14 clients contained a considerable amount of expertise and I found that, as in The Gambia, that whilst at home I may be considered the 'local expert', here I was of little help in species identification. The party included some very keen 'moth-ers', who brought their moth traps with them and were up at 4.00am to check what the traps had captured.
North Macedonia is a small and beautiful country of mountains and plains. It is also very hot, with temperatures above 30C being 'the norm' for the time of our visit. In fact, temperatures reached 40C on our first two days, when most of our wildlife watching was done early or late, before returning to normal (around 30 - 35C) for the rest of the trip. The food was good and plentiful (perhaps too plentiful at times, as we were treated to some large lunches in cafes and restaurants). The first hotel (three nights) was good, although the air conditioning in the second hotel (four nights) left a lot to be desired and led to some poor sleeps. Only 'Wizz Air' departures from Luton fly directly to and from Skopje (the capital of North Macedonia) and they depart late in the evening, meaning that our arrival at the first hotel (12.30am) and our arrival back at Luton (2.00am) led to sleep deprivation (a common factor, it seems, on my wildlife holidays). I'll deal with the wildlife in three sections, Birds, Butterflies and Everything Else.
