Local Wildlife Sightings June 2025

 After an impressively warm and sunny spring, it was back to changeable weather in June with a few warm, sunny days interspersed with showers and longer periods of rain. I took the opportunity on the 2nd (a warm, sunny day) to visit local fields and Therfield Heath, looking mainly for butterflies. Numbers of first generation Common Blues and Brown Argus butterflies were falling now on The Heath, whilst I failed to find any Adonis Blues there. However, on the small wild flower patch in the field that is behind our estate, which has proved quite productive in the past, I was lucky to find a recently emerged male Common Blue, which flew conveniently towards me and perched on top of a flower bud, allowing me to take some nice photos. If only all insects were so obliging!

 On the 2nd I made my annual pilgrimage to Glapthorn Cow Pasture NR (near Oundle in Northamptonshire) to see Black Hairstreak butterflies. Impressive numbers were on the wing, indicating that this species, at least, has not been adversely affected by the poor weather in 2024. I also saw my first Large Skipper of the year here.

On the 4th I returned to Bempton Cliffs to spend time with my brother and his family, who were holidaying in the area, and introduce them to the wonders of this RSPB reserve. My brother is a keen and very good photographer, but rarely photographs wildlife. However, whilst we were there he took 900 (admittedly, bracketed) images whilst I took very few! Here are a couple of my images.

Local Wildlife Sightings May 2025

 The hot weather continued into the start of May, with temperatures reaching around 27C, before declining dramatically as north-easterly winds set in from the 3rd. By the 4th the temperature in mid-afternoon was just 13C with a significant wind chill factor making it feel even colder, and I had gone from a light polo shirt to three layers, with a fleecy jacket on top. Whilst the weather was still hot on the 2nd I visited Church Hill and was encouraged to see at least ten (presumably) male Brown Argus butterflies flying over the low-cut grassy slopes, after this species did so badly in 2024. The cutting of the grass here in late summer last year should benefit this and other 'blue' species. Also seen were two Small Heath butterflies and small numbers of Peacock, Brimstone, Red Admiral, Comma, Orange Tip and Green-veined White butterflies.

The warm weather soon returned, with prolonged sunshine during the middle of the month. Back on Church Hill on the 7th I couldn't find any Brown Argus butterflies (they only live in the adult stage for a few days), although a single Common Blue butterfly was seen at the bottom of the hill, a very early Broad-bodied Chaser dragonfly was seen nearby and a Mother Shipton moth (also seen on the 2nd) was photographed. This attractive, day-flying moth has a beaky 'face' marking on each wing, presumably giving it its name: see if you can make it out on the image (below). I was pleased to see that two male Spotted Flycatchers were 'singing' (a few high-pitched, squeaky notes) in Fox Covert on either side of the Therfield Road. This is a very early return for a species that can turn up as late as the beginning of June, but there had already been several reports of this species before 'my' birds were seen.

Ox-eye Daisies, generally a flower of early June, were already flowering when I walked up onto The Heath on the 13th. I noticed that a fly was apparently sitting on one flower head. Closer inspection revealed that it had been captured by a predatory Crab Spider (stealth killers - they don't make webs), which was smaller than the fly (image below). On The Heath, three male Adonis Blues were flying on the Old Rifle Range, and looked to have been on the wing for at least a couple of days. This is fairly early for Adonis Blues, and was no doubt due to the fine, sunny weather in April and May.

In 2023 and 2024, Chalkhill Blue butterflies did not emerge on Church Hill, although a few were seen flying there in the late summer of 2024. After only a few Adonis Blues were seen here in the spring of last year, and no second generation was seen, I assumed that the latter species had been lost to the poor weather at this site. However, when I checked the south side of Church Hill on a sunny afternoon on the 16th I was surprised to see several male Adonis Blues and a single female flying. As previously mentioned, Church Hill had been mown in the late summer of 2024 and was now covered in Horseshoe Vetch. Was there an unnoticed, very small second generation of Adonis Blues in 2024, or could the adults possibly have started life as eggs laid by last year's first generation? Another possibility is that they were re-introduced by whoever originally introduced them to The Heath. I guess that I'll never know. Present with the Adonis Blues were several Common Blues (all males) and Brown Argus butterflies, whilst in Fox Covert another Broad-bodied Chaser dragonfly was seen. A similar mixture of butterfly species was seen when I returned to Church Hill on the 21st, with slightly fewer Adonis Blues and Brown Argus, but even more male Common Blues.

Other sites visited in Hertfordshire during May included Wilstone Reservoir (Shelduck, Hobby, Swift, Common Sandpiper, Dunlin and Little Ringed Plover seen on the 8th) and Amwell, where I saw my first Red-eyed Damselflies and Banded Demoiselles of the year on the 12th.

The weather became more changeable towards the end of the month, although still with some warm, sunny days. Another visit to Amwell on the 23rd provided me with sightings of Cuckoo, Cetti's Warbler and a very early Green-eyed (Norfolk) Hawker dragonfly. A Great Crested Grebe caught and ate a large Crayfish whilst I was watching (image). The 26th saw me at Hillbrow (Letchworth), looking for Small Blue butterflies. I did eventually find half a dozen on a very windy day, but there was little else to see until a male Orange Tip butterfly fluttered by and conveniently stopped for me to photograph it.

A large flock of Ringed Plovers (12-15 individuals) arrived at Wilstone Reservoir in late May, staying for a few days. These birds, which looked slightly different to the birds that I see on the Norfolk coast, were likely passage migrants, heading to breeding sites in Northern Europe. I went to see them on the 28th. A Little Ringed Plover (resident?) and two Dunlins were also seen. Whilst I was in the area I took a walk along the Grand Union Canal from Wilstone village. A single, female White-legged Damselfly was seen on the bank of the canal, and I also had a bit of fun trying to photograph the very mobile Banded Demoiselle dragonflies on another windy day.

Locally, I found what I believe is an 'instar' Speckled Bush Cricket (only about 5mm long) on a walk along the Icknield Way east of Royston on the 27th and three Bee Orchids in a hollow on Church Hill on the 29th. When I came back with my macro lens to photograph the most impressive of the orchids on the 31st I was lucky to see a very early Marbled White butterfly, the first to be reported in the Herts. and Middlesex region and the first that I have ever seen in May. No Adonis Blues were seen on either visit, although they were reported by others visiting The Heath at the end of May and early June.

In the garden, recently fledged birds started to appear towards the end of the month including, surprisingly, juvenile Greenfinches. Blue Tits, Great Tits and Blackbirds also brought their young into the garden, whilst frenetic Starling activity and noise suggested that their young would soon be fledging.

 Temperatures in London reached 28C on the 1st, when my partner and I visited Chelsea Physic Garden. The two small ponds there hosted a Four-spotted Chaser dragonfly and Large Red and Azure Damselflies, the first Odonata that I have seen this year.

News of a Spotted Sandpiper (the American equivalent of our Common Sandpiper and a rare visitor to the UK) on the dam at Grafham Water encouraged me to visit on the 2nd. This very spotty specimen (see image) showed well on the dam. Nearby, a female Wheatear and a Little Ringed Plover also showed well, although I missed seeing the reported Whinchat.

On a much cooler day on the 5th I made my first visit of the year to RSPB Frampton Marsh, in Lincolnshire. My key target was Temminck's Stint, a wader that migrates northwards through the UK in very small numbers in the spring but is even scarcer on return migration in the autumn. I was lucky to see both the Temminck's Stint and a somewhat commoner Little Stint. It is hard to get close enough to these tiny waders to get decent photographs, and those of the Temminck's Stint are not worthy of inclusion here. Also seen were Common Sandpiper, around a dozen Ruffs including a male in breeding plumage, my first Swifts of the year and a lonely Whooper Swan with a badly damaged wing, which unfortunately will have to spend the summer here.

It was my turn to lead an RSPB trip to Frensham Common (Surrey) on the 18th. This area of Surrey heathland is, like the nearby Thursley Common, a haven for rare spring breeding birds (Woodlark, Redstart, Tree Pipit etc.) and invertebrates. A reconnaissance trip on the 9th produced sightings of all the expected bird species except for Woodlark. A surprising number of dragonflies were on the wing, presumably encouraged to leave the ponds early by the warm weather. These included Beautiful Demoiselle, Hairy Dragonfly and Downy Emerald (on Frensham Little Pond).

Everything went well on the 18th and additional sightings included Woodlark (which I saw), Whinchat and a juvenile Tawny Owl (which I didn't). Scarce Chaser dragonflies were added to the list of Odonata.

The continuing sunny, warm, spring weather led to me spending far too much time 'in the field' at the expense of arguably more pressing matters. On the 13th I made a trip to Whipsnade Downs, looking for butterflies that don't occur on my local patch. Lots of Duke of Burgundy, Dingy Skipper and Green Hairstreak butterflies were seen, but I could only (after a lot of searching) find one Grizzled Skipper, presumably because this species, which normally flies until late May, was reaching the end of its season early due to the continuing warm, fine weather. Lots of Brown Argus and Common Blue butterflies were also seen here.

I drove to RSPB Lakenheath Fen on the 14th, adding a rather distant male Garganey on the washland to my year list. Several Cuckoos were seen, but a strong, coolish breeze kept insects down as I made my way to the far west of the reserve (Joist Fen). On the way back through the reserve, the sun came out and, in areas sheltered from the wind, huge numbers of dragonflies and damselflies were on the wing. Four-spotted Chaser dragonflies reached almost epidemic numbers - I must have seen at least 100. Several Hairy and Scarce Chaser dragonflies were also on the wing, as were a few species of damselfly including the uncommon Variable Damselfly.

The nesting pair of Ospreys were seen at Rutland Water (Lyndon reserve), when I made a brief visit on the 15th. As work, gardening and administration piled up at home I made a final 'annual' long distance spring trip to the Peak District (Ladybower and Cutthroat Bridge) on the 20th. Despite very good, warm, weather (very unusual here in May) my walk on to Derwent Edge, although as enjoyable as always, was let down by a paucity of birds. I failed to see a single Red Grouse (had they all been shot on this grouse moor?) and, down in the Ladybower Nature Reserve, I could neither hear nor see any Pied Flycatchers, although a few Spotted Flycatchers were seen. Could the Pied Flycatchers already have finished nesting, or had they simply not returned? I saw several nest boxes, but none were occupied - very sad. I did have good views of Ring Ouzels and heard Redstarts, Cuckoos and Tree Pipits, but this was a disappointing day for bird watching.

Swallowtail butterflies were on the wing early this year (first seen on 2 May), so I made a visit to RSPB Strumpshaw Fen on the 30th, hoping to see them and also photograph damselflies and dragonflies. Unfortunately, my only Swallowtail sighting was of an individual that flew rapidly past me, giving me no chance to photograph it. Territorial male Scarce Chaser dragonflies were, however, much in evidence, as were Banded Demoiselles and several species of damselfly. Bird sightings included Kingfisher (seen from both sides of the reserve), Marsh Harrier and Cetti's Warbler. On the way back I stopped off at Icklingham, to do a reconnaissance visit for a walk that I was due to lead to Cavenham Heath in June. At least three pairs of Stonechats and two Curlews (which breed here) were seen on the heath, but I couldn't see any members of the target species, Stone Curlew.
