Soft shoe patching



Its a romantic notion, but I've always considered myself an old school field naturalist, free spirited, rooting through undergrowth and vaulting fences in an effort to see, appreciate and record wildlife. Looking for nests, potting insects for closer inspection at home, taking voucher specimens, scribbling notes with pencil and paper, filling my pockets with a boyish eclectic mix of nature paraphernalia is all part of Enid Blyton type job description. This approach was, and still is, somewhat inspired by the writings of Gilbert White but more recently by the work of a new breed of passionate nature writers such as Stephen Moss and Tim Dee who scribe so descriptively about the wildlife, landscape and the characters of local patching. My motivation, driven to some extent by the prejudice and unwillingness of moleskin trousered policy makers to recognise the value and potential of post industrial Gwent, is to raise the profile of natural heritage in my own little patch of the south Wales coalfield and maybe leave a legacy in keeping with that of the traditional naturalist's of yesteryear.

That said my days of being shouted at by a farmer for a harmless intrusion onto private land seem to be fading in the memory. I look back with a wry smile to an era when as a small group of valleys teenage birder's were told to 'get off' by bailiffs at Llandegfedd Reservoir as 'you are trespassing.' How things have turned full circle! These days the growing commitments of supporting elderly parents and grandchildren have fashioned a less adventurous itinerary, I've now adapted to a more sedentary pace. Snapshot visits as opposed to day long excursions, urban nature instead of mountain birding, comfy shoes in place of wellies or walking boots and foreign holidays instead of wild camping. It's this evolution in activity that's brought me into contact with the varied nature of the grey infrastructure and with it a fresh appreciation of its ability to colonise and soften the stark, cold angular features of the built environment, despite municipal efforts to keep it at bay.

I have no real idea if I have an audience for this blog, but if you've dipped in occasionally you will have no doubt recognised a trend for birding around the banks of the River Usk in Newport. Here gulls are the main pull for a now increasingly portly, canvas shoe urban naturalist. With easy access to the waters edge and a circuit that, depending on what's to see, takes no less than a couple of hours, this venue is ideal for a time strapped, brow beaten family man.



On Sunday 23rd July the mid afternoon tide was at its lowest as I side stepped a small thinly distributed gathering of mainly parents and young children. It seems the Riverfront Theatre had organised a package of street theatre events including a Sherlock Holmes production by the Smallest Theatre in the World. Once the volume of these new age cultural activities had faded I settled into scanning the gathered masses of gulls that had alighted waters edge. Here the falling tide revealed a muddy canvas that is a montage, a continuum of strewn rubbish from bikes to CD players, garden tools, assorted building materials, shopping trolleys and traffic cones. Nonetheless the birds were here to feed on the rich marine diversity that sits between the trappings of a throw away society.


Regular patching promotes familiarity, enabling profile building of the local bird community, from numbers of birds, to species composition and even on to individual characters. The herring gull shown in the above image has been present for a couple of weeks now, its aberrant deformed bill suggesting some mutant gull wader cross, but according to my copy of  Gulls of Europe, Asia and North America (Klaus Malling Olsen and Hans Larsson) it seems this type of deformity is frequent in first year herring gulls. Also on show is another herring gull with an awkward twisted foot. It appears to manage well with the foot cushioned by the soft mud, but must be more uncomfortable on hard surfaces.


July is a good time to see yellow-legged gull. This is the season when post breeding adults and juvenile birds drift into south Britain in moderate numbers. My birding on this patch over the last year or so has produced infrequent single birds, of mainly adults. First year birds are swines to separate from herring and lesser black-backs but with an increasing knowledge of plumage's identifying my first juvenile yellow legged gull is surely not far away. Adults tend to be easier to sort, helped by visibility of leg colour. This adult has been around for a couple of weeks. 


Another quirk of gull watching is colour ring reading. The long term colour ring study of urban gulls by Peter Rock in Bristol produces a number of records from Newport. This bird, orange A+D, is a known Bristol bird, first noted by myself earlier in the year.

Purple Hairstreak twitch



It was good to spend an hour in the company of Craig Constance and Tim Griffiths at Llandgedfedd Reservoir recently. Craig had let slip he'd recently seen purple hairstreak around the tree tops on the Island at the Reservoir, so remembering that former Gwent birder Adrian Hickman had recorded them in the same area many years ago it was worth another look. Sure enough a single butterfly came within range resting on a nearby ash trees absorbing the warmth of the early morning sun light. This individual was soon joined by a second and a possible third was seen nearby. It's not that this species is unsual, but its notable in so much that looking for butterflies is generally a low herbage activity, looking in the tree canopy isn't often neglected.

Looking out for Gulls


Gull watching is hardcore; shunned by many as just urban pests or just too difficult to get to grips with. But those who chose to embrace Laridae quickly become enveloped in a world of variable plumage, ring reading, winter roost watching and the befriending of other gull watchers through specialists blogs. However, gulls are not just for the winter birder, shivering in dropping temperatures awaiting a roost to build on a local reservoir, gulls, are all year round value with breeding interest in the spring to early summer movements from June onwards.


As I write there is already a hint that post breeding movement is underway. Black-headed gulls are turning up at some of our best sites after breeding, and yellow-legged gull, especially, non breeding sub adult birds, start to appear from late June onwards. With this in mind I took to a loop around the Riverfront, Newport at low tide hoping for something more attractive than just the local rooftop breeding herring and lesser black-backed gulls. 


Although there was a pleasing count of birds along the tide line none were significantly different enough to warrant the scrutiny needed to separate a sub adult yellow-legged from a rank and file herring. But like many who's life is scratching a living from the often unforgiving urban environment some birds display the scars of this life style choice,often manifested by foot deformities. There was an adult lesser black-backed gull with a foot amputation and a rather bleached sub adult herring with a twisted foot at a right angle to its other.  


On the roof top in Brynmawr there are currently hundreds of gulls, swollen by the young of another successful breeding season. From my observations it seems the lesser black-backs start to breed earlier than the herring gulls resulting in the youngsters showing more maturirity. Disappointingly the pair of great black-backed gull that have nested for the past two seasons at this location appear not be present this year.

Heath Bumblebee




Photographed this little beauty at Blaenserchan recently. Its a heath bumblebee (Bombus jonellus), rather attractive bee with three yellow bands and a white tail. Note the heart shaped face that distinguishes it from the garden bumblebee (Bombus hortorum) and the yellow that makes it a male. Bumblebee Conservation class this species as common yet Aderyn the Welsh Local Records Centre database only shows two records for vice county 35.

Garn Lakes Local Nature Reserve



Yes, I'm baised, but Garn Lakes Local Nature Reserve is a super wetland site, of ponds, lakes, reedbeds and marshy grassland. Credit to all those in Torfaen Council (and partners) for managing the site so well! A whistle stop visit the other evening was sufficent to record a number of odonata, the colourful hoverfly (Leucozona lucorum) and a jumbo queen buff-tailed bumblebee. Well worth a visit.

Magor Marsh



The prospect of a variable damselfly and an unsual longhorn beetle was sufficent motivation for the drive to Magor Marsh last Saturday afternoon.Nice to see some young families using the reserve and a digiscoper photographing I know not what from the hide.

Mistletoe often resides in tall trees, out of reach to a naturalist with a sweep net. But there are some more accessible clumps on the reserve that I adjatated with my net. This produced several examples of the mistletoe bug Pinalitus viscicola.



Cetti's warbler, reed warbler and reed bunting could all be heard as I weaved my way over the snaking boardwalks to the meadow beyond. Here there were many blue damselflies but none could be made into a variable. Botanically it was nice to record a few saw wort specimens along with marsh ragwort. One of the many bird boxes was home to a triving nest of tree bumblebee.

A spot of good luck


I stood in the same location of the Lasgarn Wood last year hoping to hear the churring of a nightjar but drew a blank, This time it was different but before I picked up that faint yet evocative churring I was tipped off to their presence by a knowledgeable jogger who directed me to a tree about a hundred yards away. And sure enough as I approached the said area I could hear a bird calling. To my surprised I could see the bird resting on the outer branch of a tree. After a few minutes another bird approach and both took off out of sight.

Tyr Abraham Harry



This is an area of industrial workings in the upland landscape of Garn-yr-erw, Blaenavon comprising remnant buildings and stonewalls surrounded by spoil tips and water management features. It seems that every time I tramp around this interfered with habitat I find new and interesting components. Some of the most notable are ponds that are a clearly of manmade construction given their shape.


It was a rather cool and blustery day as I made my way towards the Hills Pit area. There were a pair of wheatear in alarm call and as I scrambled through the heather covered lower slopes of a spoil tip a meadow pipit was flushed from a nest of six eggs. Beyond, there are a couple of ponds with intermittent willow scrub, here a couple of juvenile stonechat called, along with a reed bunting and a single snipe.

For how much longer?



Since the closure of Blanserchan Pit in the 1980s and the subsequent purchase of the valley by the local authority, I've witnessed a gradually change in this landscape. From a characteristic post industrial blandness to one that threatens to become woodland, sofening the Cwm in a carpet of birch and stubben conifer. The battle against scrub encroachment is now reduced to local authority guerrilla action; management when resources become available. However, without a concerted, consistent effort to reduce and restrict, the progression of succession from open vista with its blackened tips and seek and find fragments of industrail relicts will be lost, remembered only by those Facebook pages with monochrome images of the past.

Despite this ongoing change some patches of more open grassy swards can still be found. It was windy but that didn't stop a number of butterflies and moths taking flight. Around eight dingy skipper and three small purple-barred day flying moth were evident. According to the distribution maps prepared by Martin Anthoney (County Recorder), the small purple-barred has lost ground in the east of the county with just a few sites remaining in the west.

Call of the Curlew


I'd hardly got of my car when two loudly calling curlew flew overhead from east to west. Garnlydan Reservoir was strangely quiet, previous visits were populated by ubiquitous dog walkers and fishermen, not the case today. A circuit of the reservoir produced a bird list that any self respecting birder could predict. The tally included, at least four territory holding wheatear, two male stonechat, two calling reed bunting, five lapwing, and singles of common sandpiper, snipe and great crested grebe.

Twitter for Gwent bird news ( #gwentbirds )


Most of Gwent's birders, beyond the beginner stage that is, now use Twitter as the primarily source of sharing bird information, by adopting the hashtag #gwentbirds. This is where I picked up news of the ring ouzel found by Craig Constance at The British recently. Next day I was up early for a walk around my lapsed local patch hoping to find my own ring ouzel. A couple of blackbird flying along the upland fringe were double checked for that tell tale white crescent, but as hard as I try I couldn't turn any into the target species. Nonetheless plenty of other species were on offer including singles of wood warbler, greenfinch and whitethroat. There were many singing tree pipit, males of stonechat and reed bunting at lease two pair of wheatear and two cuckoo.

Remembering Abergavenny Sewage Works


I've a head of silver hair which is why I can remember those days in the 1970's when Abergavenny Sewage Works littered the pages of the Monmouthshire/Gwent Bird Report with records of yellow and white wagtail and various passage waders, In those days of course visibility of the treatment works was good, today its like Fort Knox. I recollect an anecdote often relayed by the late Percy Playford back when I was an active 'c' ringer, saying that he had previously run a number of mist netting sessions at the site during which time some of the sewage beds were characterised by large plants yielding a healthy crop of tomatoes, which he subsequently picked and took home to eat.

From Waitrose supermarket cross the road to the new housing estate on the old Coopers Filters site. Heading south and before the fly over there is a restricted lane entrance with a bright yellow barrier. Access can be found around the barrier, the lane then continues adjacent to the housing estate and straight to the sewage works. Where the housing stops there is a field with a pond, the margins supported a good population of slender ground hopper - there was also a single coot and one unaccompanied mallard duckling. A whitethroat sang from a nearby thicket. At the sewage work there is a well worn track, not thought to be a public footpath. This led through two fields to the margins of the River Usk. Here a couple of grey wagtail and a common sandpiper moved between stony spits. A few common wildflowers were in full bloom including, common fumitory, common cornsalad and green alkanet. There were also four species of butterfly on the wing, including red admiral, speckled wood, and orange tip.

We ride with impunity



The early morning Bank Holiday Monday visit to the margins of Waunafon Bog was thrilling and depressing in equal measure. Thrilling because my hope that a grasshopper warbler would be reeling was confirmed, in fact there may have been two birds. I went into stealth mode in the hope that the loudly reeling bird could be photographed in action, But despite having a grandstand view of the scrub from whence the bird was singing, as hard as I tried it was impossible to pinpoint. Moving on a male stonechat was fencepost hoping and parties of swallow were sweeping silently over the bog purposefully heading north. Other birds noted were linnet, three pair of reed bunting, two snipe and two flyover Canada goose.



And now for the depressing part - look away now those of a nervous disposition. The bog itself is a long time neglected ecological asset of SSSI quality. At the headwaters of the Afon Lwyd water appears to have been diverted away from the bog to prevent it causing a flooding problem on a nearby road. This has contributed to a perception that it is drying out in places illustrated by increased scrub growth. Nonetheless the bog, whose role in carbon storage and ecosystems resilience should not be underestimated, is facing a more immediate threat. Off - road activity has carved a deep scar in the peat and in the process breaking fences to gain access. Those responsible ride and destroy with impunity. Its incredulous that authorities seem unwilling to act to kerb the damage that is becoming a landscape trademark of the upper Afon Lwyd.

Beetle bank


I should have been more alert to the prospect that a sunny early spring Sunday at Llandegfedd Reservoir would have a liberal sprinkling of leisure seekers. And so it was, there were, walkers with dogs, walkers without dogs, cannabis smokers, sunbathing courting couples, fisherman, sailors with associated noisy powerboats and hooters, paddle boarders who sought refuge in the less crowded corners of the reservoir and an individual who coughed loudly and intermittently from the richly vegetated upper reaches of Green Pool.


As a consequence my trusty Opticron scope was not deployed. Preferring to potter about on the margins of the reservoir I settled down on the exposed shoreline of the island. The water level was high by still low enough for a small area of eroded soft bank complete with ample stone turning potential. On closer examination the collection of stones on the waters edge were well populated with a variety of basking beetles. Seemingly attracted by the stones absorbed warmth the following species were identified.

Mint Leaf Beetle (Chrysolina herbacea)

Weevil (Sitinia lineatus)

Imperial Rove Beetle (Staphylinus caesareus)

Dung Beetle (Aphodius sphaecelatus)

Flea Beetle (Longitarsus membranaceus)

Sap Beetle (Glischrochilus hortensis)

Weevil 

Orange Ladybird (Halyzia sedecimguttata)
