After a quiet few weeks of mild and sometimes wet and windy weather the daily searching has paid off! A visit yesterday evening, saw me scanning the huge flocks of Skylarks mixed with Meadow Pipits and large flocks of Linnets. I was almost done but as I scanned yet another group of Skylarks another smaller, more rusty-coloured bird was also moving along with them, very much in their slow, low-to-the-ground style, but clearly not them. On the first good view as the bird appeared from behind the furrows of soil I knew I had a LAPLAND BUNTING! The usual panic then ensued as I tried to fit my scope-phone adaptor to my scope, relocate the bird and start videoing! All of this I did but, need I say typically, as I pressed record everything flew off. I have a short clip of video with blurred soil and some fuzzy flying birds! I'd like to say the header photo is of the bird but it is one I took in Cornwall last year of a far more obliging bird. I watched the sub-flock of around 30 Skylarks fly across the track and away - at one point I thought I could hear a call reminiscent of a Lapland Bunting but wasn't sure. Either way, it disappeared and a 5-hour search this morning from first light was unsuccessful. I shall continue to search, as I'm sure others will as, if accepted by the rarities panel, this will be a first for Hertfordshire (rather surprisingly). An inland Lapland Bunting on the deck is a rare thing so re-locating it would be a very popular outcome. Searching for the bunting did reveal a few other birds including at least 2 Corn Buntings with the flock of Skylarks, 6 Grey Partridge and 4 Crossbills. Two males and a female of the latter species perched up in the tree by the ruin giving excellent views before flying over to the puddles on the track to drink. They were only there briefly before they headed towards Symondshyde Great Wood where there is no doubt a resident flock this autumn . A rare sight at Stanborough GPs - perched Crossbills! In other news, the site has been fairly quiet but highlights included a male Brambling with the finch flock along the track on 16th-18th October. Two Crossbills circled the site on 26th Oct and the juvenile Merlin was seen again in flight. A drop in temperatures (albeit short-lived) on 23rd Oct saw 6 Green Sandpipers roost and Teal numbers increased to over 40 birds. The Teal were also joined by an immature male Wigeon on various dates along with a few Shoveler. Work at the site continues apace with land drainage completed in many sections and the worked areas quickly tilled and seeded by the farmers. Attention has now turned to the main pit which is sadly being drained and exactly how much of that will be left remains to be seen. 'Enjoying it while it lasts' is the order of the day and the site is still playing host to a great variety of birds as the ground continues to be worked.

Spring fades out...The month of June finished quietly as expected with much of the focus on resident breeding birds. The first Little Ringed Plover chicks (just 2) appeared on 17th from a nest that appeared initially to have been abandoned. However, not so, and the heatwave may have accounted for the parent birds spending more time than usual off the eggs. The Little Ringed Plover eggs that became 2 new chicks! To date, just one chick survives but another nest nearby will hopefully fledge soon. The parent birds are remarkably tenacious with the the fledged chicks' nest just metres away from quarry traffic digger tracks and the second nest on a beach frequently disturbed by bored youths and other visitors. The latter part of June also saw a fair few Yellow Wagtail juveniles appear with at least 3 broods noted if not several more. Another potential breeder - Corn Buntings - have also remained on site with at least 2 if not 3 birds favouring the middle pool area. Up to 5 Green Sandpipers remained on site joined by a Common Sandpiper on 17th that was seen again on 27th & 29th. The only other birds of note were 2 adult Grey Partridge seen on 14th and a lone Teal (an eclipse male) on 27th signalling the seasonal shift and joined by another on 30th. Green Sandpiper, Corn Bunting & Common Sandpiper Autumn fades in...July opened with a sense of autumn passage with a high count of at least 16 Little Ringed Plovers on site including 3 full-grown juveniles. Undoubtedly part of a post-breeding dispersal with numbers returning to the usual 5-6 birds over the next few days. Green Sandpiper numbers have stayed at up to 5 birds but it is hoped that among them might be a Wood Sandpiper soon! A Hobby was seen on 4th along with the site's first Red-veined Darters (2) noted by visiting County Recorder for odonata species, Roy Woodward. Red-veined Darters The real highlight, however, came on 6th July with a flock of 10 CROSSBILLS headed west over the site - a new bird for the site (#159) having failed to record them during the last influx in 2020. The Crossbills were located the next day in nearby Symondshyde Wood with the flock growing to over 20 birds. The Crossbills in Symondshyde Wood on 7th July Along with the arrival of the Crossbills other birds seemed to be on the move too with 2 juvenile Stonechats appearing at the site. Their appearance is in line with previous years and are likely to represent dispersing juveniles rather than locally bred birds. A good passage of over 100 Swifts and 50 Swallows east was also noted and the Linnet flock increased from about 30 birds to well over 100.
The stage is set for Autumn passage so let's hope it's more exciting than the rather quiet Spring we've had! Late May highlightsMay did not finish with a bang but nevertheless did hold some interest with a Cuckoo heard calling on 21st along with the arrival of 2 Common Sandpipers. In line with annual movement of 'suspect' geese a very smart (unringed) Bar-headed Goose appeared on the same day along with a bona-fide ringed Oystercatcher. Originating in central Asia and migrating across the Himalayas at extreme altitudes, it seems inconceivable that a wild Bar-headed Goose should ever make it to the UK. This bird may simply be an escapee from a private collection or perhaps, a partially wild bird living as part of a feral population in the UK. Regardless of its origins it was a very smart bird and first record for the site. It follows the similar Snow Goose record of 2024. The Oystercatcher sported a bright blue & yellow leg ring with white letters HE on it. I was then able to identify this as a bird ringed by the Devon & Cornwall Wader Ringing Group on 13th Oct 2021 at Dawlish Warren on the Exe Estuary in Devon. My sighting constitutes the only sighting away from that site and the first since Feb 2023. It's interesting to see how far this bird has travelled and with some birds being re-sighted in Europe, who knows where it will go next? The full history of the bird can be found here: https://www.dcwrg.org.uk/recoveries/oystercatcher/bird/GBT-FJ28711 The last Common Sandpiper was seen on 24th May but the next day 2 more Ringed Plovers appeared and another Oystercatcher on 31st May. Another Ringed Plover was also present on 28th May. On 27th May a new brood of Mandarin Ducks appeared - a mother with 10 new ducklings in tow. Lapwing chicks were first seen on 21st with at least 3 Lapwing broods proved by the end of the month. A Lesser Whitethroat was heard singing on the last day of May and a pair of Egyptian Geese were noted - one of 3 pairs that have frequented the site this Spring. Early June highlightsThe first few weeks of June saw a trickle of waders with more Ringed Plover (2 on 4th & 1 on 10th), 2 more Oystercatchers on 6th and a Dunlin on 2nd. At least 3 pairs of Little Ringed Plovers continue to display around the site but as yet there has been no evidence of breeding. Disturbance at critical moments may have not helped the Little Ringed Plovers this year with an unwelcome visit from a walker with 4 off-lead dogs and untimely ploughing by the farmer. There is enough space on site so hopefully pairs will breed successfully in due course. On cue with previous years, a Corn Bunting was singing on the wires along the track on 11th and then seen singing at the back of the main weedy area on 13th. Hopefully a mate will be found and breeding will get underway again. Both Mandarin Ducks and Lapwing have continued to be successful with a third brood of Mandarin ducklings appearing on 11th June and a fourth brood of 2 further Lapwing chicks the next day. Of course, as June progresses, thoughts of autumn migration begin to creep in! June is a turning point in the migration calendar and first back are the Green Sandpipers. Almost before we began to expect them, 5 Green Sandpipers arrived on 13th - a very typical date for their return. At least one bird was colour-ringed and studies have shown that they can make the journey from Scandinavia in one non-stop flight! A Hobby was also hunting over the pits on 13th and 2 Grey Partridges were flushed near the ruin. One of the partridges looked very small and could have been a juvenile. A Meadow Pipit was feeding along the new tree planting area which renewed hopes that there might still be a breeding pair on site - although this was the first bird seen since the dog disturbance. Elsewhere around the site insect life has exploded with a good variety of odonata including recently Emperor Dragonflies, Four-spotted Chasers and Black-tailed Skimmers. The first Marbled White butterfly was noted on 13th along with another Painted Lady butterly. Black-tailed Skimmer & Painted Lady butterfly on 13th June
The first couple of weeks of April are almost done and I'd like to report some amazing sightings but somehow this usually peak period has drifted by quietly. A settled area of high pressure has brought beautifully clear days with a, at times, strong and chilly east wind. Rain and cloud cover have been non-existent and it feels as if these missing ingredients have resulted in a lack of migrant birds. Either birds are backing up waiting to arrive or are flying over, high in the clear skies, not needing to make the usual pitstops. That said, a steady trickle of migrants has kept things interesting if not exciting. Full of promise and headlining the period was a stunning male Blue-headed (Yellow) Wagtail of the European race flava. Found at the pits on 27th March the bird hung around for a couple of days giving many people the chance to view and photograph it. A perfect picture of Spring the bird suggested the start of something special but actually heralded a quiet few weeks! Blue-headed Wagtail Motacilla flava flava on 27th & 28th March 2025 While it feels the main influx of Spring migrants has yet to come, prior to the wagtail's arrival, there had been some movement with some expected arrivals in the from of Sand Martins and Swallows on 21st Mar. A Wheatear was found at nearby Nashe's Farm on the same day but it wasn't until 24th that one appeared in the big field at Stanborough GPs. A further 3 birds were then seen on 5th & 6th April. A slow passage for this species, especially given the seemingly ideal habitat at the pits. An Oystercatcher also put in an appearance on 21st along with another Mediterranean Gull and a Little Egret. The evening finished with a distant circling Marsh Harrier. Migrants on 21st March 2025 - Oystercatcher, Little Egret & Mediterranean Gull Two Dunlin were present on 22nd along with a singing Firecrest while a lone Golden Plover was seen flying around on 23rd & 24th Mar and then a flock of around 50 seen flying over on 27th. A single bird then appeared again on 5th April in the large field. Equally brief in its visits was a single Shelduck seen on 26th & 30th Mar then on 2nd and 5th April. Also present in the large field on 23rd Mar were a flock of around 130 Fieldfare but these had dwindled to just a handful in the first week of April. 2 Dunlin on 22nd Mar & the lone Golden Plover on 5th April A Willow Warbler was heard singing at the entrance on 30th Mar and various reports of a Water Pipit on 31st Mar and Rock Pipit on other dates were unconfirmed. Yellow Wagtails of the usual British race flavissima arrived on 2nd April with at least 10 present on 7th. Two Barnacle Geese were at the site on 4th April along with a Redshank and first singing Corn Bunting of the year. With so much of the vegetation gone it remains to be seen whether this species will breed at the site this year. Two Yellow-legged Gulls also passed through on 3rd April. Good numbers of Little Ringed Plovers remain on site with at least 16 counted on 7th April. At least 3 House Martins appeared in the hirundine flock on 6th April while the long-staying 7 Pintail dwindled to just 2 pairs and were not seen after that date. Remaining onsite were fluctuating numbers of White Wagtails, a pair of Egyptian Geese, at least 2 Green Sandpipers and up to 3 Common Snipe. Another welcome arrval was a Common Whitethroat on 10th April. Yellow Wagtails, a White Wagtail & Common Whitethroat With many of the expected migrants now arriving (the site year list stands at 105 species) the stage is set (hopefully) for something a little more special. Rain in the forecast still seems to evaporate before arriving and the skies are set to be clear for the foreseeable future so who knows?!
Despite the restoration of much of the site 2024 proved to be another very good year for birds at Stanborough Gravel Pits with 131 species recorded, just one shy of the total for the previous year. In all, 5 new species were added to the site list taking the all-time total to 156*. First to be added were the 9 Brent Geese that appeared at the site on 11th March and later in the day a Lesser Spotted Woodpecker was seen by one lucky observer - another new record for the site. The day proved exceptionally good and can be read about here. April saw the addition of a Sandwich Tern - seen by just a few observers - and then a Spoonbill in July seen by just one observer. The final, and somewhat expected, addition came in December with the arrival of a 3rd winter Caspian Gull that then stayed to almost the year end. In addition a number of escapes provided added interest in the form of a White Stork ringed at the Knepp Estate in Sussex. On 16th May a pale-morph Lesser Snow Goose joined the goose flock and tempted thoughts that it might possibly be genuinely wild. However, without a ring to prove it one way or the other, it is most likely a roving bird from a feral flock elsewhere. The White Stork (photo from off-site) & the Snow Goose Aside from the new additions, 2024 also held some real highlights on the wader front with the freshly scraped areas clearly proving attractive to migrant waders. The 3rd May saw the site's second Avocet, 3-4 Little Stints on 21st & 22nd May, and both Spring and Autumn Wood Sandpipers. Bar-tailed and Black-tailed Godwit, Curlew, Grey Plover and Sanderling also put in a good showing with a very smart summer plumaged Grey Plover from 15th-16th May. Other highlights in 2024 included more records of Pintail than in previous years and many more records of Marsh Harriers with up to 3 different individuals visiting the site throughout the year. The presence of these birds begs the question as to whether they will attempt to breed in the near future - either at the site or in the St Albans area. An Osprey on 5th April was the only record for the year while up to 4 Scandinavian Rock Pipits were on site from 11th-13th March. A Black Redstart on 9th November was a welcome late autumn visitor too. Osprey & Black Redstart While no evidence was found of breeding Lapwing this year, Little Ringed Plovers did breed successfully with at least 3 pairs raising a brood. The site continues to be the main breeding site in Herts for this rare British breeding bird. Little Ringed Plover numbers peaked at 17 on 23rd June and the last birds seen on site were on 15th August. A lingering pair of Ringed Plovers gave hope that this former Herts breeding species might consider staying but they eventually left by the second week in June. Other notable breeders at the site included Mandarin Ducks (although numbers were down on the previous year) and both Little and Barn Owls. Sand Martins are likely to have bred but in small numbers while a pair of Corn Bunting may also have bred. A number of birds recorded in 2023 were not seen in 2024 - some less surprisingly than others. Garganey, Whimbrel and Ruff were surprise absences while Bewick's Swan and Turnstone less so. The removal of the large scrubby area as part of the gravel pits restoration work meant that Sedge, Reed and Grasshopper Warbler were not recorded on site - a real loss as at least 2 of those species bred in 2023. Common misses included Bullfinch, Brambling and Garden Warbler while Water Pipit and Tree Sparrow absences were less surprising. Looking ahead to 2025...So what will 2025 hold? The site restoration work is scheduled to continue in the Spring and it is unclear how the site will eventually look. It is hoped that bodies of water will remain with attractive margins for birds. As to the longer term management of the site, that is unclear. Without any management successional growth would stifle the site and remove the scraped areas attractive to birds such as waders, not least the breeding Little Ringed Plovers. Disturbance is also a concern, not just from quarry work but also from increased shooting by the local farmer. The sighting of a fleeing fox before a fox-hunting group with horses and hounds was also a worrying development. Only time will tell but the site remains a fantastic opportunity to create a nature reserve should the landowner and land-managers be so minded. It also functions as an important flood-management system, storing water that would otherwise put pressure on the river and drainage system. The site awaits a vision and hopefully, when there is one, it will recognise the high-value of the site for birds and wider nature. Bird-wise, hopefully 2025 will deliver the same excitement of the last few years. Some notable holes in the site list exist such as Curlew Sandpiper, Spotted Redshank, Common Redstart, Pied Flycatcher, Hawfinch and Crossbill among others. Will 2025 see these added? We shall have to wait and see...! *Attentive readers will note that this is one down on the previous published total as Ruddy Shelduck was removed from the list as a species not yet accepted on to the official Herts List. The status of Ruddy Shelduck in the UK is currently under review by the BOU (British Ornithologists Union) but the outcome of that review is still pending. Instead, the species must be relegated to the "Escapes & Introductions" category as a non-wild bird.
June is a busy month at the pits for breeding birds with many farmland birds finding the site attractive. This year an oil-seed rape crop has been buzzing with life supporting not just many insects but breeding pairs of Reed Bunting, Whitethroat and Skylarks. The field has also attracted surprisingly large flocks (for this time year) of Yellowhammer (20+) and Linnet (60+). The month as also seen a couple of Hobby visiting the site, at least 2 Corn Buntings singing from the weedy field margins and several pairs of Yellow Wagtails raising young. Pied Wagtails seem to have had a particularly good season with juvenile birds almost everywhere you look! At least 4 pairs of Little Ringed Plover have successfully hatched young although it is not clear how many went on to fledge. A pair of Ringed Plover, once a Herts breeding species, lingered to the middle of the month giving hope that they might breed but the last bird departed on 16th. Mandarin Duck numbers have fluctuated but a female emerged with 11 ducklings on 16th. Compared to last year, at least to date, the Mandarins don't seem to be having such as fruitful year and this may have something to do with increased disturbance on site and the removal of areas they would formerly have used. Both Little Owls and Barn Owls have nests on site and the Barn Owls have raised at least one chick and probably more. In addition, a Cuckoo seen on 28th gives hope that they may too have bred nearby. At least 3 singing males were present in the Spring and may well have bred around the Symondshyde Farm end of the site.
Some species appear not have faired so well this season such as Lapwing that, despite being present on site most days, don't seem to have taken advantage of the seemingly perfect habitat. Sand Martins also seemed to adopt a number of holes from last year but haven't raised young from them. That said, they remain in good numbers on site so may have bred nearby. |
