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.

I believe there may be a Golden Rule of patch birding - never leave your patch with the added consequence that, if you do, chances are the 'Big One' will turn up! Well, there's nothing like learning that lesson the hard way... Taking the opportunity to work remotely and catch up with some coastal autumn birding I headed down to Cornwall for a week on 28th Sep. I left as the first hints of winter birding were beginning to appear at the pits. Teal numbers had grown to 15, the odd Snipe was flying around while 5 Golden Plovers made a brief appearance on 23rd and a Wigeon was seen on 24th. The Dartford Warbler had last been seen on 25th, a Reed Warbler on 26th and a Wheatear on 30th. It seemed to be quietening down - or so I thought - but I perhaps should have taken the hint when Andrew Steele queried a wader he was struggling to ID on 25th. Neither of us could relocate it and his distant photos were inconclusive and suggested an odd-looking Green Sandpiper. It did, however, get me wondering about Pectoral Sandpiper as a possibility. That said, I don't think Andrew's bird was, HOWEVER, late in the evening on 30th another observer reported 2 Green Sandpipers and 1 probable Dunlin... Sure enough, I received a message from Steve Pearce the next morning saying he had an 'interesting wader' at the pits. His description sounded a perfect fit for a Pectoral Sandpiper so I put the suggestion out on the WhatsApp group asking if anyone else could investigate. Remarkably quickly, another local birder, John Yates, located the bird and from his photos it became clear that Stanborough was playing host to a PECTORAL SANDPIPER! The Pectoral Sandpiper from 1st - 3rd Oct - photos by Mike Illett Not only a first for the site (#162) but a genuinely rare bird and, in all likelihood, the site's first transatlantic migrant. The last record in Herts was 10 years ago in 2015 at Tring Reservoirs. While I enjoyed seeing the chat, photos and videos as everybody caught up with the bird it was a painful experience as I sat in Cornwall toying with the idea of a 12-hour round trip to see the bird. I didn't succumb to such madness but made the most of my time in Cornwall instead. The bird was last seen early on Friday 3rd October and, despite searching on my return, has not been seen since.
I should say, regardless of my personal disappointment, this is an excellent record for the site and once again underlines the fact that Stanborough Gravel Pits is a fantastic magnet for birds! Long may it continue! The first week and a half of March saw some much warmer weather with temperatures reaching a heady 18 degrees Celsius. South-easterlies also felt promising but those elusive Spring migrants are still awaited. New planting has begun (following and perhaps prompted by the recent hedge destruction) and hopefully new good habitat will grow up along the track bank in time. Despite the lack of Spring migrants a few highlights have headlined the period and are indicative of the changing season. New for the year, a Shelduck appeared for one day on 2nd and another 2 on 11th. Also new for the year, up to 3 Barn Owls have been present on site with one regularly hunting the back of the turnip field. The real highlight came today, along with the 2 Shelduck, in the form of 2 Redshank feeding along the edge of the main pit. Hopefully harbingers of more wader passage and certainly an expected arrival in early Spring. Along with the Shelduck and Barn Owls, they take the site year total to 89. The first White Wagtail of the year was also with the Pied Wagtail flock. The Redshank feeding on 11th Mar Otherwise, the usual parallel trends of growing flocks of winter birds feeding up before leaving and others pairing and courting with a view to breeding have been evident on site. The Fieldfare flock enjoying the turnip field has stabilised around 200 birds while Common Gull numbers have diminished being replaced by increasing numbers of Black-headed Gulls.
A female-type Marsh Harrier was seen on 7th and on the same day at least 24 Common Snipe were flushed from the main weedy area along with at least 3 Jack Snipe. In the same area a single Stonechat was last seen on 3rd and may be the last sighting until they return in late summer post breeding. On the water, wildfowl numbers have generally fluctuated day-by-day but overall have increased. Around 30 Teal, 5-10 Wigeon and up to 50 Shoveler remain on site along with up to 20 Gadwall and well over 30 Tufted Duck and just one Pochard. Mandarin Duck number remain around 12 birds with a peak of 16 on 7th but mostly now paired up. A Great Crested Grebe visited again on 3rd and a pair of Little Grebes are now exploring nesting sites around the deep pit. Coot numbers have risen to at least 5 birds and their calls are now heard constantly as they begin courtship. The last half of February proved very quiet with little to report and many of the same birds present. However, a returning Oystercatcher arrived on 23rd and stayed until the next day - a welcome boost to morale as Spring tarries! The site would appear suitable for them to breed but, being relatively new habitat and in constant flux, the site may not hold enough food for them. Either way, the Oystercatcher brings this year's site total to 86. Other wading species were in short supply with a maximum count of 11 Snipe flushed on 20th along with 2 Jack Snipe - presumably the same birds recorded earlier in the year. Up to 80 Lapwing remained in the area along with 2 Green Sandpipers favouring the long drainage pit as usual. An adult Yellow-legged Gull joined the gull roost on 23rd and appeared to be a different bird to the one on 4th being a heavier, possibly male, bird. Wildfowl numbers have fluctuated, presumably in response to varying levels of disturbance at the site. Mandarin Duck numbers have grown to 12 birds with Wigeon fluctuating between 20 to 50 birds. A noticeable influx of Teal occurred with a peak of c150 on 24th but all virtually gone by the end of the week. Tufted Duck numbers also peaked at 19 birds on 24th and varying numbers of Shoveler (max 21) and Gadwall (max 10) were present. A single Pochard visited on 22nd while a Little Grebe has been seen on a couple of occasions. Two Great Crested Grebes were present on 26th and 2 Coot remain on site. Another Little Egret made a brief appearance on 23rd. Perhaps more noticeable on site has been the flocks of birds gathering to feed in the large sheep fields. Common Gulls have been passing through with the flock peaking at about 300 birds on 20th. The most dramatic flocks have been the Woodpigeons with some Stock Doves and Jackdaws mixed in. Several flocks of around 1,000 birds commute between the surrounding fields and virtually cover the crop when they land! Woodpigeons feeding on the turnip tops A smaller flock of c100 Fieldfares also remains in the field. These flocks of course attract predators and 2 Peregrines have continue to visit the site but, as yet, no Merlin. Last year's wing-tagged Buzzard has reappeared and at least 2 Ravens have been seen flying over the site on a few occasions. Another noticeable change - very much in line with previous years - is the growing flocks of Pied Wagtails and Meadow Pipits visiting the water's edge. Hopefully these in time will harbour White Wagtails and maybe some scarcer pipits. Passerine activity is more noticeable with the approach of Spring and both Yellowhammers and Reed Buntings are now singing on site. They will hopefully breed but one major set-back for all passerines has been the sudden removal of the willow hedge between the ruin and Symondshyde Farm. Aside from providing shelter and nesting opportunities for many birds the hedge-line also provided a valuable corridor into an otherwise shrub-less site. The track between the hedges also held a variety of butterflies not found elsewhere on site. It is not clear why the hedge was ripped out and hopefully it will be allowed to re-grow but equally it may be ploughed in and replaced with a fence. A real loss at the very start of the breeding season. The good news is that March has arrived and with it the promise of Spring migrants. We'll hopefully soon have the calls of Little Ringed Plovers on site with Sand Martins and Swallows overhead. Last year March saw some excellent birds so let's see what this year brings!
Despite the cold and quiet past few weeks of February little signs of Spring are beginning to creep in to view. Easterlies have dominated the month so far with temperatures struggling to get above 5 degrees Celsius. The cold, overcast conditions have not proved conducive to early Spring passage but finally, mid-month, it feels like we may be on the brink of Spring. The sun actually came out yesterday and this coming week promises a new and warmer weather system. By the last few years' standard, returning Oystercatchers are now officially late but little clues to early movement have appeared. Today the lone and patient Coot was joined by another - I assume they can now get to the business of courtship and nest-building but I'm sure challengers will arrive! Tufted Ducks have returned with numbers now up to 13 birds and just yesterday, 3 Mandarin Ducks arrived with 5 today. Despite their love of parkland pools with mature trees for their nests these ducks seem to really enjoy the bare gravel pits and appear to find plenty to nibble at on the stony ground. Wildfowl numbers in general have fluctuated and never seem to have recovered from the shooting onslaught unleashed by the farmer on his pet Mallards. Unfortunately, the more savvy wild ducks are quick to leave and while occasionally visiting soon vacate the site once they spot human visitors. These have included around 30 Wigeon, similar numbers of Shoveler, a few Gadwall, a single male Teal and female Pochard. Other regulars have included the 2-3 pairs of Stonechats, 2 Green Sandpipers and varying numbers of Egyptian Geese arriving to roost in the evenings. A high count of 24 birds was noted on 5th Feb. A Chiffchaff was also foraging with the Stonechats on 5th. Highlights of the first few weeks of February include 2 Jack Snipe flushed along with 10 Common Snipe on 10th Feb and an adult Yellow-legged Gull on 4th Feb. A Little Owl was also calling from its usual area on 5th and a Little Egret was noted on 1st Feb. A Great Crested Grebe on 8th Feb and a pair of Grey Partridge on 9th were also new for the site year list. With a pair of Red-legged Partridge seen on 15th the site total now stands at a healthy 85 for 2025. One final highlight of the month so far has been the continuing sighting of Marsh Harriers with a wing-tagged bird on 13th and a male on 14th. The male has been presumed to be an immature - possibly a 3rd calendar year bird - with contrasting underwing and dark trailing edge to it wings. However, it does not appear to be the same as a similar bird seen in November 2024 that had darker wings with dark ends to its tail feathers. In addition a full adult male was seen on 26th June last year along with a juvenile and female bird. Assuming some of the sightings are of the same birds it seems that there may have been 5-6 individuals involved over the last 12 months. With records in every month for a whole year it seems to bode well for a possible breeding attempt somewhere in the area at some point. Below are 4 of the birds seen over the last year: Having recently been introduced to a paper on Marsh Harrier identification I am less sure about ageing Marsh Harriers as the paper suggests it is nigh on impossible! The paper can be found here and makes for interesting reading.
Whatever the case, hopefully these birds will continue to be seen in the area and one day stay to breed. You always know it's been a quiet end to the month when Coot headlines the blog! However, this bird that turned up on 31st Jan is the first one of the year and signals the start of some spring movement of birds. Many more will follow and, hopefully as in years gone by, will breed at the site. The last half of January was quiet but the site list grew steadily to 77 by the month end with singing Mistle Thrush added and 3 Pochard on 31st. A pair of Pintail on 24th was a nice surprise along with 55 Wigeon, 27 Gadwall and a few Shoveler. A pair of Peregrine were also in the big field on that day and at least 5 Stonechats were on site. The regular immature male Marsh Harrier came through the site on 31st whilst the Skylark flock has held at about 50-60 birds along with up to 200 Fieldfares. Mute Swan numbers have fluctuated but tend to be around 15 birds and Lapwing numbers have varied from 30 to 100 birds. A couple of Green Sandpipers continue to favour the site, commuting between the long drainage pit and pools in the arable fields across the road. Gulls continue to provide a bit of interest although the 3rd winter Caspian Gull seems to now be favouring Tyttenhanger Gravel Pits a few miles away. A possible adult Caspian was present on 29th but at distance it wasn't possible to be 100% sure and, despite the nice clean head and darker grey mantle, I couldn't rule out a hybrid bird. Some video-grabs of the possible adult Caspian Gull on 29th Jan 2025 On the passerine front, Linnet, Goldfinch and Chaffinch numbers have dwindled and only about 20-30 Meadow Pipits are in evidence. A couple of Reed Buntings have also been mixed in with the flock along the track. February beckons and with it the hope of some migrant waders arriving at the site - hopefully Oystercatchers but maybe also Dunlin and Redshank.
Two weeks into the year and the Stanborough Gravel Pits year list has climbed to a healthy 60 or so species. New Year's day saw terrible wet and windy weather and yet a few of the regular species could be found - Green Sandpipers, Stonechats, Wigeon and the a Little Grebe. The highlight of the day was a lone Golden Plover battling low against the wind and rain. A larger group of nearly 30 were then seen on 9th with 3 on the field near the model airstrip. A Marsh Harrier put in an appearance on 6th and a Jack Snipe was flushed on 12th. An unusual sighting on 13th was an Alexandrine Parakeet flying over the site with the regular flocks of Ring-necked Parakeets. Freezing conditions gripped the pits in the second week of the year and the main pit froze over save for a small pool. While wildfowl numbers weren't as high as expected a surprise aspect of the freeze was a big increase in Mute Swans with 26 on 12th. The first really good bird of the year appeared (albeit distantly) on 16th in the form of a Short-eared Owl. Not recorded in 2024 it is really pleasing to get one in the first winter period. It appeared to come up from near Cromer Hyde Farm where owls were present in 2023 but headed off NW gaining height all the time. Hopefully it won't be the last sighting this year.
The year finished with a variety of highlights - mostly interesting birds that lingered or reappeared and one final new species for the year in the form of 2 Jack Snipe flushed on 27th December along with at least 6 Common Snipe. Good to know they are still visiting the site and they take the site total to 131 for the year. A Little Owl was in its usual hole (pictured) on 7th December however, the next day, Storm Darragh brought its tree down and the hole now sits just a foot above the ground! Subsequent visits have revealed new droppings at the lowered hole suggesting the Little Owl may have continued to visit the hole despite its toppling. On the water, wildfowl numbers grew with at least 20 each of Shoveler and Gadwall and the occasional single Tufted Duck and Pochard. Diving ducks seem to have pretty well vacated the site this month but the male Pintail stayed on until at least 29th Dec while Wigeon numbers peaked at 55+ mid-month. At least one Little Grebe remains faithful to the deep pit. The Caspian Gull reappeared on 24th along with an adult Yellow-legged Gull, the former then staying with the gull roost until 28th. From left to right: the 3rd winter Caspian Gull, the Caspian Gull showing primary wing pattern & the adult Yellow-legged Gull The immature male Marsh Harrier put in an appearance on 18th while a lone Golden Plover flew around the site on 26th. Otherwise it was business as usual with up to 4 Green Sandpipers remaining on site and a flock of c80 Lapwings split between the deep pit and the new workings scrape. At least 4 Stonechat stayed on the weedy areas while the 100-strong flock of Linnet continued to enjoy the seed-heads on the restored areas. A final highlight, particularly as they don't seem to common this winter, were 3 Lesser Redpolls (soon to be demoted to simply 'Redpolls') that were feeding on the alders along the Coopers Green Lane border. Lesser Redpolls
After a quiet autumn period the first week of November saw some welcome variety with a steady trickle of migrant birds visiting the site. Unsurprisingly, easterly winds dominated the period and, as usual, seemed to change things up. A male Marsh Harrier on 3rd Nov seemed to herald a few arrivals - 3 Wigeon that increased to 4 on 7th, at least 5 Golden Plover flying around the site and a huge flock of 400+ Linnet in the fields. In addition, a peak count of 8+ Common Snipe on 3rd joined up to 6 Green Sandpipers, a flock of 60+ Lapwing and up to 3 pairs of Stonechat around the site. The young male Marsh Harrier hunting at the far end of main pit The 4th Nov saw the arrival of a Dunlin and the 5th a smart adult female Shelduck. The Barn Owl was also back at its hole that evening. An adult Yellow-legged Gull joined the afternoon roost on 6th November. The gulls seem to like the newly scraped exposed mud on the edge of the deep pit. The area also looks good for waders and maybe will be as the ground matures and provides more invertebrate food. The main pit however is clearly still attractive to waders with a Redshank appearing on 8th Nov. The real highlight of the week however came on 9th Nov with the discovery of a smart male Black Redstart that spent the day hopping around the newly formed earth bank along the track. While it had gone the next day many local birders were able to see it and it becomes #128 for the site year list. A few more shots of the obliging Black Redstart on 9th Nov While the Black Redstart charmed another bird puzzled - appearing to be the site's first Caspian Gull, closer scrutiny suggested it may have been a hybrid with a Herring Gull. The bird gave a very 'Caspian' vibe with its bulk, extremely long legs and white head. It also had a nice white underwing and clean black tail band in flight. However, small notches on its tertial feathers, heavily chequered inner greater coverts and heavy anchor-marked scapulars suggested at least some Herring Gull influence. Despite the bird's stand-out 'presence' among the other gulls it sadly does not make it on to the site list. It surely must soon though! Regardless of the disappointing outcome the Caspian-type gull provided further education on the pitfalls of gull ID and the challenge of pinning down pure species. Equally, the first week of November was by no means disappointing and delivered a welcome variety of birds to spice things up after a dull autumn!
September and October proved to be very quiet as far as autumn migrants were concerned and in that respect a little disappointing. However, on a positive note, heavy rainfall quickly re-filled the main pit and other areas such that plenty of open water with muddy margins still remains. In addition, quarrying operations have by and large ceased for the winter period leaving the site relatively undisturbed and ready for anything that might be passing. There have been some highlights however - the best perhaps being an adult Mediterranean Gull (first for the site this year) that joined the gull flock on 8th Oct. The gull flock also attracted an adult Yellow-legged Gull on 26th Sep. A flyover Great White Egret on 30th Sep took the site total for the year to 127 species. Marsh Harriers continue to visit the site with the possibility of up to 3 different birds - a juvenile, a young male and a female. Single records came from 30th Sep, 8th & 16th October. Saturday 2nd Oct saw 3 Ringed Plovers visit briefly which, along with arriving Lapwing (62 on 21st Oct), Common Snipe (10+ on 11th Oct) and up to 3 virtually resident Green Sandpipers, were the only waders recorded in October.
Summer migrants had pretty well gone by the end of September with the last Swallow seen on 11th October. The last Hobby was seen on 30th Sep and a Wheatear was present on 28th Sep with House and Sand Martins having gone early in September. The usual winter arrivals have taken their place with at least 3 pairs of Stonechats regularly on site and a few Teal, Shoveler, Gadwall and Tufted Ducks making an appearance, albeit in very low numbers. Sep 24th saw the first 2 Wigeon with 3 together on 5th Oct. Perhaps the highlight for me has been a Barn Owl that has sat out in full view on a number of evenings, preening and stretching before heading out to hunt. Hopefully, the pits will see some more action soon - there's plenty of possibilities, among them Rock Pipit, Black Redstart, Short-eared Owls and, of course, rarer geese or swans. |
