With work and being away I've got a bit behind so a brief summary of late August and early September highlights below.

18th August - the site's first Black-tailed Godwit of the year finally made an appearance, with another 2 joining it on 20th.

19th August - the Barnacle Goose was present again with the Canada Geese flock and then again on 24th.

22nd August - the site's first Spotted Flychatcher since Sep 2021 was found near the horse paddocks and then another bird by the long drainage pit on 30th.

23rd August - a juv-type Marsh Harrier was seen and a Sedge Warbler was present in the main weedy area.  At least 7 Yellow Wagtails were recorded as well.

24th August - the first 3 Meadow Pipits of the autumn appeared in the evening, coming down to drink and bathe at the edge of the main pit.  A Common Snipe was also feeding at the water's edge and Stonechat numbers rose to 4 on site.  Five Swifts were also likely some of the last to be seen this year at the site.

27th August - a Wood Sandpiper was found in the long drainage ditch with a high count of 5 Green Sandpipers and 3 Common Sandpipers.  The 4th record of the species this year.
A Wheatear was also present and found the next day too.

30th August - a Whinchat was on the new fence along the main track.

31st August - a Mandarin was present on the main pit - perhaps the last for a while?

4th September - a juvenile Little Ringed Plover was probably the last for the year.  At least 10 Chiffchaffs were seen feeding in the willows over the long drainage pit water - an area that's proving very attractive to passage birds.

7th September - the arrival of a juvenile Little Stint along with a Ringed Plover brought welcome interest to the site with the stint a site year tick.  The Barnacle Goose made an appearance along with a Reed Warbler and Lesser Whitethroat feeding in the long drainage pit.

8th September - 3 Whinchat were found and rose to at least 4 birds on 12th Sep.  These birds continue to be present on the site along with up to 6 Stonechat.

13th September - while Yellow Wagtail numbers were at 7 again, Meadow Pipit numbers had risen to at least 40 birds on site.  Swallow & House Martin passage is now a continual feature of the site along with the odd Sand Martin.

May 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.

The 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.

​With still no rain, nor any forecast, water levels have dropped naturally, exposing lots more mud.  Despite good waders turning up at other sites not too far away nothing out of the ordinary has dropped in.  Two more Greenshank appeared on 15th and staying until 17th while the year’s first 2 Ringed Plovers appeared on 12th with another 2 present on 17th.  Little Ringed Plovers continue to display and stake out various areas of the site but, as yet, have not been pinned down to specific nests.

​A Marsh Harrier and a Hobby briefly on 16th were the only other highlights of the past week along with fairly regular visits from a Little Egret.  Sand Martins continue to number around 30 birds with at least 30 holes counted in the workings.  The first Mandarin female appeared on 15th with 6 new ducklings and no doubt we’ll see more in days to come.  Interestingly, at least 10 male Mandarins were found roosting on the pond in Dogsheart Spring copse.  It seems likely these are non-breeding birds (unless they really have left all the work to the females!).

​I recently spoke with a manager from Cemex the quarry operator and their plan is to continue the ‘restoration work’ shortly.  To that end they have installed a pump to remove water from the Deep Pit (on the left as you come in from Coopers Green Lane) and water levels are now falling rapidly.  Temporarily this exposes lots of nice mud but this will dry quickly and make way for the diggers to return.

​The plan is for the diggers to landscape the area leaving just a small kidney-shaped pond in the far left-hand corner.  The rest of the area will be smoothed with topsoil and will presumably be suitable for farming.  This of course is likely to mean the loss of deep water at the site perhaps making it unattractive to the Little Grebes and diving ducks.
 
The increased disturbance will also make it unlikely that Little Ringed Plovers will breed successfully in this area.  Thankfully other areas still remain available however, beyond this section of works, there are plans to drain the Main Pit (on the right as you enter the site from Coopers Green Lane) and continue with topsoil landscaping to restore as much as possible to farmland.
 
The site manager did express his reservations that water would be able to be controlled and fully expects that lakes will re-form after heavy rain.  Various elaborate pumping systems have been explored to take water off-site but no final plan is in place.  As I have mentioned before, trying to fight nature and take vital water off the land seems crazy and my hope is that nature forces the outcome!  When water is such a valuable resource and when flood zones are under increasing pressure it seems ridiculous that money and resources would be spent trying to pump water off-site and away to other systems.
 
Unfortunately, the plans are the product of many parallel thought processes and interests with little to unify them into sensible coherence.  Historic restoration plans do not seem to take into account current realities – such as the excellent habitats created by quarrying – and ecological assessments are species and habitat-obsessed such that the wider ecosystems and natural re-wilding processes are considered free to be sacrificed or ignored in favour of new planting.  Vested interests of landowners and managers that (understandably) seek profit and reward dictate that works are carried out to take advantage of current funding meaning that levelling everything and starting afresh can be the preferred option.
 
Hopefully something good will be left but for now it is best to enjoy it while it lasts!

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.

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.

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. 

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.

Starting with the 'low' and that is the inescapable fact that back-filling and 'restoration' work at the pits has continued apace.  The main pit has been drained using a pump system and just a couple of large puddles remain.  It is not clear yet how much of the pit they intend to backfill but at least half of it is ear-marked for re-landscaping.

It remains utterly baffling as to how this plan has been persisted with and, to me, appears to be a clear example of the absence of joined-up thinking.  The local farmers would have liked the water body preserved - they know they cannot farm this land as historically it has always collected water.  In addition, the local water company has been encouraging farmers to keep water on their land to avoid flooding downstream.  And yet, the gravel company has been told to persist with a plan of drainage and restoration involving pumping water off-site - something that, in all likelihood, will have to continue indefinitely.

All this while, an area rich in wildlife has been destroyed and the opportunity to create something really special for nature missed.  Of course, left to nature, that opportunity might return but once again, we as humans, seem set on fighting nature - to what end I don't know!

While water remains on site and large areas remain disturbed by diggers and the plough the attractiveness to birds and other wildlife continues at the site.  Passage this month has been slow but steady with the highlight a Wood Sandpiper on 12th August.

One or two Common Sandpipers have remained on site with varying numbers of Green Sandpipers.  Joining them occasionally have been up to 3 Ringed Plovers, 2 Little Ringed Plovers, at least 5 Common Snipe and a single Greenshank.

Away from the water's edge a juvenile Peregrine has been practising hunting over the site and a couple of Grey Partridges have reappeared following the harvesting of the fields.

August is underway and expectations have risen with each day that passes for this is the month of movement!  Or at least we hope so!

The pits are sadly being rapidly filled in and re-landscaped but open water with muddy edges remain not to mention the scrubby areas and arable land.  Longer term heavy rain may restore some water areas but in the meantime hopefully the autumn will bring some good birds.

Today the first Common Gull - a juvenile - was with the growing numbers of Black-headed Gulls and a bright yellowy Willow Warbler was along the track.  Both are signs that birds are moving through, albeit just a trickle at the moment.  In addition, the first Ringed Plover of the autumn made an appearance and at least one Common Sandpiper remains on site with up to 3 in recent days.  Unusual in previous years, 2 Common Tern have been visiting the site most days - an adult with a juvenile bird.

The last few weeks have seen a good passage of both Green Sandpipers (up to 9) and Common Sandpipers along with a single Dunlin on 2nd Aug. In addition a couple of Barnacle Geese have been regularly with the Canada Goose flock along with up to 17 Egyptian Geese.  At least 2 different Marsh Harriers have been visiting the site and sightings may constitute even more birds if they are just passing through.  Up to 3 Hobbies and a Peregrine have also spent time hunting over the site, stirring up the flocks of other birds as they go.

June is the pivotal month of the year when the compass swings slowly round from bringing us Spring migrants from the South to bringing us back Autumn migrants from the North.

As the last Ringed Plovers of Spring departed the first returning Green Sandpiper appeared on 15th with up to 3 birds on site subsequently.  Little Ringed Plover numbers also grew to at least 17 birds on 23rd June with apparent new arrivals from off site.  Lapwing numbers have also swelled during the month and the first Shoveler and pair of Teal appeared on 26th.

June 4th saw a young (2nd calendar year) Yellow-legged Gull on the deep pit - a species we will no doubt see more of as the the year progresses.

The anticipated wader 'drop-ins' began with an Oystercatcher on 15th followed by a Redshank on 20th.  Hopefully July will bring more waders and maybe a site tick in the from of a Spotted Redshank or Curlew Sandpiper!

A Great White Egret on 24th was the first for the year while a young male Marsh Harrier (pictured) briefly quartered the main pit weedy area on 26th.  This latter species has seen a huge increase in records over the last few years and maybe in time we'll see our first breeding pair.

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.

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.
