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!

Stable periods of high pressure, easterly winds and very little rain have made for a slow passage this Spring.  Glaringly absent from the roll-call are waders such as Black-tailed Godwit, Ringed Plover, Curlew and Whimbrel.  But Spring is not yet over and there have been some highlights over the last few weeks.

Perhaps top of the bill was a female Marsh Harrier that spent a few hours early morning hunting over the middle pool on 26th April.  It was constantly harassed by Carrion Crows and Red Kites but nevertheless spent some time on the ground.  At one point it sat next to a Brown Hare and they just stared at each other!

April 21st saw a little bit of movement with the arrival of the first Common Sandpiper of the year and a high count of at least 6 Wheatears on site.  The Common Sandpipers increased to 2 birds on 6th & 7th May but just one remains on 11th May.  At least 3 Wheatear hung around but the last bird was seen on 6th May.

In other wader news, Greenshank have been a feature so far this Spring with singles on 21st, 22nd & 28th April followed by 3 birds on 7th May and another single on 11th May.  Unringed Green Sandpipers were also seen on 22nd, 27th & 28th April with a very late bird on 10th May.  It is likely that these are passage birds rather than from the local overwintering population.  Three Common Snipe were seen on 1st May and at least 2 remained on 7th May.  Little Ringed Plovers seemed to have settled into pairs with at least 4 pairs on site and starting to sit on nests.

April 22nd saw a Great Crested Grebe visit the site and the next day a late White Wagtail put in an appearance.  Good numbers of Yellow Wagtails remain on site but most seem to have paired up and moved out to the fields, hopefully to breed.  A pair of Meadow Pipits have also been displaying and favouring the weedy area so it's hoped they might breed too.  A common species in the winter they are a scarce local breeder.  The site's resident pair of Grey Partridge were seen on 23rd April and again on 11th May.

Swifts arrived back on 26th April with at least 8 birds present.  Thereafter they have once again become a regular feature of the skies with overcast weather bring a flock of over 100 in the past weeks.  Sand Martins have established at least 12 holes in the quarry workings with at least 30 birds regularly on site.  Hopefully their nests will be unaffected by quarry works.

In non-bird news, Brown Hares continue to be abundant on site but less visible now the crops have grown and courtship is dying down.  Painted Lady butterflies have been seen along the track a few times while a Small Copper butterfly was seen on 1st May.

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 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!

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.

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. 

It feels like it's been a slow autumn passage this year at Stanborough GPs but that may also be to do with the continuing in-filling work at the pits.  Very little open water is left but just enough to retain the Mallards and a surprising number of Little Grebes (10+).

The expected passage of Wheatear peaked on 8th Sep with at least 7 birds on site and a Whinchat too.  Notable too has been the evening roost of Egyptian Geese which rose to a record 65 birds on 11th Sept - possibly a County record.  The species seems to be going from strength to strength and may well be set to overtake Greylag Geese populations.

The evening of 13th Sept saw the largest flock of Meadow Pipits this autumn with over 200 birds flying around the site and over the main field.  With just one of two birds on 11th these birds are fresh in from the north.  An additional highlight of 13th was a flyover Golden Plover that dropped down into fields south of Coopers Green Lane.

The same evening also saw a roosting juvenile Dunlin at the site (see title picture) and an arrival of at least 7 Mandarin Ducks to roost - absent from the site in the last month.

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.
