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.

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!

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.

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.

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.

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?!

They don't come much better-looking than this summer plumage BLACK-NECKED GREBE that spent the day of 19th March on the main pit!  A first for the site taking the all time total to 157.

The bird followed the arrival of 7 Pintail the day before and was joined on 19th by the first Dunlin of the year, coinciding with the arrival of very warm conditions on south-easterly winds.  Three Little Ringed Plovers were also on site along with a White Wagtail.  One observer also saw a Rock Pipit (possibly the same bird from 16th?) but others were unable to find it.  The site's first Mediterranean Gull for the year - a second winter bird - was also seen on 18th.

The warm conditions (18+ degrees Celsius) saw the site's first butterflies of the year too - a Comma and Small Tortoiseshell.  The 20th March saw further movement with Little Ringed Plover numbers up to 5 by the end of the day and a first winter Mediterranean Gull that slowly circled through the site without alighting.

The weekend ahead holds changeable weather including some heavy rain so could be a recipe for more arrivals.  The site year total now stands at 94 species.

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.

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.

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 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.

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!

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.

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.

A memorable day at Stanborough Gravel Pits that delivered some fantastic birds including 2 new species for the site!  For weeks the large, wet, muddy scraped area adjacent to the main pit had been looking perfect to attract something of interest and on 11th March it finally did.

On that particular day I was picking up my son from Heathrow following his travels abroad so ignored the regular ping alerts on my phone.  However, as we drove home, I couldn't help but notice the words 'Stanborough' and 'Brent Geese' on the screen.  I then explained to my family that on our return I would have to go out immediately but would be back as soon as possible to complete the family reunion!

I got to the pits by 11.30am and immediately got on the small group of 9 Brent Geese looking very at home on the muddy scrape, feeding and chasing each other about in typical Spring fashion.  A new addition to the site list at #153 but more was to come...

The news of 2 Curlew drew me back to the site after lunch and indeed, there they were, with the Brent Geese.  In addition, a couple of Dunlin and 3 Redshank had also dropped in making it clear that a proper movement of birds was underway.  A summer plumaged Black-tailed Godwit was seen flying around by some and was then present on site the next day.  The Brent Geese flew north along with the Curlew around 3.30pm and were later seen at Broom GPs in Bedfordshire.

With quite a few birders on site it was inevitable that more would be found and indeed one lucky observer saw a Lesser Spotted Woodpecker in the hedgerow trees along Coopers Green Lane.   Unfortunately no-one else spotted it but nevertheless another site tick taking the list to 154.  And still there was more to come - a White Wagtail was on site and, as the day drew to a close, a Scandinavian Rock Pipit was found at the far end of the long pits.

The pipit concluded a remarkable day when I felt I had to pinch myself to check I was in Herts and not somewhere else like Frampton RSPB in Lincs!  By the end of the day the site list had grown to 154 species and the site year list to 96.

The next day, while the Dunlin and a single Redshank lingered, four Rock Pipits were found on site feeding together!  The birds were always distant but included two birds transitioning into their beautiful pale summer plumage (see the rather distant 'record shots' below).
