Sunday 14th September saw me on site as usual following an excellent morning's 'vismig' at Potwells that included a flyover Woodlark!  A County rarity and one that I had hoped I'd catch up with this year.  The session also witnessed a noticeable increase in Meadow Pipit movement and this was in evidence at Stanborough too with in excess of 100 birds noted.

The usual Common and Green Sandpiper were on site and a flyover Raven too.  I commenced my usual scan from the track with my scope of the large weedy area adjacent to the main pit - a good way to pick up any migrant chats.  Sure enough, at least 4 Stonechats were on view along with a single Whinchat.

As one of the regular dog walkers approached I saw a little bird hop up onto a stem right at the back of the weedy area - about as far a way as it could be.  It cocked its tail up and I knew, without a doubt, that this was a DARTFORD WARBLER!  Immediately I was engaged in exchanging niceties with the walker while my mind began racing as I realised I needed to find this bird properly!

The walker moved on and I sent a couple of messages to Steve Pearce and Andrew Steele who I knew weren't far away saying that I thought I had a Dartford but I was going to have a look.  I quickly walked along the back edge of the weedy area at the field edge with ears and eyes peeled.  I reached the end with no joy and realised, in my haste, I hadn't really pinpointed where exactly I had seen the bird.  I decided to return to the track, wait for Steve, and in the meantime pin-down exactly where I had seen the bird.

Steve arrived and we both headed out along the edge of the weedy area again.  Reaching the end there was again not a squeak aside from the usual Reed Buntings, occasional Yellowhammer and Stonechats.  Steve decided to loop around the weedy area and as he completed his loop so the Dartford Warbler began scolding and hopped up on a stem about 20 yards in front of me!  Bingo!!

I quickly called Steve on his phone and he came over just in time to get fairly good views of the bird before it dropped back down into the thistles and weeds.  My second County Rarity in a day and a first for me, not just for my 5 Miles From Home List but also for my Herts List.  The Dartford Warbler was of course new for the site too taking the all-time total to a pleasing 160 species.

My first views were to prove some of my best and I managed a few hasty record shots (see the header photo) before it vanished.  Thereafter it became much harder to see, other than in brief flight views.  The following day, others were unable to locate it but I revisited on Tue 16th and was able to find it again moving along the back edge of the weedy area with a couple of Stonechats.  Again I was able to get a few record shots as it lurked in the undergrowth but never sat up.

Walking back to the car I noticed another little bird flying along, almost next to me but only about a foot off the ground.  I paused and eventually saw it in flight - a Grasshopper Warbler!  I waited while it rustled around in the grass just a few feet away from me and then watched it fly into the main clump of reeds in the wet area.  Another site year tick, taking the year total to 127!

​While I had been observing or (more truthfully) waiting for the Dartford Warbler to appear I had puzzled over hearing what appeared to be Dartford Warbler scolding from two different locations.  While the bird did move quickly through the undergrowth it nevertheless seemed odd.

Again, with no sighting by others the next day I returned on Thursday 18th Sep evening and quickly relocated the bird, except that this time my puzzlement was answered as not one but TWO Dartford Warblers flew up and across briefly, giving me just long enough to confirm my earlier suspicions.  While light also plays a part, I did think, looking at my record shots, that one bird might possibly be lighter and brighter in plumage that the other...maybe I had unknowingly photographed two separate birds?

I saw and heard a Dartford again on Sat 20th Sep along with Andrew Steele but it remains to be seen how long both birds remain on site.  While Dartfords are a possible candidate to over-winter at the site we are still in peak migration time so they may move on.  They will however, be remembered for the excitement they brought as a genuinely rare bird in the County.

Walking out along the weedy area also brought home what a fantastic (and really under-watched) area it is for small migrant birds.  On Sat at least 5 Chiffchaffs were feeding along the edge with at least 2 Whinchats and 4 Stonechats.  Two female-type Wheatears were also present with a third male seen in the morning too.  Meadow Pipits, Linnets and Yellow Wagtails are also dropping down into the grassy areas while passing Swallows, House and Sand Martins are making good use of the feeding opportunities.  Who knows what else may pop up?!

As a final note, a smart adult Yellow-legged Gull was by the deep pool on Sat afternoon but didn't stay long.

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.

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.

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.

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.

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!

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?!

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.
