While the search for the recent Pectoral Sandpiper proved predictably fruitless it did however yield some nice autumn birds.  I'll take these as consolation prizes and proof that it's worth keeping looking.

First up, were 4 Stonechats followed by a late first-winter Wheatear enjoying the newly dug drainage pipe mounds.  Skylarks and Meadow Pipits continue to move through the site along with an increasing number of Reed Buntings.  Three Little Grebes continue to frequent the deep pool along with a Grey Wagtail and it was while observing this latter bird that I notice the star bird of the day - a Rock Pipit!

A pretty scarce bird in the county, Stanborough Gravel Pits does well for this species with Rock Pipits visiting annually and this the second record of the year following a Spring bird on 16th March.  In classic form, it crept along the edge of water, taking a bath at one point before preening on the bank.

Some photos of the Rock Pipit with a video of it preening below.

I mentioned the Wheatear enjoying the newly dug drainage pipes and this work represents another major step in the site's 'restoration' to farmland.  Many hundreds of metres of perforated pipe are being laid underground every 20 metres or so on all the slopes.  These then feed into main drain pipes that will take run-off water to both the main pit and deep pit.

While the work is fascinating to watch I can't help feeling that an awful lot of plastic is being buried in the soil and that good old-fashioned ditches might have been a more environmentally suitable solution.  Whether these drains work long-term or not remains to be seen and hopefully some water-logged areas will remain for over-wintering Snipe and Jack Snipe.

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.

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!

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.

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.
