A total of 84 species today - LGRE Diary Notes































FRIDAY 29 APRIL (ROYAL WEDDING DAY)

Two heavy showers crossed the Chilterns just as the day was dawning being blown in by the continuing NE wind. It then remained very grey throughout much of the morning before the wind veered round. The afternoon was much brighter, with intermittent sunshine, but at around 1600 hours, an almighty thunder and lightning storm passed through eventually giving way to much warmer conditions and clearer blue skies.

Spurned on by Tina and Sue, I decided to try my luck at a local daylist, but drove around the sites rather than walked as those two intrepidly did. I was somewhat disappointed by my tally - just 84 species.....

Far more disappointing though was missing all of the Bar-tailed Godwits and Whimbrels (80 and 4 respectively) that passed through Wilstone Reservoir prior to 0845 hours (see Dave Bilcock's list of sightings elsewhere on this blog)

COLLEGE LAKE BBOWT (BUCKS)
(0800-0848 hours)

Following up on Dave's earlier text messages, by the time I got to College, just 1 of the 7 BAR-TAILED GODWITS was still present - a cracking full summer-plumaged male feeding on the main marsh just in front of the new hide (see Dave Hutchinson's superb image). And despite the fact that over 80 individuals had passed over between 0530 and 0845 hours, this was the only bird that I was to see all day.....incidentally, it represented my 139th species in Buckinghamshire this year

In addition to the godwit, I notched up the following 19 species -:

Great Crested Grebe (pair still on the deep lake)
Mute Swan (pair on the marsh)
Atlantic Canada Geese (several including one pair now with 7 goslings)
Mallard, Gadwall (pair), Shoveler (3 drakes), Tufted Duck (19), Moorhen and Coot
Lapwing (15+ including young)
OYSTERCATCHER (pair still present, the female sat on a nest)
Common Redshank (4)
LITTLE RINGED PLOVER (pair)
Lesser Black-backed Gull (3 adults over)

Woodpigeon (5)
COMMON CUCKOO (again calling from fen area)
Wren, Common Whitethroat and Blackcap

WILSTONE RESERVOIR (HERTS)

A Song Thrush carrying food flew across in front of me by the sewage farm as I drove with great expectations to Wilstone, particularly as DB had seen several flocks of Bar-tailed Godwits and up to 3 Whimbrels a little earlier. I met Francis Buckle at the top of the steps and he informed me of an interesting flava wagtail he had just seen and that Ian Williams had first seen on Monday. I stood for a while checking the reservoir, adding Carrion Crow, Jackdaw, Linnet, Goldfinch and House Sparrow to my day list, as well as the two continuing drake Eurasian Wigeon, several Greylag Geese, Grey Heron, Cormorant, 80+ Common Tern, the single adult BLACK TERN (perhaps new), 6 COMMON SWIFTS and all three hirundines - Barn Swallow, Sand Martin and House Martin.

Walking then on to the overflow corner added Long-tailed Tit (3), Blue Tit, Chaffinch, Dunnock, with a singing male Common Chiffchaff in trees behind the Drayton Bank hide.

I then met up with Dave Bilcock at the bend just beyond the old cressbeds at the back of Wilstone where he quickly showed me the wagtail. It was a very nice male BLUE-HEADED-TYPE WAGTAIL and was paired up with a female YELLOW WAGTAIL (Dave managed a nice shot of it); the bird was favouring the line of fenceposts that lead away from the bend towards the Dry Canal. A single Eurasian Skylark also perched on one of the posts too. No sooner had I joined Dave then I missed a flyover Whimbrel - Francis watched one from the car park steps.

Between the car park and the Hide Meadow, 4 singing male Common Whitethroats were noted, with Jackdaw, CETTI'S WARBLER (singing bird), Mistle Thrush (singing male), Red Kite and a single drake Northern Pochard noted as we both walked back to the car park.

Once again I stood in hope for some more waders but it just didn't happen - a HOBBY was seen, a male YELLOW WAGTAIL flew NE and wildfowl included 6 drake Gadwall and a single drake Shoveler.

ASHRIDGE FOREST (HERTS)

Whilst scanning the skies for waders, Ben Miller texted to say that he and his daughter were watching the Clinksmere Pond TREE PIPIT - and that it was showing very well. Less than ten minutes later, I was with them both, but despite spending yet another two hours searching for this highly elusive and skulking tree and ground dweller, I failed in my quest to relocate it.

The Monument Drive did however provide me with Robin, Great Tit, Coal Tit, Goldcrest, Nuthatch, Common Treecreeper, Common Blackbird, Stock Dove and Common Chiffchaff for the day and a very showy female Muntjac. Much more distressing though was the sight of a female Fallow Deer run over and killed just east of the access road.

IVINGHOE HILLS NNR (BUCKS)

Moving around to Top Scrub, several more species were added, including an excellent array of warblers. As others have commented, GARDEN WARBLERS abound there this spring with at least 7 males in full song, also several Willow Warblers and Common Whitethroats and a rattling male Lesser Whitethroat. A few Common Chiffchaffs were also singing from the scrub, with a Long-tailed Tit with food, the usual pair of BULLFINCHES, Jay and Common Magpie. A pair of Common Pheasants frit the life out of me as they exploded from the ground cover. Displaying Meadow Pipits were near the S-bend.

DOWN FARM AND PITSTONE HILL (BUCKS)

I then did my regular circuit between Pitstone Hill car park and the Down Farm entrance track, taking in the perimeter fence around the fields. There was no shortage of Skylarks (25+) nor of Rooks to-ing and fro-ing from the Aldbury Rookery, whilst several pairs of Linnets were encountered, more Meadow Pipits, the local pair of Common Kestrels and a pair of Yellowhammers in the roadside hedge. There were five singing male Common Whitethroats (two within a few yards of each other by Down Farm entrance track and a further three males in the roadside hedge back to the car park) whilst two migrant House Martins went north over Pitstone Hill.

Most disconcerting though was the total lack of Corn Buntings - not a jangler to be heard anywhere - the first time I have failed to find this species here in spring.

In Aldbury village, the House Sparrow colony was still intact at Hill View.

COLLEGE LAKE BBOWT (BUCKS)

I returned once more to College Lake, where at 1300 hours the BAR-TAILED GODWIT was still present. This time I saw both male and female COMMON SHELDUCK, a single drake Eurasian Wigeon (on the deep lake), 4 Shoveler (1 female) and a COMMON SANDPIPER

Nearby at Pitstone Industrial Estate, 18 Common Starlings were feeding on the grass verges.

MARSWORTH RESERVOIR (HERTS)

Several Eurasian Collared Doves were seen in Marsworth village, whilst the reedbed and small wood adjacent to the reservoir yielded Song Thrush (singing male), both Sedge and Western Reed Warblers, a male Willow Warbler, a male Reed Bunting and on the reservoir, 5 Great Crested Grebes, a female RED-CRESTED POCHARD with one survivng chick (see Francis Buckle's images) and the male Grey Wagtail carrying food back to the nest.

STARTOP'S END RESERVOIR (HERTS)

My only Black-headed Gull of the day - an adult in breeding plumage - was here, with 4 Great Crested Grebes, 2 Mute Swans, 4 Greylag Geese, 55 Tufted Duck, 2 Pied Wagtails and 14 Sand Martin the only other birds of note.

TRINGFORD RESERVOIR (HERTS)

Very, very quiet with just 1 Great Crested Grebe, a pair of Mute Swans nesting and a female Mallard with five chicks.

THE DRY CANAL FIELDS (HERTS)

Walked from Drayton Beauchamp canal bridge east to the first wooden bridge across the canal where I located a pair of nesting Long-tailed Tits, two singing male Yellowhammers, several Goldfinch and Linnet, a further 3 singing male Common Whitethroats and a Mistle Thrush. A pair of Mallards accompanied two chicks, with a second female with 6 chicks.

In the field immediately south of the Dry Canal, a single male NORTHERN WHEATEAR was still to be seen, along with 3 Stock Doves - whilst a male LESSER WHITETHROAT was rattling from the hedgerow.

I finally located a male Greenfinch - singing from the tall Ash tree at the junction of Little Tring Road and the main road.

IVINGHOE HILLS (BUCKS)

During the afternoon, the sun finally came out for a short while and I took this opportunity to catch up with some local butterflies I had not had the chance to see yet this year. Walking the ''Duke Gully'' was very productive, yielding 7 very fresh DUKE OF BURGUNDY FRITILLARIES, an early Small Heath, an early SMALL BLUE, 6 DINGY SKIPPERS and a single GRIZZLED SKIPPER. Another LESSER WHITETHROAT was heard and more Common Whitethroats and Linnets.

DAGNALL (BEDS)

The nesting pair of COMMON RAVENS were very busy feeding young, the female now being very heavily worn in the wing. The only Common Buzzard of the day was near Well Farm.

After that it all fizzled out really with a very sudden lightning storm not producing any new migrants but a lot of rain and flash-flooding. The smell of the Bluebells in the now famous wood along the Beacon Road after the rain was incredible.

Late Additions: Common Kingfisher was added from yet another return visit to College and a visit to the Wendover Arm of the Grand Union Canal produced the only Little Grebe of the day and Great Spotted Woodpecker.

So, a total of just 84 species - I missed Whimbrel, Green Woodpecker, Common Teal, Tawny & Little Owl, Sparrowhawk, Marsh Tit, Corn Bunting, Mandarin Duck and Red-legged Partridge - Firecrest too

BAR-TAILED GODWITS galore !!













A fantastic morning's passage of BAR-TAILED GODWITS through the reservoirs; these are all the birds that I have seen (+1 by Ian W), a total of 80 birds.

2 Wilstone 05:30 (found by Ian and Roy, one bird sitting on the bales)
5 W 05:50 (above birds joined this flock and circled reservoir several time before heading off)
7 College Lake 06:55 (flock landed on the marsh)
17 CL 07:20 (6 of the above birds joined this flock as they flew over)
22 CL 07:26 (initially seen at Wilstone by Stuart)
19 CL 07:26 (again came from Startops direction)
3 CL 07:40 (initially seen by Stuart at Wilstone)
1 CL 07:45 (accompanied by a whimbrel)
1 W 08:30
1 W 09:25 (seen by Ian Williams only)

A couple of pictures of the barwits on the marsh at College Lake are published above, of which 5 of the 7 were breeding plumaged males. Dave Hutchinson's shot at the top was of the male that lingered all day

Today's TREE PIPIT in Ashridge

Steve Blake very kindly sent me this image of today's very elusive TREE PIPIT in Ashridge Forest

No sign of Ashridge Tree Pipit this afternoon

THURSDAY 28 APRIL

Another very cold day with the wind remaining ENE and quite strong at times. Very cloudy and grey early on but then much brighter this afternoon. Everywhere still very dry, with the ground baked hard. BAR-TAILED GODWITS were the order of the day with 9 birds locally, four of which lingered to allow many birders to connect.......

ASHRIDGE FOREST (HERTS)

Dave Bilcock phoned me to say that he had seen Ian Bennell's Tree Pipit up by Clinkmere Pond but that it was extremely elusive. Apparently Ian had relocated it, allowing DB, Francis, Mike Campbell and Graham Knight to get on to it. Not once did it call or sing - just skulk in the vegetation or perch low down in the Birch scrub. With Tree Pipit being the local mega that it has now become, I made my way over and spent at least two hours this afternoon searching in vain for it. I could not relocate it, despite it being fairly quiet and undisturbed.

WILSTONE RESERVOIR (HERTS)

A single BLACK TERN and 4 ARCTIC TERNS were all of note on a very cold and windswept North Bank

Lee G R Evans

BAR-WITS through Tring too......

At 5:50 a BLACK TERN appeared in front of David and I this morning. This was closely followed at about 5:55 by two BAR-TAILED GODWITS (male and female), they circled for about 15 minutes and departed NE and were lost to sight at about 6:10. This brings my reservoir year list to 130 – my best ever for the January to April period.

The harrowed field still had two Wheatears in it and a Lesser Whitethroat was singing in the hedge by the kissing gate on the footpath at the top of that field (Roy Hargreaves)

ARCTIC TERNS







ARCTIC TERNS still present at Wisltone this evening, frequently perching on the bales (Dave Bilcock).

ARCTIC TERNS arrive on the NE winds

WEDNESDAY 27 APRIL

The wind veered more Northeasterly this morning and as a result, ARCTIC TERN passage began across the Midlands and East Anglia. It was very cold this morning but warmed up slightly this afternoon when the skies cleared and the sun shone brightly.

FLAUNDEN (HERTS)

Two 'new' singing COMMON WHITETHROATS found this afternoon, both within 100 yards of each other close to the sharp bend at the north end of Flaunden Bottom (at TL 007 007). It has been an exceptional year for this species so far and looks set to be a record year in my Recording Area.

WILSTONE RESERVOIR (HERTS)
(evening visit, with Geoff Young & brother, Ian Williams, Chaz Jackson, Jenny Wallington, Sue Rowe, Dave Bilcock, Paul Eels, Kevin Holt and others)

With a switch to moderate Northeasterlies, ARCTIC TERNS were the order of the day with 9 present this evening (DB et al); also a pair of breeding-plumaged BLACK TERNS and 52 Common Terns. In fact it was a bit of an 'Arctic Tern Workshop' as I tried my best to explain the subtle differences between the two species. Although many of the Arctic Terns were far from fully developed into breeding plumage, with split or uneven tail streamers, separation was best explained by the grey underparts (particularly the breast), very short and darker red legs when perched on the algae bunds), strong contrast between the white trailing edge and darker grey upperwings in flight, much narrower wings and more agile and graceful flight pattern and mostly all red bill (although some Arctics did have black towards the tip). Intriguingly, the two BLACK TERNS were a pair and displaying at times.

Apart from the terns, very little of note: 40+ COMMON SWIFTS high in the sky and a male YELLOW WAGTAIL that flew NE across the reservoir
