Birding over the festive period

Yesterday went to Wendover Woods in the morning. Only birds of note were 2 COMMON CROSSBILLS heard flying over.

With Warren and Dave yesterday the Marsworth BITTERN showed quite well opposite the hide.

The gull roost is still quite low in numbers, although there have been 2 Herring Gulls in the last 2 days and 32 Lesser Black-backed Gulls on Sunday evening. This morning only birds of note around Tring Reservoirs was a male PINTAIL and the COMMON REDSHANK at Wilstone, and the female Red-crested Pochard at Startops (Steve Rodwell)

Ruddy Shelduck again

28 December: A female Ruddy Shelduck of unknown origin was at Wilstone early this morning.
4 Goldeneyes were also present (3 males and a female) (Dave Bilcock)

Weston Turville BITTERNS - 27 December

Excellent and prolonged views of two BITTERNS this afternoon at WTR. At one stage both birds were seen together. One bird walked into the main channel at about 16.15 and the second bird flew over its head into the reeds between the channel and the reservoir. The first bird stood in the channel skywatching for about 2 minutes before flying off into another channel out of sight. The second bird then appeared in the channel and spent about 4 minutes, also skywatching, before flying into the reeds. At about 4.50 something spooked a Grey Heron and a BITTERN out of the main reedbed and they flew off to the reeds on the opposite side of the reservoir from the (new) hide. The Bittern returned about two minutes later and flew into the reeds just to the left of the channel at the (new) hde end. Also several Water Rails - three were seen in 30 seconds at one point. A Brown Hare walked out into the cut area presumably to feed (Dave Parmenter)

BITTERN still

27 December: The BITTERN put in a late performance this evening at 16:20. Initially it was sat low in the reeds along the south bank, opposite the hide, before flying into the reeds nearer the SW corner (Dave Bilcock).

Saturday 26 December 2009

Two BITTERNS now at Weston Turville

Christmas Day: First BITTERN flew in low from far right of hide at 16:15 to roost in deep reeds to front left of hide. While watching excellent views of feeding and bathing Water Rail in unfrozen stream flowing through cut out in front of hide, a second BITTERN rose from the far edge of the reeds to the right of hide at 16:25 and flew to roost close to 1st bird. An added benefit of walking off the Christmas dinner...Pete & Ginny Weisner

Happy Xmas to all of my browsers




Chris Williams did very well in fading light to get these two record shots of the GREAT WHITE EGRET present briefly on 20 December.
Meanwhile on Christmas Day, both wintering EURASIAN BITTERNS are still present - at Marsworth Reservoir and Weston Turville Reservoir

Wednesday 23 December 2009

Complete whiteout - and a male HEN HARRIER

An adult male HEN HARRIER lingered about the east bank of Wilstone Reservoir this afternoon, scattering Meadow Pipits, Redwings and Common Blackbirds. It was last seen at about 1545 hours, when it was thought to have roosted in the reedbed.

Another BITTERN - at Weston Turville

EURASIAN BITTERN showing in cut in front of hide at Weston Turville Reservoir 14.20 today (Peter Garner)

BITTERN still on Marsworth

22 December: It was good to see the Bittern this afternoon still hanging in at Marsworth. I had intended to go to the gull roost after last nights effort in the snow failed to produce anything of note (although there were 92 Common Gulls present) but after skidding down the canal bridge near the mill even Wilstone Reservoir seemed like a long way to go. Most of the reed at Marsworth is flattened by the snow (hopefully it will recover when the snow melts). It is quite a sight and certainly seemed to confuse many of the Corn Buntings that couldn't make up their mind where to roost. Any bird roosting in the reeds would be very exposed. The Bittern showed up at 4.22pm on the edge of the reeds in the S.E. Corner. It then proceeded to do a lap of the reservoir before landing in the sallows out from the overflow (Steve Rodwell)

The first BRAMBLING returns to a Tring garden

18 December: Unsurprisingly with the snow the number of birds feeding in the garden has increased.Today there were 80+ Chaffinches in the garden and, at long last, a female BRAMBLING - my first in the garden this winter. The 10+ Blackbirds were also voraciously attacking any berries they could find or Sunflower hearts as an alternative (Roy Hargreaves)

Wintering BLACKCAP in Tring - BITTERN STILL

18 December: The BITTERN went to roost this afternoon at 4.12pm. I didn't see exactly where it flew up from but it went to roost in the same area as usual. Earlier I drew a blank in the gull roost at Wilstone. In my garden at Lakeside, Tring there has been a female BLACKCAP since last Saturday (Steve Rodwell)

Tuesday 22 December 2009

Sunday birding - 20 December - GREAT WHITE EGRET

Late morning I gave Warren Claydon a hand with the Webs count. There were no surprises and in fact the duck numbers were quite low. Only 3 Common Goldeneye at Wilstone and the female Red-crested Pochard was at Startop's End. The most interesting sighting was 6 Lesser Redpolls briefly by the carpark at Wilstone. I was determined to find a Med Gull at the gull roost this afternoon, but again Black-headed Gull numbers were relatively low compared to a week ago.

Fortunately I was saved from another blank by Dave Bilcock's call about the GREAT WHITE EGRET (flew across Marsworth Reservoir and landed very briefly in tree at Tringford before disappearing north). The bird never quite made it to Wilstone Reservoir, and I saw it briefly from the car quite high up doubling back to Marsworth along the stretch of road going to Wilstone cemetry. Remarkably the EURASIAN BITTERN put in a very late appearance for a number of observers, going to roost in reeds on the south bank of Marsworth Reservoir about 4.30pm (Steve Rodwell)

Monday 14 December 2009

BITTERN again tonight - worrying low number of roosting CORN BUNTINGS

SATURDAY 12 DECEMBER

WILSTONE RESERVOIR

Dave Bilcock, Roy Hargreaves and Mike Campbell all witnessed a flock of 6 adult WHOOPER SWANS on Wilstone early on Saturday morning. They flew in at 0830 hours and landed in front of the reedbed at the Cemetery Corner end, where they were photographed (DB) and settled for at least 15 minutes. I left home shortly after Dave texted me, but got caught up in a diversionary route, as the westbound A41 was closed.

By 0910 hours (when I arrived), the herd were nowhere to be found and had departed

Compensation came in the form of a pair of NORTHERN PINTAIL (roosting with 51 Shoveler on the Drayton Bank), 2 drake COMMON GOLDENEYE, the continuing BLACK-TAILED GODWIT and two COMMON REDSHANK and a juvenile Herring Gull.

There were just 5 Mute Swans present on Wilstone, along with 16 Great Crested Grebes and 2 Dabchicks.

STARTOP'S END RESERVOIR
(with Dave Bilcock)

9 Mute Swans (including a first-winter), 3 Great Crested Grebes, the female Red-crested Pochard from College Lake, 47 Shoveler (disturbed off Marsworth), 1 Wigeon, 11 Common Teal and 1 drake Pochard. A flock of 38 REDWING flew east.

COLLEGE LAKE BBOWT

19 Mute Swans (with 2 first-winters), 24 Gadwall, 42 Wigeon, 8 Shoveler and 15 Pochard.

Also noted were both Green and Great Spotted Woodpecker, 2 Song Thrushes, 4 Mistle Thrushes, Fieldfare, 40 Redwing, 4 Great Tits and 5 Wrens.

WESTON TURVILLE RESERVOIR
(complete winter bird survey)

Unusually, a good crop of wildfowl present, including 1 first-winter Mute Swan, pair of Gadwall, 15 Mallard, 25 Shoveler (17 drakes and 8 females - good count for the site) and 2 Tufted Ducks, as well as 8 Great Crested Grebes (high count), 15 Coot, 11 Moorhens, 37 Black-headed Gulls and 4 Common Gulls (including a first-winter).

Passerines included 1 Song Thrush, 14 Common Blackbird, Grey Wagtail, 10 Wren, 8 European Robins, 8 Long-tailed Tits and Great Spotted Woodpecker.

MONDAY 14 DECEMBER

Continuing cold (5 degrees C) but rather damp with light rain predominating during the afternoon.

WILSTONE RESERVOIR

At last - finally connected with the RUFFS !

The water level has risen even further, and has consequently become much more attractive to birds, with the entire site heaving with wildfowl and waders.

COMMON GULL (53+)

MARSWORTH RESERVOIR
(with Dave Bilcock; 1520-1615 hours)

The EURASIAN BITTERN flew from the SW corner at 1602 hours and went low below the line of the reeds before eventually landing high in the reedbed at the east end, close to the Grand Union Canal locks in Bucks. It then slowly made its way down in the reeds to sleep.

Most disconcerting was the fact that just 40 CORN BUNTINGS came in to roost. There were also 6 REED BUNTINGS.

The 14 Great Crested Grebes were still present - and 98 Shoveler feeding

Today's summary - Steve Rodwell

A very enjoyable afternoon with Don and Sandra Otter, Mike and Rose Collard and Mike Campbell, amongst others. The 2nd winter MEDITERRANEAN GULL was present in the Wilstone Gull roost as was the 'White' Back-headed Gull. There were also 2 RUFF (different than those photographed recently) and the BLACK-TAILED GODWIT was still present. The EURASIAN BITTERN was at Marsworth again, showing well on some flattened reed on the far bank about 4.10pm. Again it flew to roost in the Bucks sector. Sandra also saw some movement in the reeds not far from where the Bittern was roosting, and there may well be a second bird present. As we left 2 COMMON REDSHANKS called from Startops and earlier there was a female PINTAIL on this reservoir. Yesterday there were at least 2 Cetti's Warbler singing at Marsworth and one this evening.

BITTERN showing well




The EURASIAN BITTERN appeared at 1610 hours this evening and showed well (per Steve Rodwell)


MEDITTERANEAN GULL makes rare daytime visit to Marsworth Reservoir


This morning Steve Todwell found the second-winter MEDITERRANEAN GULL at Marsworth, which made a change from struggling to find it in the roost most evenings. Also enabled me to get a much better picture than the usual blurry roost shot (Dave Bilcock).

BITTERN is back

SATURDAY 12 DECEMBER: This evening the gull roost at Wilstone was quite disturbed from nearby shooting. One second winter MEDITERRANEAN GULL roosted that was seen by a number of observers. Together with Mike Campbell and Joan at Marsworth we tried for the EURASIAN BITTERN. About 10 minutes before it was dark, Mike picked it out on the opposite bank, standing at the front of the reedbed in full view. Just before dusk the Bittern flew and roosted in the Bucks section. At least 2 Cetti's Warblers singing and several Water Rails (per Steve Rodwell)

Saturday 12 December 2009

LITTLE EGRETS rise in number

Joan Thompson counted a record 26 LITTLE EGRETS flighting out from the 'new' Stocker's Lake roost early this morning. There were also 4 RED-CRESTED POCHARDS present.

Another Saturday morning - and another brief-staying rarity (or rarities in this case, with a flock of WHOOPERS)







A herd of 6 adult WHOOPER SWANS flew in to Wilstone Reservoir at 0830 hours this morning and remained for less than 20 minutes before flying off (Dave Bilcock, Roy Hargreaves and Mike Campbell only).
The BLACK-TAILED GODWIT was still present (photographed above - DB), along with the two adult COMMON REDSHANKS, 200+ European Golden Plovers and a fresh pair of NORTHERN PINTAILS roosting on the Drayton Bank.
The female Red-crested Pochard was on Startop's End Reservoir (DB, LGRE)

Thursday 10 December 2009

Med in roost

The adult winter MEDITERRANEAN GULL roosted on Wilstone this evening (Steve Rodwell)

Two RUFF early on but not later

THURSDAY 10 DECEMBER

A much colder day, with temperatures struggling to reach 7 degrees C. A beautiful day though, with clear blue skies, all day sunshine and a cold NE breeze. Once again, I found myself back at Wilstone, where Roy had discovered two RUFF early on, roosting on the remaining section of spit visible from the jetty. They were not be found however.

WILSTONE RESERVOIR
(Joan Thompson and Mike Campbell also checking)

Checked all of the available mud on Wilstone. The BLACK-TAILED GODWIT was still present close to the Drayton Bank Hide, there were two COMMON REDSHANKS in the same area, a total of 14 COMMON SNIPE, 225 Lapwing and 473+ EUROPEAN GOLDEN PLOVERS.

A female COMMON GOLDENEYE was in 'Boathouse Corner', the juvenile GREATER SCAUP was in the SW quadrant, with Great Crested Grebes still numbering 12. Otherwise, very much the same as yesterday.

STARTOP'S END RESERVOIR

Great Crested Grebes (2), Mute Swan (6 adults), Common Teal (1 drake), Shoveler (4), Tufted Duck (31), Pochard (1 drake), Moorhen (12) and Redwing (8 in Hawthorns by sharp bend).

MARSWORTH RESERVOIR

Reed-cutting for the Bitterns in progress and new rides being created. Little of note other than 14 Great Crested Grebes and an adult Mute Swan still. No Shoveler !

Wednesday 9 December 2009

No sign of yesterday's Ruff but a BLACK-TAILED GODWIT in replacement

WEDNESDAY 9 DECEMBER

A much milder day than of late, with temperatures reaching 9 degrees C. It was very misty and drizzly early on but this gave way to clearer conditions, with a slight SW breeze. It remained dry until darkness fell.

After it transpired that an adult RUFF had been present on Wilstone yesterday afternoon (photographed from the hide), I endeavoured to try and relocate it, and visited early afternoon.........

WILSTONE RESERVOIR, TRING
(1230-1350 hours)

The water level on Wilstone had increased dramatically, totally submerging much of the mud and vegetation exposed since July. This had attracted large numbers of dabbling duck back again, especially Teal and Mallard, as well as large numbers of Lapwing.

There was no sign of yesterday's Ruff but I did find a BLACK-TAILED GODWIT. The full list below....

Great Crested Grebe (12)
Little Grebe (4)
Continental Cormorant (15)
Mute Swan (just 6 adults remaining)

Three MEDITERRANEAN GULLS this evening

This evening with Dave, Charlie, Ian, Mike and Rose Collard, there were 3 MEDITERRANEAN GULLS in the roost, plus the 'white' B.h.Gull. The med gulls included 2 second winters and an adult. Unfortunately the first winter was playing hard to get and has failed to materialise the last 2 evenings (I have never seen the 3 different age groups together). The second winter that Dave saw just before it was dark is a very interesting bird. It was seen several weeks before and is quite difficult to pick out, as the primaries have an unusual amount of black on them. There was also one second-winter Herring Gull (Steve Rodwell)

Friday 4 December 2009

Another good Black-headed Gull roost




Both SMEW were still present late this afternoon, the male a real challenge to find as it was diving in amongst the roosting BHGs. The roost contained 2 MEDITERRANEAN GULLS (a new adult and the regular 1W) as well as the albinistic Black-headed Gull (pictured above) (Dave Bilcock).

SMEW bonus of colder weather













Redhead and drake SMEWS (Martin Parr)
FRIDAY 5 DECEMBER

Another overnight frost and a clear, bright, sunshine-filled day, with temperatures reaching a high of 6 degrees C. The raw westerly wind had dropped and had been replaced by a light SW, making it much more pleasant to bird than yesterday. Highlight of the day was the two SMEW that Roy Hargreaves found on his early morning walk round.

A drop in temperatures bring first SMEW of year

This morning the juvenile GREATER SCAUP was still on the lagoon to the right of the hide and a vociferous CETTI'S WARBLER was in the reed bed.

The undoubted highlight however was the pair of SMEW that I found. Initially I saw the redhead (presumed female), and phoned David Bilcock to alert him and ask him to put word out - it was quite cold this morning so I figured texting would take me even longer than normal with gloves on. After alerting David I then carried on checking the duck, and trying to relocate the Smew and when I refound it there was a drake with it. When I called David again he was a little concerned until I reassured him that it was only to let him know that there was also a second bird.

There was also a Green Sandpiper on the inlet to the left of the hide and a drake Common Goldeneye about. The water level also appears to be rising fairly quickly at the moment, but fortuntaely these Smew will not be able to swim into the bushes like the last one I found did.

Mike Campbell also texted me about a redhead GOOSANDER at 8:50, but I would think that this bird flew in after I had moved on from the jetty as I would be surprised if I had missed that (Roy Hargreaves)

December Counting





CORN BUNTINGS are back roosting for the winter in Marsworth Reedbed and Northern Shovelers galore are feeding there (pictures by kind courtesy of Mike Lawrence, one of the UK's foremost bird photographers)

THURSDAY 3 DECEMBER

A 12mph Westerly wind carried very cold conditions to our area today with temperatures struggling to just 5 degrees C. It remained dry but was extremely sodden underfoot, with heavy cloud cover.

I carried out my first December counts at the reservoirs - most pleasing was the return of roosting CORN BUNTINGS on Marsworth........

Very impressive this evening with no less than 3,289 birds in by dark, including the two regular MEDITERRANEAN GULLS (first and second-winter), the albinistic Black-headed Gull, 3,244 Black-headed Gulls in total, 37 COMMON GULLS (mostly adults) and 6 adult Lesser Black-backed Gulls pre-roost.

Tuesday 1 December 2009

REDSHANK flock drop in

At Wilstone this morning, the GREATER SCAUP was still on the lagoon to the right of the hide as was a male Common Goldeneye. I also saw four Lesser Redpoll, by the cress beds, that might be the same four I saw last week by Rushy Meadow. I also saw five Common Redshank land on the lagoon by the hide - although I was by the jetty at the time (Roy Hargreaves).

Saturday 28 November 2009

BARN OWL delight

Just seen a BARN OWL 2320 sitting on top of the left hand roadside hedge opposite Wilstone Reservoir shortly before the S bend approaching from Aylesbury direction
(Dave R Lee, Pitstone)

SCAUP still with us

This morning the juvenile GREATER SCAUP was in its new usual haunt on the lagoon to the right of the hide. Also a Little Egret flew into the creek to the right of
the hide. There was a Green Sandpiper in the inlet to the left of the hide and
40+ Meadow Pipits on the mud by the hide. Finally there were eight
Red-legged Partridges on the field south of the canal where I have seen Ring
Ouzels in the past (Roy Hargreaves).

Tuesday 24 November 2009

Poor weather continues

This morning the juvenile GREATER SCAUP was still on the lagoon to the right of the hide. There were also three Lesser Redpoll along the Dry Canal and Cetti's Warbler singing to the right of the hide.

Conditions were drizzly (so the light was poor), and breezy so a thorough search was not possible in the conditions and time that I had before work (Roy Hargreaves)

Partial albinistic Black-headed Gull at Pitstone







This morning (Sunday 22 November) the leucistic Black-headed gull was present roosting amongst the other gulls at Pitstone Quarry. This is a stunning bird as hopefully can be seen in the pictures above. When it is in flight it can be readily picked out as its upper wing is pure white except for black tips to the outer primaries. Last weekend myself and Steve saw it in the roost at Wisltone and I've also seen it at Startops.

Otherwise the juvenile GREATER SCAUP was still at Wilstone and a GREEN SANDPIPER at Tringford (Dave Bilcock).

Saturday 21 November 2009

COMMON CROSSBILLS at Ringshall

A flock of 10 COMMON CROSSBILLS was seen in Ringshall this morning (Don Otter)

MED GULL in roost

A first-winter MEDITERRANEAN GULL was in the roost (Dave Bilcock) whilst the juvenile GREATER SCAUP and 6 Common Snipe were still present (Jeff Bailey)

Tuesday 17 November 2009

GREATER SCAUP still present

The juvenile GREATER SCAUP was present on the lagoon to the right of the hide - although it was actually straight out.

A Siskin also flew over this morning. There are also still good number of Meadow Pipits and Pied Wagtails on the mud.

The water level, having risen 40mm over the weekend, has dropped back about 20mm (figures from the BWB employee). They are still pumping water out to maintain the canal level and apparently they have taken a large amount out of Tringford so this might be where the Green Sandpipers have moved to (Roy Hargreaves)

BLACK-NECKED GREBE finally makes it on to annual list



SATURDAY 14 NOVEMBER

A very deep area of low pressure passed over the area today bringing near gale force SSW winds and more heavy rain, occasionally torrential. There was little respite from the conditions all day and mid afternoon saw the arrival of a windswept juvenile GREAT NORTHERN DIVER at Calvert BBOWT

TRING RESERVOIRS

David Bilcock discovered an adult winter BLACK-NECKED GREBE early morning, the first record there this year. I rolled up at Wilstone at 1045 hours and dodging the heavy showers and braving the gusty wind, managed to relocate the bird, diving frequently just offshore of the central bund. It was sheltering from the wind in the small bay just east of the Drayton Bank but later moved much closer to the jetty and was still present when I left early afternoon. Roy, Mike Campbell and Charlie Jackson had all seen it before I arrived.

The Week so far

Despite the fog in the mornings it hasn't been too bad at Wilstone.

The juvenile GREATER SCAUP has been in the inlet by the hide the past two mornings. There are still good numbers of European Golden Plover on the spit and about 40 Pied Wagtails and 40 Meadow Pipits on the various mud banks. A single Siskin was by the hide yesterday.

Yesterday four Chinese Water Deer were on the mud to the right of the hide and there was a Red Fox this morning.

The water level has risen slightly as the lower water level post now has water around its base (Roy Hargreaves).

Steps Hill WOODCOCK

Flushed a WOODCOCK this afternoon near the bottom end of Incombe Hole, on the path going up from near the B488/489 junction at Ivinghoe, just before where the tree-lined path opens out into the first field at the end of the gardens. Also one or two Buzzards, Common Gull, Fieldfares (Dave R Lee, Pitstone)

Weekend Gull Roosts


Saturday with Steve, Warren and Roy a 2W MEDITERRANEAN GULL was present

Sunday with Steve and Mike Campbell the below adult YELLOW-LEGGED GULL roosted (Dave Bilcock)

GOOSANDER at College Lake 8/11

Wilstone: GREATER SCAUP still present, today it was close to the Drayton Bank opposite the new overflow. On the central spit a single Dunlin was amongst the Golden Plovers and CUA carbo roosting.

College Lake: Paul has just found a GOOSANDER on the marsh, a drake moulting out of eclipse, which promptly swam behind a clump of willows and disappeared. No doubt still present but roosting out of view.

MED GULL

Steve Rodwell observed a first-winter MEDITERRANEAN GULL in the Wilstone Reservoir roost this evening - roosting amongst 700 or more Black-headed Gulls. At least 1 DUNLIN was also still present.

First day of November pretty much a washout

NOVEMBER 2009

SUNDAY 1 NOVEMBER

Heavy rain persisted throughout the morning along with blustery WNW winds making birding conditions very unpleasant. It finally cleared early morning with brighter conditions following, although the wind still remained strong. Temperatures struggled to 15 degrees C. Despite an excellent Saturday where rare wildfowl was the main theme and a dapper male Black Redstart attracted the crowds, Sunday was largely a let down for me.

STARTOP'S END RESERVOIR, TRING

There was no sign of Saturday's Common Goldeneye but overnight rain had pushed water levels up attracting large numbers of dabblers to the SW shore - including 6 Mute Swans, 10 Greylag Geese, 143 Mallard, 15 Shoveler and 37 Common Teal whilst the open water held 4 Great Crested Grebes, a pair of Gadwall, 43 Tufted Ducks and an impressive 86 Northern Pochards.

TRINGFORD RESERVOIR

Sadly, the road running alongside the reservoir harboured a fresh Badger casualty.

Few birds on Tringford - just 3 Great Crested Grebes, 5 Grey Herons, 1 Mute Swan, 2 Common Teal, 8 Gadwall and 6 Northern Pochard.

WILSTONE RESERVOIR

Totally windswept - 3 DUNLIN from the Drayton Bank Hide being the highlight, with the juvenile GREATER SCAUP still feeding on the east shore.

LONG MARSTON (HERTFORDSHIRE)

No sign of yesterday's adult male Black Redstart enjoyed and photographed by many (see blog)

WINGRAVE AREA (BUCKS)

Two adult Moorhens on the village pond at SP 870 192 with 41 Linnets just north of Lower Windmill Hill Farm at SP 872 184.

GROVEBURY SAND QUARRY (BEDFORDSHIRE)

Just outside the Tring Recording Area, 6 DARK-BELLIED BRENT GEESE were present until at least 0945 hours in driving rain (Johnny Lynch). They were not there when I visited mid afternoon.

TONGWELL LAKE, MILTON KEYNES (NORTH BUCKS)

The pair of GREATER SCAUP were showing very well diving frequently in front of the main island at Tongwell Lake at SP 867 423. Both birds were adults with the drake just moulting out of eclipse with patchy grey in the flanks, light grey vermiculations on the mantle, a black breast, a rich dark green sheen to the head and a pale blue bill with a dark nail restricted to the tip. The adult female had an extensive white blaze, extending on the forehead as well as at the sides of the bill, a similarly patterned bill, flat and broad dark brown head and breast and dark grey vermiculations on the sides, flanks and mantle.

Saturday 31 October 2009




This superb adult male BLACK REDSTART (photographed by both Dave Bilcock and Chaz Jackson above) was discovered in Long Marston village by Johne Taylor this morning and remained near the church in the vicinity of 17, The Bromley, throughout the rest of the day.

Early morning in the rain

Wilstone: Very wet but GREATER SCAUP was still present and a single DUNLIN amongst the large flock of Lapwings from the hide.

Startop's End: 2 COMMON GOLDENEYES and a leuistic BHG on the mud with the other gulls (snowy white, with milky tea coloured primaries) (Dave Bilcock).

ATLANTIC GREAT CORMORANTS wintering at Tring


Both the Forvie colour-ringed ATLANTIC GREAT CORMORANTS have now returned for another winter at Tring. This morning CUA was roosting in front of the hide at Tringford (see picture above). This is the FIFTH winter it has returned, first appearing as a juvenile in December 2005 and every winter subsequently.

Also DXA was still at Wilstone this morning roosting on the exposed bar opposite the jetty. This bird first appeared at Ting in November 2007.

Both these birds return back to Forvie each summer, and have been recorded at the Ythan Estuary.

If you see these birds locally, or better a different bird with a white darvic on its left leg with black 3 letter code, could you pass on the details to Raymond Duncan who coordinates the ringing project raymond@waxwing.fsnet.co.uk. (Dave Bilcock)

SCAUP images




Local birder Martin Parr obtained these excellent images of the Wilstone GREATER SCAUP this afternoon - note how the grey fearhers are now coming through on the mantle and sides

Two Med Gulls in roost

Two MEDITERRANEAN GULLS were in the Wilstone roost tonight, an adult with a noticeably greyish head (still moulting into winter plumage) and a first-winter bird. Probably over 700 Black-headed Gulls at 4.45pm. The adult then flew off with several hundred gulls, before returning just before 5.00pm and the first-winter came in about 4.50-4.55pm. The Black-heads were very unsettled and almost all of the birds headed off just before it was too dark to see (Steve Rodwell)

GREATER SCAUP still present

FRIDAY 30 OCTOBER

Wind in the Southwest, still very mild, dry but mainly overcast. After seeing a fair bit of Woodpigeon passage today, checked out the Hills but it was a waste of time - virtually nothing to be found and almost birdless. Just the odd Chaffinch moving.

STARTOP'S END

Checked out the resident HOUSE SPARROW population and was pleased to find 15 roosting in the large conifer on the corner of Watery Lane, attracted in to the cage harbouring the Queleas and Cockatiels at the back of the Angler's Retreat garden.

WILSTONE RESERVOIR

Nothing new. The juvenile/first-winter GREATER SCAUP was still showing very well, feeding just north of the jetty and in amongst the feeding Canada Geese. As Jason commented, moulting in quite a few new grey feathers now.

Wildfowl also included 43 Gadwall, 3 NORTHERN PINTAIL (2 adult drakes), 159 Shoveler and 28 Mute Swans (7 first-winters) as well as just 4 COMMON SNIPE, 119 EUROPEAN GOLDEN PLOVER and 2 adult COMMON GULLS

Big rise in COMMON SNIPE numbers

This morning a CETTI'S WARBLER was singing in the cressbed bushes. A Green Sandpiper in the bay by the hide, 14 Common Snipe around, 40 Meadow Pipits on the mud banks by the hide and the juvenile GREATER SCAUP close to the jetty - it really does come in close to the bank at times.

I also had a group of Bullfinch fly over, but I was under trees and couldn't see them (Roy Hargreaves)

Major thrust in CHAFFINCH passage










WEDNESDAY 28 OCTOBER

Another day with little wind at first but increasing southerly and SSW later, with intermittent drizzle and continuing warm temperatures (18 degrees C). I spent much of the morning on the hills but was disappointed with general passage, the main thrust of birds moving well to the east of the Ivinghoe complex. There were good numbers of thrushes - but not the numbers I expected - but exceptional numbers of Chaffinch. Some kind soul had strategically placed some apples in the 'Ring Ouzel clump'.

DOWN FARM/PITSTONE HILL FIELDS

There are two fields which are harbouring large numbers of wintering farmland birds at the moment - the large ploughed field immediately south of the Ridgeway at SP 955 145 and the stubble field to the west at SP 953 145. I keep plodding away at them in the hope of locating a Twite, Richard's Pipit or Lapland Bunting but alas, again today, no sign of any of these vagrants. Good numbers of common birds though -:

Woodpigeon (322 - all local birds)
Stock Dove (19 in with the Woodpigeons)
Eurasian Skylarks (42)
Meadow Pipits (28)
COMMON STONECHAT (a male frequenting the fenceline at the north end, by Grim's Ditch footpath, by SP 952 145 - present for at least a week)

CROSSBILLS still in the forest

My best views for a long time of COMMON CROSSBILLS this morning,19 of them sitting in a bare Field Maple at Chivery Hall Farm, Bucks.They flew off back towards Wendover Woods (per John)

Continuing GREATER SCAUP, DUNLIN, PINTAIL and LITTLE EGRET

MONDAY 26 OCTOBER

Whenever the clocks go back, I always sense a feeling of sadness and cannot help feeling that the autumn migration is nearly over. I harp back to the sounds and sights of late summer and think back to my last Common Swifts in my village at the end of August - another year is once again coming towards a close.

Today, it really did still feel like summer. It was surprisingly warm (with temperatures reaching 16 degrees C by midday) with clear, calm and sunny conditions and a fresh southerly wind.

There was no sign of the Osprey in the Chess Valley this morning so I moved south to explore a 'new' site for me - 'Hogback Wood' between Forty Green and Beaconsfield.

Quiet start to new week following the clock change

Monday morning - very quiet for passage on the Ivinghoe hills this morning, hardly surprising given the wind direction and strength yesterday. Four CORN BUNTING went over before dawn and there was a BRAMBLING in with Chaffinches in the Beech trees between the main car park and the 'S' bend.

I then moved onto Wilstone Res where the juvenile GREATER SCAUP and partial albino Coot were still present near to the jetty but on the side towards the car park (Mike Wallen)

College Lake 25/10

Wildfowl numbers are finally starting to build up with around 150 Wigeon, 80 Pochard, 60 Tufted Duck, 13 Mandarin and single figures of Shoveler,and Gadwall. The female Red-crested Pochard was still present and still good numbers (for here) of Mute Swans at 48 including 3 juveniles. Four Common Snipe is the best I have managed so far this Autumn.

Juvenile Peregrine, Buzzard and 3 Red Kites flew over during the day (Paul)

Gull Roost 25/10


This evening was the first the gulls remained to roost at Wilstone. Approximately 600 Black-headeds were present and in addition to the above first-winter MEDITERRANEAN GULL Steve Rodwell found, 2 Common gulls and one Lesser Black-backed Gull were also present (Dave Bilcock)

Sunday 25 October 2009

Migrant COMMON CROSSBILLS

Another great morning, not for quantity but for quality, enjoyed with David Bilcock.

Highlight was only my third ever record there of COMMON CROSSBILL when a flock of 14-18 flew over us , 5 minutes before sunrise.

A first winter RING OUZEL flew across in front of us and up onto Ivinghoe Beacon where it landed in a clump of bushes at the East end but was not seen again.

Otherwise pretty typical late October fare with a few Thrushes and Finches over, and a COMMON STONECHAT near the 'S' bend (Mike Wallen)

Roosting MEDITERRANEAN GULL















There is a first-winter MEDITERRANEAN GULL in the Wilstone Reservoir roost this evening (found by Steve Rodwell), whilst the juvenile GREATER SCAUP is still present (new images above taken by Chaz Jackson).

Charlie also photographed the piebald Coot

Saturday 24 October 2009

ATLANTIC GREAT CORMORANT returns















The juvenile GREATER SCAUP was still present at Wilstone this morning (new image attained above) as well as the Aytha hybrid (see two images). Also amongst the roosting cormorants was one of the returning colour-ringed ATLANTIC (carbo) birds from the Sands of Forvie in Aberdeenshire, coded DXA. I think this is its 3rd year it has wintered around Tring (David Bilcock).





Wednesday 21 October 2009

Another RING OUZEL

I finally had a day off today so although not on the hills for dawn, I covered them more extensively than of late. It was pretty much typical Autumn fayre but with a noteable number of Song Thrush on the hills.Whilst walking up the beacon I accidently flushed a RING OUZEL which must have been perched up in one of the small bushes on the South-eastern slope, it flew away from me and up and over to the North side of the beacon. It was clearly different to the stunning male in the area on Monday. It flushed from about 150 metres, and I suspect it newly arrived last night. It appeared to drop into the bushes just down from the kissing gate which is 300 metres East of the trig point; this is an area that has regularly held them in previous Autumns.

Highlight however was my second obvious continental Song Thrush in three days. This bird was in the top scrub over the road from the car park, it was one of a pair, the other looker paler and slightly greyer than 'ours' but the obvious continental was superb. It was really grey and white, just like the bird of a couple of days ago and whilst it could be argued that many of ( if not all ) the migrants on/ over Steps in Autumn are from the continent there is no doubt in my mind with these grey birds. I have only seen three birds like this in Bucks, one at the rear of my garden a few years back and these two in the last few days. This 'cline' in Song Thrush reminds me a bit of chiffchaff with grey ones further East.

A quick look at Startops produced nothing of note. At Wilstone the highlight was the juvenile GREATER SCAUP still present near the jetty and the North shore. No Rock Pipits but up to 20 Mipits were commuting between the Northern bank/ jetty area and the field behind. Other birds of note were 2 Pintail and c120 Golden Plover (Mike Wallen)

SCAUP

The juvenile GREATER SCAUP is still present on Wilstone Reservoir

Aythya Hybrid on Wilstone







This drake Northern Pochard hybrid was also present on Wilstone today roosting with Pochard on the central spit. In recent days it has been at Calvert BBOWT (Bucks) where Tim Watts obtained these excellent images (Lee Evans)

SCAUP surprise





















MONDAY 19 OCTOBER

The wind veered SE this morning, the first time in a long while, with the raw and freshening breeze continuing throughout the day. It brought in low cloud and intermittent drizzle and saw a light fall on the hills.

IVINGHOE HILLS NR (BUCKS)
(1200-1400 hours)

Pride of place went to a stunning male RING OUZEL and unlike all of the previous individuals at Ivinghoe this autumn, was actually 'settled' and 'twitchable'. Mike Wallen had discovered it first thing and had very kindly placed details on the local email group; Mike Campbell had searched but failed to find it. I arrived at midday and relocated it after about fifteen minutes but it had moved. It was showing extremely well, feasting on Hawthorn berries, in the cluster of bushes and scrub just 100 yards NE of the S-Bend at SP 961 164 and could be easily 'scoped from the main footpath leading up to the Beacon looking over to the right (east). It was very vocal, 'chacking' frequently, particularly when in flight, and was a well-marked individual albeit quite scaly. It had a well-defined white breast-band.

This same clump of bushes had also seen landfall of a good number of 'migrant thrushes' with 10 or more CONTINENTAL SONG THRUSHES and 7 dark-billed CONTINENTAL BLACKBIRDS. I was surprised though at the lack of REDWINGS - just one flock of 68 birds passing over high to the south over Coombe Wood.

There was little sign of much other migration apart from the constant diurnal passage of low-flying, mostly singleton Chaffinch - a total of 27 passing to the west in the two hours I was present.

A MARSH TIT was unusual in scrub below the main car park, whilst Jays were again much in evidence (12+ flying to and fro gathering acorns) and 4 COAL TITS were together in the main wood above Incombe Valley.

A single Yellowhammer passed over, 14 Meadow Pipits and two local Great Tits. Top Scrub was particularly uninspiring with yet again not a single warbler in sight - and no thrushes either.

WILSTONE RESERVOIR
(1415-1600 hours)

Wilstone Reservoir is now at the lowest I have ever seen it with the mud in the SW quadrant the most expansive on record and the water in that sector in great danger of drying up completely. There was little evidence of any new arrivals and in fact, the large European Golden Plover flock of recent weeks had disappeared. I undertook a complete inventory of the site and in doing so located a juvenile GREATER SCAUP. However, I couldn't believe myself on this one, firstly because I had previously written it off and secondly because of all of the current controversy surrounding the Marlow flock (see images of putative Greater and Lesser Scaups on Uploaded Images Files on Bucks Bird Club Website). I did not dare put it out, following my comments reference the Marlow birds, and summonsed a second opinion from Mike Campbell and Joan Thompson (both observers I knew would be close at hand and without commitment). Mike of course came armed with his video camera and took a lengthy piece of film (watch his highlighted edits at http://www.flickr.com/photos/16605076@N05/) and I also contacted David Bilcock who I can always rely on to get something of a good record shot at least (see his images above as well as two stills from Mike's video sequence). I was totally convinced that the bird was a juvenile Greater Scaup but found the circumstances barely conceivable after events of the previous 24 hours.

Anyway, here's the documentation:

GREATER SCAUP (juvenile)
I discovered a juvenile whilst click-counting the Coot flock just after 1420 hours. It was showing extremely well in the extreme NE end of the reservoir and was feeding alone but in close accompaniment of the Coot. It was occasionally joined by the odd drake Tufted Duck and male and female Northern Pochard and was slightly larger than Tufted Duck but with a noticeably wider and more spatulate-shaped bill, dark grey in colour with the dark nail restricted to the tip. The head was large and rounded and the neck long with no hint whatsoever of any tuft at the rear of the crown, with a clearly evident pale crescentic area of pale feathers around the ear-covert area (extending down to the lower part of the face) and buffish-white extensive patches at either side of the base of the bill (but significantly not forming a thick blaze over the top of the bill on the forehead). It was also much warmer (paler brown) in body colouration (than female Tufted Duck), with warm brown sides but a dark brown head and neck. When roll-preening, its belly and under-carriage was seen to be gleaming white. It had a very dull brownish-yellow eye, typical of juvenile Aythyas, and obvious grey legs when preening. The mantle was very dark brown but interspersed with a few new grey vermiculated feathers, several of these also bearing through on the fore-flanks as well as on the scapulars. In flight, the wing was seen to be broader than Tufted Duck but very similar in pattern, with a striking white bar across the secondaries and primaries petering out to grey in the outermost two primaries. It had a very unique diving ritual too - leaping right out of the water when diving - quite unlike that of the technique preferred by Tufted Ducks
