In what largely felt like a typical December week, where the odd lingering rarity and a couple of treats of the Anser persuasion provoked the most interest, it was Glamorgan which provided the greatest prize. A juvenile Pacific Diver was an excellent find at the private Eglwys Nunydd Reservoir from 11th, the site of a famous Bobolink record back in 2010. It is just the second for Wales after one at Llys-y-Fran Reservoir, Pembrokeshire, between 2007 and 2009 – itself the second British record at the time. Elsewhere, the returning adult was again off Crookhaven, Co Cork.
Since its addition to the British list in 2016 on the basis of a 40-year-old record from Lancashire, Cackling Goose has been a rare bird south of the Scottish border – individuals in Cumbria and Northumberland the only such examples – making one with Pink-footed Geese at Ribble Marshes, Lancashire, from 9th very popular indeed. Another new bird accompanied Barnacle Geese and a white-morph Snow Goose at Ballygilgan, Co Sligo, early in the week, with at least one lingering on Islay, Argyll.
Just south-west of Glasgow, the white-morph Ross's Goose continued to attract a healthy number of admirers at Hunterston Sands, Ayrshire, where it remained settled throughout.
Lancashire's elusive Belted Kingfisher continued to be tricky to pin down, reported along the River Darwen near Roach Bridge on 6th before a likely fly-past sighting along the River Ribble near Red Scar Wood the following day.
Several Lesser Scaup included new drakes at Lough Neagh, Co Armagh, and Ballinascarty, Co Cork, with others still at Loch Skerrols, Islay, Argyll (four), Beesands Ley, Devon (two), Round Lough, Co Cavan, and Ardmore, South Uist, Outer Hebrides. Drake Ferruginous Duck remained at both Thorpe Park, Surrey, and Blashford Lakes, Hampshire, with at least one King Eider still at Uyeasound, Unst, Shetland, and the drake White-winged Scoter still at Musselburgh, Lothian.
Last noted at Seahouses, Northumberland, on 14 November, the young female Walrus, christened 'Freya' during her Dutch escapades, continued her journey northwards with a stop at salmon cages near Vementry, Mainland Shetland, from 10th. Shetland also hosted a Parti-coloured Bat – at Vidlin, Mainland, on 11th, while a Pygmy Sperm Whale was unfortunately found dead at Burton Bradstock on 9th.
Hoopoe isn't an expected species to see during a cold Scottish winter, so two this week – at Kingoodie, Perth & Kinross, and Montrose, Angus – were somewhat of a surprise. Auchinleck, Ayrshire, scored a notable inland Pallas's Warbler on 12th, a Great Grey Shrike was at Glen Feshie, Highland, and the Cetti's Warbler remained near Stevenston, Ayrshire. Broadford on the Isle of Skye hosted a Siberian Chiffchaff and a probable Rough-legged Buzzard was reported at Glasdrum Wood NNR, Argyll, on 11th.

An impressive couple of days for Balgray Reservoir, Clyde, included a Velvet Scoter, Great Northern Diver and Greenland White-fronted Goose.
Four Ring-necked Duck on Tiree, Argyll, included a new drake, with a Todd's Canada Goose at Cornaigbeg and a Siberian Chiffchaff at Balephuil. A Great Egret at Eorrabus was the best on Islay.
At least one Humpback Whale continued to be seen daily off Pettycur, Fife.
Northern Isles and the Hebrides
The regular White-billed Diver remained at South Nesting Bay, Mainland. The young drake Ring-necked Duck was still at Loch of Tingwall, Mainland, with the Todd's Canada Goose relocating to Vatsetter, Yell, on 12th, and a lone Tundra Bean Goose was at Fleck, Mainland. Little Auks had a fair showing: five sites scored, including 397 past Sumburgh Head in less than three hours on 9th. Iceland Gulls were at just two sites and Glaucous Gulls at three, including four juveniles on Fair Isle on 6th, where the Red-necked Grebe continued.
A juvenile Surf Scoter was off the south end of Westray on 7th, with a Grey Phalarope off Papa Westray on 11-12th. The first-winter European Turtle Dove was again at Orphir Bay, Mainland, while a Common Rosefinch was trapped and ringed at Finstown. Just one Iceland Gull made the Orkney airwaves, with one off Burwick, South Ronaldsay, on 8th, and at least one adult Glaucous Gull roamed Papa Westray.

The European Serin remained at Brusselton Wood, Durham, throughout, where a Hawfinch overflew on 11th. A few Little Auks continued to pass Whitburn Coastal Park in the first half of the week and single Iceland and Glaucous Gulls also passed the site. Hurworth Burn Reservoir produced a late Garganey on 10th and South Shields scored an Iceland Gull and 16 Snow Buntings. A Rough-legged Buzzard was reported by the A1 at Darlington on 6th.
In Cleveland, Black-throated Divers were at Seal Sands and Hartlepool, with the latter locality also producing a Glaucous Gull and a couple of Velvet Scoter. Little Auks were seen off a couple of sites and Snow Buntings were noted in small numbers. A Lapland Bunting was recorded at Saltholme RSPB on 10th and a possible Rough-legged Buzzard flew over Hartlepool Headland that morning.
The drake Green-winged Teal continued at Conder Green, Lancashire, and it transpired that a second drake had been present on 27 November. A Tundra Bean Goose was with Pink-feet at Ryscar Farm, Carleton, and Snow Buntings were scattered at a handful of coastal localities, while a Great Skua at Brockholes LWT on 11th was the second site record.

A probable Great Northern Diver overflew Cae Howel, Shropshire, on 11th.
In Worcestershire, a Grey Phalarope passed through Westwood Pool and a Siberian Chiffchaff was at Kempsey sewage works. Draycote Water, Warwickshire, logged two Great Northern Divers on 10th, with one lingering until at least 12th, when a Glaucous Gull was picked out among the throng of roosting gulls.

A single Greater Scaup was at Swithland Reservoir and a juvenile Iceland Gull flew over Shawell on 11th.
East of England
In Norfolk, the Barred Warbler lasted out a mild week at Wiveton, while the Black Brant and Iceland Gull were still at nearby Cley. A Grey Phalarope flew past Weybourne on 10th, while the Great Grey Shrike continued at Waxham. In a winter where the species is scarce, two Tundra Bean Geese at Great Bircham on 12th were notable.

Well inland in a poorly birded part of Sussex, a Little Bunting at Iping Common from 11th was a first-class find and makes one wonder how often this species winters unnoticed in England in habitat mimicking its taiga breeding grounds. During the last three years there have been more Little Buntings in Sussex than Smew – a reflection of the duck’s rapidly changing status in the South-East – so a redhead at Ashburnham Forge was popular from 8-11th. A Shore Lark was at Pevensey on 10th. It seems the Arun Valley will host wintering Bewick’s Swans for at least another winter, with two at Pulborough 11th soon relocating the Burpham; 18 were at Scotney GPs on 9th, too. Church Norton and Goring-by-Sea scored Snow Buntings, the Polegate Hooded Crow was still about and Siberian Chiffchaffs were at Chichester GPs and North Chailey.
An adult Iceland Gull at Weston on 6th was probably the highlight of a quiet week in Hampshire, where Siberian Chiffchaffs were at Blashford Lakes and Eastleigh SF.

Slimbridge was the place to be in Gloucestershire with 51 Bewick's Swans, Eurasian Spoonbill, Little Stint, Western Cattle Egrets and a couple of Dark-bellied Brent Geese all reported. Eleven Hawfinches were at Parkend on 11th and the male Black Redstart remained at Sharpness.
In Wiltshire, a Siberian Chiffchaff was discovered at Westbury's sewage works on 9th. The Great Northern Diver at Cotswold Water Park and Snow Bunting at Mere both remained in place and 27 Hawfinches were recorded at Franchises Lodge RSPB. A released White-tailed Eagle was seen over two localities.
