This is my summary of records of rare birds from the UK in September 2017, this is not aimed at being a comprehensive account of all the rare's in the UK in this month, for such accounts see the Birdguides review of the week or the Rare Bird Alert weekly round-up. I am largely writing this as a personal record of rarity records to aid my knowledge and feed my interest in UK birds. The dates provided under each species are only the date of the finding of that bird, 'megas' are shown in red and a full date range for these species is shown. I have only included confirmed records and not included possibles or probables. The photographs that I used have been gleaned from the internet, I aim to provide the photographer with full credit and a link to their website or blog, if you see that one of yours has been used and you object to this then please email me and I will remove it immediately, alternatively if you would like to supply a better image or additional information or links then I will add.

NEARCTIC SPECIES
There was a remarkable arrival of American waders in the first two weeks of September, most noticably a good run of Semipalmated Sandpiper from 3rd September with at least four being found in Ireland on that day. This arrival was associated with a complex weather system with a stream of westerlies extending across the Atlantic. As this weather system wriggled its way westwards it produced a stunning American Redstart on Barra which continued to perform in the churchyard until 17th September.

A further low pressure system sweeping across the UK over the 10th and 11th produced a further arrival of rare waders and the remarkable double arrival of a Least Sandpiper (9th) and Stilt Sandpiper (11th) at Lodmoor, Dorset.

Semipalmated Plover
Keel, Achill Island, County Mayo - 13th-29th September
There are four accepted records of Semipalmated Plover in Great Britain and two from Ireland. Records are from March and April and September and October and are widely spread with birds recorded on the Isles of Scilly, Devon, Chichester and Hampshire (the same bird) and South Uist. Irish records are from County's Donegal and Kerry. Undoubtedly this species occurs more frequently than is know due to its similarity to Common Ringed Plover.
Upland Sandpiper
Fetlar, Shetland - 30th September when it showed well but there was no sign of the bird on 1st October.
There are 45 accepted records of Upland Sandpiper in Great Britain and 12 from Ireland. Records are from April, May, July, September, October, November and December with the peak month being October with 30 records. The species has occurred widely in the UK with six records from Shetland and 15 from the Isles of Scilly being the best locations. The highest total for a mainland county is of nine records from Cornwall. The last 'twitchable' records are from 2011 where a bird spent 16 days at Termoncarragh, Mullet Peninsula, County Mayo from 12th to 27th October and on the Isles of Scilly a bird was at Maypole, St. Mary's from 8th to 27th October, a stay of 20 days.

Black-billed Cuckoo
Dale of Walls, Mainland, Shetland - 18th September. Read the finders account on Birdguides here.
There are 14 British Records and 1 Irish record of this species with most birds being Autumn records extending from 23rd September to 8th November so this is a comparitively early bird. Most birds are one or two day stayers and are moribund or found dead. The one exception to this, which has not yet been accepted, was a bird from 22nd May to 1st June at Bayhead, North Uist. The Dale of Walls birds on 18th September proved to be a typical record and could not be located the following day.
Fantastic shot of the Black-billed Cuckoo by G W Petrie. Interesting to see this bird in Japanese Knotweed!
Porthgwarra, Cornwall - 24th September
St. Agnes, Isles of Scilly - 24th September
This is the westerly airflow and associated low pressure system located over the west of the British Isles that resulted in this double arrival of Red-eyed Vireo on 24th September (image from www.windy.com).
Buff-bellied Pipit
Tawin, Galway - 12th September
Rose-breasted Grosbeak
St. Agnes, Isles of Scilly - 29th September and into October. Read the finders account on Birdguides here.
There are 26 accepted records of the species in Great Britain and eight from Ireland. Records are from May, September, October, November and December with the peak month being October with 29 records. The prime location for Rose-breasted Grosbeak is the Isles of Scilly with 13 records from the Islands. The last switchable bird was a first-winter male that came to feeders in Hugh Town, Isles of Scilly from 18th-29th December 2012.
This deep low pressure appears to have resulted in the arrival of the Rose-breasted Grosbeak. From this position the low tracked northwards along the west coast of the British Isles.

PALEARCTIC SPECIES
With the seemingly constant flow of low pressure systems arriving from the Atlantic and with pretty much consistent westerly winds it was difficult to see how any eastern species might have arrived. Yet, as a low pressure passed through the UK over the 8th and 9th the top edge produced an easterly airflow from deep into Scandinavia and back to the northern islands sufficient to provide an arrival of at least five Arctic Warbler, a Great Snipe and a Lanceolated Warbler, mainly from Shetland but Sandwich Bay in Kent scored with a Arctic Warbler trapped and ringed at Sandwich Bay on 10th September.On 16th September low pressure systems were blocked from reaching our shores by the Azores high which extended north at least as far as Iceland. Low pressure systems were squeezed north meaning a temporary end to the arrival of American birds. At the same time a high pressure system was established over the Caspian and western Russia resulting in easterly winds reaching our shores. This resulted in a small arrival of eastern species such as Barred Warbler, Red-throated Pipit, Yellow-browed Warbler, Greenish Warbler and three Arctic Warbler, Western Bonelli's Warbler and a Rustic Bunting. The star bird on the 17th was a Pallas's Grasshopper Warbler that showed well at Burnham Overy Dunes on 17th.
On the 19th a low pressure system, that had passed through the UK, briefly settled to the east of the Baltic, this sent easterly winds off its northern edge resulting in the arrival of two megas, a female Siberian Thrush on Unst and a juvenile Yellow-breasted Bunting on Out Skerries. These eastern megas just two days after a Black-billed Cuckoo on Mainland Shetland.
Fair Isle, Shetland - 11th September
Eurasian Scops Owl
Ryhope, Durham - 27th September and into October. Read the finders account on Birdguides here.
There are 84 accepted records of Eurasian Scops Owl in Great Britain and 14 from Ireland. Records extend across all months with the exception of February and December with the peak months being April, May and June. The prime location for the species is Orkney with 14 records, this is perhaps somewhat surprising given the southern origin of the species, perhaps, it is simply easier to find a small owl on Orkney where there are few trees, or perhaps this indicates that the individuals occurring here are from the eastern parts of the range but why have there been no records from Shetland?

Arctic Warbler
While researching this Eurasian Scops Owl record I came across Stewart Sexton's blog, Stewchat, he has some fantastic photographs, field sketch's and watercolours of his birding and wildlife experiences. His notes and illustrations of the Scops Owl are exceptional. Have a look at Stewart's blog here: http://boulmerbirder.blogspot.co.uk. This is his Scops Owl, I am very envious of his talent:

House, Out Skerries - 20th - 22nd September. Read the finders account on Birdguides here.
There are some 237 British records of Yellow-breasted Bunting, however, since the early 2000's this species has undergone a rapid decline in the UK. This is linked to a decline of 90% and a retraction of its range by 5000 km since 1980 mainly due to an unsustainable trade in the species for as a prized cage bird, see article here.

SEABIRDS
With an almost constant flow of low pressure systems it was unsurpring that seawatching produced some exitement with the now annual records of Fea's Petrel but also a run of Barolo Shearwater from Cornwall on 4th and 5th.

Leach's Petrel
Strong winds overnight on 10th September produced a strong passage of Leach's Petrel on the 11th mainly in the west with 60 past Hoylake, Cheshire. Relocating birds were recorded widely on 12th with birds being seen as far up the the River Severn as Fretherne. Storm Aileen produced another flush of records on 12th. While on 13th 51 flew past Hoylake and 60+ past New Brighton both in Cheshire and on 14th a further 70 flew past Hilbre Island, Chesire. During this period there were numerous birds scattered around the country but it was the Wirral that held the lions share - a classic site for the species in certain weather conditions, mainly fast moving Atlantic depressions and stron NW winds.
One of the most amazing images of Leach's Petrel I have seen - ever! By Richard Steel, more of his fantastic images can be seen on his blog here: http://wildlifephotographic.blogspot.com/
New Brighton, September 11th
Synoptic chart from 18:00 11th September 2017 from magicseaweed showing the first major storm of the Autumn, Storm Aileen producing gusts of up to 75mph - the storm stirred up the alreay large numbers of Leach'e Petrel along the east coast and produced a scatter of Sabine's Gull and Grey Phalarope but there were no major American rarieties associated with the storm
