It was a week of changeable weather, with dull, grey and chilly days intermixed with periods of bright blue skies and blazing sunshine. Birders in both coastal and inland areas were treated to good showings of both Garganey and Wood Sandpiper, alongside a decent arrival of Temminck's Stints. This last species was recorded at 16 sites, primarily in eastern areas of England and Scotland, including threes at Minsmere RSPB, Suffolk, and Gibraltar Point, Lincolnshire. Three at Ripley Farm Reservoir, meanwhile, is the largest group reported in Hampshire since the BirdGuides sightings service began in 2000.

We cast our eyes to the Isle of Wight for this week's headline bird, with an adult Yellow-billed Kite at Lynn Tip from 10th. This, the Afrotropic counterpart to Black Kite, at first glance seems a highly improbable vagrant to British shores. However, a curious pattern of records has begun to emerge across Europe in recent years. One in The Netherlands, Germany and Denmark in April 2021 was followed by birds in both Estonia and Serbia in April 2022. Photos also emerged this week of one at Springfield Farm Quarry, Buckinghamshire, on 29 April 2019. Where are they coming from?

Although the species is largely resident in its native Africa, it is prone to long-distance vagrancy on occasion – amazingly, one reached Cayenne, French Guiana, on 3 May, becoming the first for the Americas. That said, you would have to presume that one reaching Britain would be the longest of all long shots, and the prevalence of the species in captivity – both in Britain and elsewhere in Europe – is always going to cast a huge shadow on doubt of an out-of-range bird. Perhaps not one to ink into the notebook just yet!

A Song Sparrow on Bardsey Island, Gwynedd, on 9th had twitchers springing into action. A brilliant co-ordinated effort from observatory staff and local boatmen allowed approximately 30 birders to reach the island that afternoon, where the bird remained – albeit mobile – into the evening. Impressively for a species with just 10 (or 11) previous British records – and five of those from Fair Isle – this is Bardsey's second. The first – Britain's third at the time – resided on the island from 5-8 May 1970. Unfortunately, this latest individual bucked the trend of extended stays and proved a one-day bird, having performed an overnight disappearing act.

The very same morning, a Dark-eyed Junco was discovered at Rattray Head, Aberdeenshire. Remaining reliable on its adopted seed pile until 11th, Scotland's last widely twitchable individual came as long ago as the turn of the century, making this one very popular indeed. It represents the first for the Aberdeenshire mainland, with previous records concerning birds on the Maersk Curlew offshore oil platform in May 2000 and May 2005. Both of these species are prone to crossing the Atlantic by ship – a trait emphasised by a record of singles of each onboard Federal Severn between Canada and Norway off Orkney at the end of April. News later emerged of another junco at High Kelling, Norfolk, on 6th.

Just down the road, one of the week's stranger finds concerned a drake Baikal Teal cavorting with Mallards on a disused coastal lido at Macduff, Aberdeenshire, for a short period on 10th. Unringed and fully winged, its somewhat strange location and chosen carrier species might yet prove a barrier when it comes to acceptance. If it does meet the bar, it would become just a second for Scotland after one on Fair Isle in autumn 2021.

Subalpine warblers are a spring highlight for many, although recent splitting has added an added layer of complexity to these tricky Currucas. Remarkably, this week saw each of the three species represented in Britain, with a male Moltoni's Warbler trapped and ringed at Portland, Dorset, on 12th the most notable in terms of number of records. The other two were in Mainland Shetland – an Eastern Subalpine at Clickimin Loch and a Western Subalpine at Quendale. A male at Sandhaven, Aberdeenshire could not be identified conclusively from the images taken, while a probable Eastern proved very elusive at Prawle, Devon.

An arrival of Great Reed Warblers in East Anglia saw no fewer than four found, with males belting out their croaky tones at Boyton Marshes RSPB, Suffolk, and Titchwell RSPB, Cantley Marshes RSPB and Pensthorpe Waterfowl Park (all Norfolk). A fifth remained in Somerset, while the first Blyth's Reed Warbler of 2023 was on Westray, Orkney, on 13th. Gloucestershire's first Iberian Chiffchaff was an excellent find at Staple-edge Wood, Gloucestershire, on 14th, with another hanging on in East Sussex.

Four Red-backed Shrikes were on the English east coast, with further birds in Cornwall and Shetland (two). Elsewhere, Golden Orioles were in five counties, Hoopoes visited 18 sites and a young male Common Rosefinch sang near Hornsea, East Yorkshire. Four Wrynecks were logged – birds in Scilly, Cheshire, East Yorkshire and Lothian – although all proved brief. European Bee-eaters overflew Spurn, East Yorkshire, Bull Point, Devon, and Southwold, Suffolk.

On 14th, the White-spotted Bluethroat at Slimbridge WWT, Gloucestershire, for its third year. Female Bluethroats were on the Isle of May, Fife, and Out Skerries, Shetland. Shetland enjoyed a good spread of Grey-headed Wagtails, with one more at Boldon Flats, Durham. A female Citrine Wagtail was still on Fair Isle and a Greater Short-toed Lark was on St Mary's, Scilly, with a late Shore Lark on Isle of Noss, Shetland.

It was another excellent week for Pallid Harriers, with birds in five counties. Two ringtail Montagu's Harriers kept close company near Breydon Water, Norfolk, with others still in Cornwall and Co Antrim. A female Pallid or Montagu's Harrier south at Spurn, East Yorkshire, added to the totals. Other notable news concerned a Gyr Falcon at Cove, Highland, on 11th and a probable Short-toed Snake Eagle west over Walkford, Dorset, on 14th. Eight sites enjoyed European Honey Buzzards and Red-footed Falcons were at Stodmarsh NNR, Kent, and Ludham Bridge, Norfolk.

Five days since departing the Northumberland coast, the Grey-headed Lapwing resurfaced at Lossiemouth, Moray, on 13th, to the glee of Scottish birders – but had moved on again by the following morning. It was a decent week for Pectoral Sandpipers, with birds at five sites, including two at Cliffe Pools RSPB, Kent, on 11th. An American Golden Plover graced Cemlyn Bay, Anglesey, from 9-12th and Long-billed Dowitchers lingered in Norfolk and Hampshire. Trips of Eurasian Dotterel were in Norfolk, Lancashire, Ceredigion, Shetland and the Outer Hebrides, and a Eurasian Stone-curlew was still on Fair Isle. A new Black-winged Stilt was at Cahore Marsh, Co Wexford.

A Squacco Heron was at Combe Valley CP, East Sussex, on 14th, where a continuing Black-crowned Night Heron played second fiddle. Although the influx has slowed somewhat, 14 Black-crowned Night Herons were at 11 locations, with 11 of those consisting of new arrivals. The latest species to arrive en masse is Glossy Ibis, with some bumper flocks recorded including 17 over Skomer, Pembrokeshire, 16 over Cotswold Water Park, Wiltshire, 13 at Hayling Island, Hampshire, and 12 over Appleford GPs, Oxfordshire. Purple Herons were at 11 sites, with new birds in Cornwall, Dorset, West Sussex, Suffolk and Norfolk. Wandering White Storks were noted as far north as Ruswarp, North Yorkshire.

Spring skua passage is always a highlight in the Outer Hebrides. Although yet to kick off in earnest, 13 Long-tailed Skuas flew past Aird an Runair, North Uist, on 14th, accompanied by 11 Pomarine Skuas. In Shetland, a lone adult Long-tailed was on Fair Isle on 11th and, surprisingly, an adult Sabine's Gull off Norwick, Unst, on 14th is the island's first-ever record.

The adult summer Laughing Gull afforded some excellent views in the Lesser Black-backed Gull colony on Gugh, Scilly. Elsewhere, an adult Ring-billed Gull continued its residency at Loch Turret Reservoir, Perth and Kinross, and the second-calendar-year Bonaparte's Gull was still at Hayle Estuary, Cornwall.

Finnish birders enjoyed an excellent week: the nation's third Baikal Teal at Ähtäri was complemented by a Caspian Stonechat at Pasalankylä and a Sociable Lapwing at Rannankylä. A young male Lesser Kestrel flew over Bulbjerg, Denmark, on 10th. A White-tailed Lapwing made it to Varberg, Sweden, before moving to Slevdalsvannet, Norway – where it became just the second national record. Two more were at Karcag, Hungary.
The influx of Mediterranean visitors continued to reach Iceland, with a Gull-billed Tern at Eyrarbakki and a Black-winged Stilt at Álfsnes – just a couple of weeks after the nation's second. An adult drake White-winged Scoter continued at Reykjavík, with another White-winged at Svenska Högarna, Sweden.
A Greater Sand Plover – Poland's eighth – was at Hel and a first-summer Slender-billed Gull lingered in Germany at Gremsdorf. A Pacific Golden Plover and Maghreb Little Owl were on Sicily, Italy.
