After 30 years(!) have retired my old Dialyts. They'll be able to sit in a rocking chair on the porch and tell the new binoculars how there used to be more birds in the old days.

Five subalpine warblers trapped on Lundy this spring + done genetically came out as 1 Western (iberiae/inornata), 1 nominate Eastern (cantillans) (S Italy) and 3 albistriata Eastern (Balkans/Greece/Turkey)!

Not that anyone cares what I think, but I still believe the May '98 Druridge curlew was a Slender-billed, AND that the hard documentary evidence proves it. Figures from
@britishbirds
DNA on Black-crowned Night Heron, Dingle Gardens, Shrewsbury, (eventually taken into care where in good health & eating all the fish) confirms it's an American one N. n. hoactli. ID'd w feathers that fell out in fight with mallard after it tried to eat her kids.
Cornwall Rufous-tailed Scrub Robin DNA is 2% different cf. previous bushchat DNAs (= a lot!) (= 'unknown specimen'). But others are from Israel/further S/E. Suggests Cornwall bird is from unsampled nominate African/Iberian population & poss future split. Pic Dougy Wright
Top take-home points from 'CSI: Birding' talk
@NTBirdClub
last night:
1) If it looks like an Elegant Tern, it is one - tick it;
2) Genetics has RUINED Isabelline Shrikes;
3) Do NOT send us anything from a Crossbill or Redpoll;
4) Dead birds don't sing properly.
5) Weird shit.
We didn't consult parliament but DNA from moulted feather supplied by Graham Jepson has confirmed Staines Horned Lark is definitely of Nearctic origin, possibly one of the western populations.

Hope someone is follwing the Cape/Kelp Gull round with the pooper scooper. The only bird we ever sequenced (from The Gambia) was actually genetically identical to South American birds, not South African ones.
This Hen Harrier was so bothered by its satellite tag it shot itself and died of sadness. On a grouse moor. You do wonder about the motivation of organisations that see this and attack the tagging programmes.
Super news - new, unnamed, genetic subspecies of Common Chiffchaff that colleagues had breeding on Mount Hermon in 2012/13 now also found singing in S Turkey

In a dramatic twist, the 'Eastern' Yellow Wag from Rattray Head, which didn't look or sound much like one, & that I didn't go to see, has come back as genetic Eastern YW, of 'northern tschutschensis' group. Thanks to
@andyhidef
for poop and also some of the bird's.
@BirdGuides
Here in 'Britain's Top Vicarious Birding Lab™' we never give up on a good bird. Soooo... 3 years after it turned up and 2 years after it made the British List, we have got DNA out of poop of Tiree Yellow-bellied Flycatcher supplied by Chris McGuigan &
@bubobilly
and all is well.
Argh ffs! Hanging out the washing and a Greenish Warbler starts calling in the back garden.... got my bins just in time to see it flying out over the house. Hanging around to see if it comes back.
Everyone cheering Lorraine Kelly today remember that she is only acting the role of Lorraine Kelly for tv and if she was actually *being* Lorraine Kelly on telly she'd had to pay her million quid tax bill and there might be some more nurses.

For those who like this sort of thing, DNA results on the American Herring Gull from Newlyn earlier this year... show that it is definitely not European HG, and is definitely from the Nearctic/Arctic/Pacific clade. Work by

Few things in birding life more tedious than people who can't/won't twitch a rarity moaning that it would be easier/cheaper/purer to go and see 100s of them in the States/China.
That faint gel band I posted a couple of days ago has turned into a confirmed ID of Ireland's first Alder Flycatcher. Dirty work done by Steve Millar hiking poos from under favourite perch once it left.
@bunkernut333
Pallas got so many good things names after him... best Phyllosc Warbler, best Gropper, best sandgrouse, best gull, even best moggy, but then he also got that reed bunting which kinda evens things out.
There were never any targets for removing birds from the British List.
Well there were targets but I wasn't told.
OK I was told but I didn't read the memo.
OK I read the memo and increased the targets but they were only ambitions not targets.
And that's how I left BOURC.
It took a while, but DNA from fecal sample confirms this accepted Eastern Black Red, (Easington 25/10/16) as 'Eastern', probably phoenicuroides. Hard work done by

Still working on genetic ID of 'red-tailed' shrikes: Red-backed & Turkestan share DNA; lack of comparative sequence. But 2022 Bempton Shrike DNA falls within phoenicuroides/collurio clade consistent with ID as Turkestan. Tree based on Genbank data.

So... a birdstrike, hit plane in April somewhere between Oslo and London, came back as Tawny Pipit on DNA. Presumably a good record for Oslo, London or the North Sea recording areas! :-D

It is a truth universally acknowledged that you never see a Long-tailed Tit on its own. If you *do* see a Long-tailed Tit on its own, it's up to no good. Keep your eye on it.
More DNA news. Not that this needed DNA, but poop sample from the Spurn Two-barred Warbler has confirmed it was genetic plumbeitarsus.

Rarity assessment over time. Specimens to sight records, to photos and DNA. What will future generations make of records in the Badlands period supported only by descriptions? Will DNA take the fun out of birding? Drew this for the Bernard Tucker Memorial Lecture

...AND THEN BOU REVIEWED AND REJECTED IT EVEN THOUGH IT SHOWED FEATURES THAT WERE 100% DIAGNOSTIC OF SBC IT WAS CRAZY LIKE GROWN MEN THROWING A WOBBLY COS SOME OF THE PHOTOS WERE BLURRY I MEAN COME ON IF IT HAD TURNED UP IN WHEN DIGITAL TOGGING WAS A THING THEY'D HAVE NAILED IT!!
Long gestation, but this paper in latest BB led by
@YosefKiat
describes grey-rumped Little Terns from Eastern Med and Red Sea as distinct from nominate European birds. So much so that all records of Saunders's Tern from Israel now rejected 😭

Sadly(?!) the Arctic Warbler from Hartlepool Headland in October came out genetically as bog standard Arctic and nothing more Kamchatka-esque.
Analysis by

I hear a displaced feather from the Hartlepool Arctic Warbler is being supplied to
@docmartin2mc
(hopefully to be repeated with every future handled Arctic Warbler that drops a feather). We will see or not!
Finally, decent views of the long-staying Eastern Stonechat at Quendale this morning. Its colours depend significantly on the light. Sibe rather than Stejneger's I think? Hopefully

will deliver a definitive answer idc.

Massive THANK YOU to everyone who donated in 2023. donations have paid for ID (or confirmation) of:
Western Olivaceous Warbler (Whalsay)
Alder Flycatcher (Skokholm)
Yellow-bellied Flycatcher (Tiree 2020)
Great-tailed Grackle (Nolton Haven)...
Just heard back from
@docmartin2mc
that our Iberian Chiffchaff on 25th April has been confirmed through feather samples obtained when it was ringed. Great work all by all concerned! First for the island!
Autumn in our lab: we wait eagerly for the easterlies that blow the postie to our door with offerings of Siberian DNA goodies... Whether the posties are drift migrants, reverse migrants or pioneering outliers on the migrant postie vector map remains an open question.
Pied , Cyprus and Eastern Black-eared Wheatears show no consistent genetic differences. Western Black-eared is genetically divergent and prob different species from Eastern.

With the help of the guys at Aberdeen University I've managed to track the Lesser Whitethroat species which was in my garden last week to a Bird rung at Bempton cliffs this autumn. Its a Blythi. An armchair tick in more than one sense.
Some positive news from
@docmartin2mc
and his team at Aberdeen Uni last night. The DNA results on the Green Warbler came through and we’re happy to say they’ve confimed what we thought, it’s a Green Warbler! Big thank you to Martin and his team :)
The autumn has started in Britain's self-styled 'Top Vicarious Birding Lab', with DNA extraction from Skokholm likely-Alder Fly, a Bonelli's warbler, some unstreaked Acros and a few other odds n sods.

@PortlandBirdObs
Come up to the lab and see what's on the slab. Currently, we are validating genetic identification of Daurian and Turkestan Shrikes, hopefully to facilitate field ID of first winters and ticks for all.
Work made possible by your donations thanks!

Poop samples... 1) the Bempton Turkestan Shrike, probably a lot of beetle juice and 2) East Halton Pits weirdo gull, probably a lot of unspeakable slime.
Four more Daurian Shrikes from the
