Hi Jared, Mark - here's a link to the app: dbradnum-ebirdcountyrecordcleaner.share.connect.posit.cloud
It's also built in R, a Shiny app, and can share a link to the underlying code if helpful. See the instructions tab for details, and feel free to drop me a DM if any questions or issues.

Always one step ahead of me 😉

I'm not aware of one, Jake (bit far south for me!) - but @darylrhymes.bsky.social is there fairly often and might know?

A superb bird and a brilliant way to end the week. Echo the congrats to Chris and Sean, excellent find.

A fantastic mad rush to locally twitch the Arctic Warbler in Essex at Great Wigborough church this evening. Initially a no show, i felt a dip coming on and then refound by Stuart. Well done on the finders @snixon66.bsky.social and @chrispoole050.bsky.social. 👍 My 2nd for Essex #essexBirding

Nice photos! I think you've got a Little Stint rather than a Sanderling in the first couple of photos here.

Yes, I'd noticed this too - the bears were definitely a surprise!
Interested in views or opinions about whether I should amend the feed to remove location names, so it only picks up the hashtags? Or perhaps just remove those larger town names, and keep less ambiguous sites like Abberton?

Just to add to this, after doing a little bit of testing - everything appears to be working as expected with 2024 eBird data from Bristol, Somerset and Gloucs, using the observer list from eBird Central in March 2025. Happy to chat via DM or email if you're still running into a problem though.

Hi Rob - thanks for reaching out. I've not done any testing with the app for a little while, so maybe something has changed slightly in ebird data extract format that's led to a bug with eBird users. Suggest we connect over email so I can understand the issue better and test it; will DM!
dbradnum.bsky.social
That's not really how Bluesky works though? The point of the feed is to only pick up posts about that theme - and then if folk want to read everything you post on all themes, they follow you. That's the best of both worlds! People that keep posting off-topic stuff to a feed end up blocked from it.

Apparently version 3.3.1 of the app (just released) should fix this problem.
dbradnum.bsky.social
Glad it worked. And hopefully the need for the workaround will only be brief - I guess there is a bug here somewhere and, fingers crossed, it will be fixed fairly quickly.
dbradnum.bsky.social
Are any of your species counts 'X'? I've seen a workaround suggested to replace these with estimated numbers and then try to resubmit.
dbradnum.bsky.social
Ah, that's good to hear (in both senses of the word) - they seem to have been a little more difficult to find there this year, for some reason. Hopefully all of these will be paired up.

Another birding paper! 🐦 Where do the Nearctic landbirds that show up in Europe each autumn come from? We usually assume they come from NE populations, pushed off course by bad weather - but is that the whole story? #ornithology 1/3

Based on plumage variation, we are confident there were 9+ red-footed falcons at Carlton Marshes over the last three days. 2 adult male 3 females seen hunting dragons together, with at least 4 sub-adult males.

Interesting to see the origin of this bird - a little disappointing but unsurprising that it's of captive origin... #suffolkbirding

Thanks to Chris Batty for pointing out that the mobile Dalton-in-Furness White Stork appears to be up to its old tricks at this time of year. Interestingly it appears to have gone over Scarborough on more or less the same date two years running. Things may get simpler if it's ever caught!

Congratulations! Fantastic place, and fantastic news.
dbradnum.bsky.social
Excellent! Glad it worked well, and thanks for letting me know.

Thanks for picking this up Alan. I know Jenna's been able to help other county data managers with the same request v recently.
dbradnum.bsky.social
Hope it helps John - feel free to drop me a line if you run into any problem or have questions.
dbradnum.bsky.social
No problem, hope it helps! I reckon the app should be able to process a year's records for all of Wales in one go, without any need to do individual counties one at a time. Let me know how you get on.
dbradnum.bsky.social
The app includes a tab giving instructions for use, with a couple of short demo videos. Feel free to drop me a DM with any questions!
