More generally though, I've been meaning to say for ages that I enjoy reading your blog - really honest, engaging and well written!
Hope to bump into you in the field at some point, if we've not already, and good birding for the rest of 2025 and beyond.

I'll join the club of people who saw 300+ in one year, had lots of fun... but am not likely to repeat the exercise. I remember endlessly dipping Wrynecks, well past the point of caring (even though they're amazing!) and wondering what the heck I was doing now and again. So I can definitely relate!

Congrats Phil - quality find, and just reward for much effort on the patch!

This is news to me. The regular Northumberland wintering Black Scoter spends the summer off Varanger, Norway.

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.

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

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!

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.

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.

Are any of your species counts 'X'? I've seen a workaround suggested to replace these with estimated numbers and then try to resubmit.

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.

Very cool find, Steve! Display has definitely been seen in the UK before - I remember a glorious evening in Cambs with this bird for instance: www.birdguides.com/gallery/bird...

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 for picking this up Alan. I know Jenna's been able to help other county data managers with the same request v recently.

Hope it helps John - feel free to drop me a line if you run into any problem or have questions.

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.

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!
