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!

British vice-counties | Biological Records Centre

The main new feature is the option to assign records to Watsonian vice-counties, as typically used in biological recording. Region boundaries are used from here: www.brc.ac.uk/article/brit..., and seem to be working well based on tests with data from East Anglia. Interested to hear feedback on this

eBird County Data Cleaner

Calling all #ukbirding County Recorders interested in cleaning and extracting data from eBird. I have updated the app I developed with @ollie333.bsky.social, and moved it over to a new hosting platform. You can now find it here: dbradnum-ebirdcountyrecordcleaner.share.connect.posit.cloud

Amazing! Have a fantastic trip, and please keep posting the updates and photos when you're able. I remain very envious...

Hi! It's built with Skyfeed. Once you have that installed and set up, you can navigate to an existing feed, clone and then edit to suit your needs. I'm away this weekend, but happy to pick up over DM after if you need a hand. Pretty sure I found some tutorials online too.

Just reiterating what Dawn said - these are certainly Turnstones (Ruddy Turnstones, rather than Black Turnstones, for the avoidance of doubt). Green Sand would be on fresh water not salt, and unlikely in tight roosting flocks like this.

There's room for 1 or 2 cars only here, just N of bridge - maps.app.goo.gl/uaRs7codj37j... - then small path leads out E for c200m to view flood and Marshes to N. Pig farm also to N, which I assume is where the Hoodie is hanging out.

Excellent birding at Abberton in long-awaited sunshine today: Black-throated Diver, drake Lesser and 4 Greater Scaup, drake and redhead Smew, 4 Bewicks Swan, 9 Med Gull, 10 Black necked and single Slav Grebe, and a somewhat Lesser Scaupy female Aythya hybrid! #essexBirding
