You can now find links and introductions to all of my #RShiny apps here: shvickers94.github.io/BTO_Ringing_Ap… Recommendations for improvements or entirely new apps are welcomed.

The Whoopers are starting to move and will soon be back on their Icelandic breeding grounds! Since @WaterbirdCM started ringing Whoopers in 2023, we've tagged >600 inds. and gathered >750 sightings. Please keep an eye out and continue to report any sightings to us as they leave!

In Feb 23 we undertook a census of the UK naturalised Barnacle Goose population. The aim to produce an updated population estimate & report on winter distribution. Results have now been published in @BritishBirds, with our thinking on future monitoring needs #Ornithology 1/7 ⬇️

@whitfieldbenson @CVLbirding Ringing recovery covers all subsequent encounters dead or alive from anyone that isn’t the original ringer

@CVLbirding Ringing recovery means it is dead ?

A ringing recovery wasn't something I was expecting from a cruise along the South Shetlands but here we are. Anyone know who in the world has been ringing South Polar Skuas?

A special thanks to my co-authors and funders. This work was completed as part of my PhD thesis at @biouea/@ueaenv/@uniofeastanglia partnered with @audubonsociety 10/10

We think this is because dispersal into new breeding areas is always passed to the next generation when born there – you only need to return to a known location. Conversely, a new non-breeding site isn’t automatically passed to the next generation. 9/10

New paper published today in Movement Ecology! We show N. American birds that migrate in flocks have greater long-term non-breeding range shifts, particularly if flocks are mixed-age. We link this to social learning in novel mig. route development. rdcu.be/d57Mw 1/10

New paper! If you use time-lapse cameras, this one's for you! Proud of this collaboration with @UEA_CMP's Marcus Jenkins & Michal Mackiewicz to improve object detection for time-lapse imagery using temporal features. 📷🖥️⏲️ Open Access @Sensors_MDPI: mdpi.com/3088004

* picture is from original ringing in 2020, I haven’t recaught it!

1450 days and 4 return migrations later and back just 7km from where I originally caught and ringed it!

Ok! Come on let's follow this lot to where they're sleeping tonight... A thread🧵 #Ornithology 1/7

Since 2023 we've caught & colour-marked nearly 600 Whooper Swans & we need your help to find them! 🧐 Please check any flocks you may see & let us know what you find...
