Our wandering Barnacle Geese (originally ringed in North Yorkshire) are touring Germany! First seen close to the Austrian border in January, they are now in Lower Saxony. Heading home? 🤗

They are heading home!

Our colour-marked Whooper Swans are migrating back to Iceland, please keep an eye out for our colour-marked birds. White leg rings can be reported to waterbirdcolourmarking.org/report-a-bird-…

Having a snooze after crossing The English Channel? Here is 236N in The Netherlands 🇳🇱, one of 3 of our birds reported from Groninggen in the last couple of days

Vanmiddag in het Noorderplantsoen in Groningen opeens 2 in Engeland gekleurringde Kokmeeuwen. Dit is een teken dat de voorjaarstrek flink op gang komt. Beide vogels waren erg mak. Beide waren in een park geringd. Sovon Vogelonderzoek Nederland, Vogelbescherming NL. x.com/waterbirdcm/st…

Here is 221N, our first overseas sighting for 2024. The bird is in The Netherlands 🇳🇱 having spent the winter in Norwich, UK 🇬🇧. In previous years the bird has been seen at a breeding site in Finland 🇫🇮 so presumably its on its way there! Best of luck with your journey 💙

The team are staying WWT Welney this weekend, touring the Nene & Ouse Washes, looking for some of the 500 colour-marked Whoopers we ringed in Iceland last year 😊

2023 is ending and we just want to say a big thank you to everyone who has reported sightings this year. We've tagged another 34 swans (now 242 since we started in 06/23), gathered 674 sightings (taking us past 3k), and joined collaborative research efforts with Lincoln Swans!

2023 has been another busy year for us! With 1,216 waterbirds colour-marked of 11 species. Three new species have joined our studies & our online app has processed 12,500 sightings. Overall our datasets contain 63,400 sightings. Stay tuned for species updates!

Publication day! See the below thread on our latest paper looking at moult migration, site fidelity & survival of Canada Geese ⬇️

This week, we've managed to catch 142 Black-headed Gulls for ringing, with 11 of these having GPS tags fitted. We also managed to read the rings of 164 previously ringed birds, topping up our newly ringed & resightings datasets nicely! #NWBHGs
