First GPS tracking evidence of Icelandic Whooper Swans wintering in the Netherlands 🇳🇱! Whilst we know that small numbers of Icelandic birds winter in the 🇳🇱, this is the first we've tracked. Great insight into their journey to 🇳🇱 via 🇬🇧 & how long they stay there 👌🏻 @stephen8vickers.bsky.social

Back from a great @waterbirdcm.bsky.social trip up to the Solway Firth. As part of our work assessing the mixing of naturalised Barnacle Geese with the migratory populations, it's important for us to search for our colour-marked birds in wintering migratory flocks 🧐 #monitoring

The latest movement maps of our @waterbirdcm.bsky.social naturalised Barnacle Goose ringing programme. Here's the annual movements from the 14 UK breeding colonies we've marked birds at. Thanks to everyone who contributes sightings! Map thanks to @stephen8vickers.bsky.social #Monitoring
