The only project in Sweden currently utilising this method for Jacks is here at Ottenby Bird Observatory, with super interesting and rewarding data just in the last two Autumns with 40 tagged this year. Still much to learn about this species!

A bit stunned when this Bridled Tern appear in my ‘scope 150m infront of the hide at Fife Ness. It then hung around for 3 hours roosting on a buoy and feeding inshore (when pic taken) before heading off NE. A first for Fife. Glad we chose today for the all day seawatch! #birdingFife #rarebirdsUK

Great morn, looking/surveying a local spot for Jacksnipe..finding 7 via Thermal Imaging. Super/mysterious Birds that have the ability to avoid the general Birding radar most of the time. Photo recorded at a respectful distance with a 1260mm lens & cropped. Also 23 Common Snipe.👌🏻 #birds #ukbirding 🪶

For my first post here, I’m happy to share our new paper just published in @ibisjournal.bsky.social Thanks to a great team effort, we made a small step forward in the study of Siberian vagrants in Europe and clarified the status of two (pseudo) vagrants: the YBW & the Sib Chiffchaff. Some results 🧵

With passage seemingly over here @Ottenby, 55 Jacks ringed (25 MOTUS) has been the best Autumn on record. Undoubtedly boosted by thermal tech, catching these gems during the day will never get old.
