Greenish Warbler at Norwick
A sound recording of it calling here.
Yellow-browed Warbler bearing a Norwegian ring
From the back of the camera I could read NOR. Glen Tyler very kindly messaged me to say he'd recently caught a Goldcrest with a Stavanger, Norway ring. That enabled me to also read VANG.
The BTO website suggests only seven foreign ringed Yellow-browed Warblers have been subsequently recorded in the UK, four of them from Norway.
