With a bit of help from their friends, the Ringing Team quickly tracked down this individual's origin - it was ringed and tagged as a nestling on 18 July 2008 in Villeneuve, France, 817 kilometres south of Horsey.
This is only the third foreign-ringed Montagu's Harrier to be found in the UK. The first was way back in the 1920s; a chick ringed in the Netherlands in June 1928 was reported (in unknown circumstances) in Suffolk a year later. The second was an unfortunate individual found freshly dead on a road at Invershin in Highland, Scotland on 7 October 2002, just 60 days after it was ringed as a nestling in France.
The map below shows just how close the origin of this week's bird was to that of the Scottish recovery.
