In the latest batch of recoveries (more of which another day...) Kev received details of the Dunnock we controlled at Holme Pierrepont this year and it turns out it was ringed as a 3 at Rutland Water in September 2007 and therefore had moved 45km!
Although Dunnocks further east on the continent are known to be fairly long distance migrants, in this country the average recovery distance is less than 1km and less than 5% of recoveries are over 1km. Therefore this bird is something of a Ranulph Fiennes of the Dunnock world.
P.S. We've just discovered it was ringed by our friend Candice Barker!
