I have just received a couple of histories of Black-tailed Godwits I have caught up with this year at Killingholme, North Lincs.
The first was ringed as an adult in 2009 in NE Iceland. It was seen at Pyewipe that autumn - only a couple of miles south of my survey site. This year it was seen at Caerlaverock in May, presumably en route to Iceland before being seen by me at North Killingholme in August. I have highlighted sightings on the map below (which doesnt want to centre in the right place...)

My other Blackwit is GO-OO, ringed as an adult female in 2003 in S Iceland, seen at this location the following month before moving to Cliffe Pools, Kent in September 2003. It seems to over winter in Kent as it was seen on the Swale Estuary in February 2004 & 2005. Post breeding it was seen on the Thames Estuary in August 2005. It was then seen next in July 2006 at Northward Hill, Kent, presumably as a failed breeder. That winter it stayed around the Thames estuary with sightings at Leigh, Essex and Cliffe, Kent before moving onto the Swale Estuary in March 2007.

GO-OO returned to the same site in Southern Iceland in June 2007 to breed before being seen around the Thames that autumn at Leigh & Cliffe. In early January it was seen on Canvey Island. The bird was not seen again for 2 years before subsequently being seen several times on the Medway in April, 2010. Finally for now it was seen by myself at North Killingholme in August 2010. As can be seen from the map below this bird spends most of its life on the outer Thames estuary. Killingholme is probably a major stopover point en route from Iceland. It is worth zooming in on the Thames area to show usage of the estuary.
