Ringed adult graellsii, ringed in the U.K. on 13 March 2004 at Stoke Orchard landfill site, near Wingmoor Farm, Gloucestershire (51.56N 02.06W).

New mc and inner gc indicate active complete moult (although no obvious moult gaps in wing-coverts). Outer visible primaries still old, which is late for this taxon.
