• Resumen

  • During a ringing campaign of Yellow Wagtails, 2438 individuals were handled at the Ebro Delta (NE Spain) in September 1992. On 27th September 1992 an adult Yellow Wagtail with interrupted moult was trapped. The bird had renewed all its plumage during the postnuptial moult, with the exception of the two innermost secondaries, two to six feathers in the median and lesser coverts of each wing and the smaller feather of the alula in the right wing. This is the first record of interrupted moult in the species.
