• Resumen

  • The remex moult of 28 adult and 2 1 first winter Little Stints was checked in Majorca (Balearic Islands) during November and December 1991. The intensity of postnuptial moult was very low: only 6 (30%) out of 20 birds with unfinished moult were in active moult, with ari average of one feather growing per wing. Fourteen birds had suspended their moult. First winter birds moulted no primaries or secondaries in the postjuvenile moult, but they moulted the tertials to varying extents. These stages of moult can be explained by the ecology of the area, which is one of the most northerly wintering grounds for Little Stints.
