Resumen de Primera observació d'un moretó de collar Aythya collaris per al conjunt de les illes Balears
On 7th December 2007 a first-year male ring-necked duck Aythya collaris was observed and photographed at s’Albufera de Mallorca. If accepted, this will be the first record for anywhere in the Balearic Islands, even though in recent times this American duck has occurred fairly regularly during the winter months at certain sites on the Iberian peninsula.
