• Results of the 1998 winter census of wildfowl and shorebirds from 47 localaties of the Balearic Islands are summarized. Over 17.921 individuals belonging to 58 species were recorded. The most abundant species was Mallard Anas platyrhynchos, followed by coot Fulica atra. The great increase of Purple Gallinule Porphyrio porphyrio, species introduced into the Albufera of Mallorca in 1991, which consisted of 28 individuals and currently has an estimated population of 150 is remarkable. There was a count of three Marbled teal Marmaronetta angustirostris, species who also bred in 1997 in the Albufera of Mallorca.
