NEARLY 30,000 birds are wintering in the Balearic wetlands.

Some 73 separate species are staying in 35 different wetlands around the islands, according to green group GOB.

Mallard ducks are the most common visitor, with egrets and the peewit also regularly seen.

Over 100 volunteers counted the different birds as part of the 52nd census coordinated by Wetlands International – held in 143 countries around the world.
