Common moorhen (Gallinula chloropus)

Took a walk at a nearby river side. And spotted this one. Never seen those birds before. Was quite bit surprised. Its like a hen that swims. It walks like a hen, talks like a hen, and then goes into water and swims like a duck. :)

And the two flickr versions of it walking and swimming:
