I'm very curious to know more about this water bird.
People seem to oooh and aaah about it - some photographers set up hides to shoot it and at least one coachload of Scaninavians came to the River Dodder about five miles from Dublin citycentre, to see it. Why? Is it rare? Wikipedia deesn't indicate that it is.
I'm told that it's not so much rare as it's elusive.
