I too have frequently heard of ducks (mostly pacific Black Ducks) landing at 
night on corrugated iron roofs of outback sheds, but have not seen it 
personally. 
On Christmas Island the 3 species of frigatebirds are in the habitat of 
drinking from freshwater pools in mine clearings.I sometimes saw them trying to 
drink the air just above hot dusty road surface. I assumed that their vision 
(which is adapted to seeing fish below the surface, flying at night, and 
probably many other things) must have mistaken heat haze off the road for pools 
of water.

Subject: Grebes mistake car park for lake
 
I once heard a rumour that grebes often land on the runways at Perth airport 
and every morning a truck goes out with people to gather them up and return 
them to a nearby wetland - but I have never seen/heard proof of it.  Now I'm 
tempted to see if I can find out more.
