After all, a duck pond without ducks is, erm, a pond.”
On the esate where I used to live (not as in inner city block of flats just as in a range of what once were council houses) there was an area about half way up the road which everyone (well everyone who had lived there a number of years) referred to as
"The Horses Field".
Whilst it once had indeed had horses there, even years after the horses had gone, the field had gone and houses had been built on the land when asked where I was going I could still say to my mum
"Just going up the horses field" and she would know where I meant. In fact I have no idea what the cul-de-sac that was placed there was actually named (although I'm pretty sure it wasn't "The Horses Field"

).
That was the point, every in Amy's village still referred to it as "the Duck Pond" even though their hadn't been ducks there for years. The memory of the ducks remained long after they had flown the coop.
