The Queenstown Sod Farm has hosted a whiteness of Tundra swans (around 100) 
for the past 3 days.

BTW:  an Internet search (Wikipedia) gave me these names for a bunch of 
swans ... gaggle, wedge (when flying), bank, bevy, whiteness, gargle and 
eyrar.  I picked whiteness, although eyrar sounded interesting.
How about a 'wisp' of snipe or a 'doading' of sheldrakes?
