Hello Mike,

Some years ago I was dozing (fishing) from a small dinghy in the middle of 
Narrabeen Lakes (abt 25kms N. of Sydney CBD) on a still, sunny day in December 
, when I found that I was suddenly surrounded by Swifts. They were swooping 
down in  great arcs and skimming across the placid surface of the lake. The 
birds were all about me, some, only a couple of metres away. They were no 
longer mere dots in the sky but large birds with wingspans of about 15 or 20 
inches. As they travelled over the water the beaks were opened and they 
appeared to be scooping up the water, then zooming almost vertically, leaving 
neat "vee's" over the mirrow surface.Apart from the close approach, I was 
impressed by the fact that it was salt water. There were fifty or sixty birds 
in the flock and I am curious to know whether drinking saltwater is a normal 
action of WTNS.
