So it was actually a group of about 119 Pintail and, if you look closely, 1 Wigeon.

Can't believe my duck radar is that rusty! I've only been away from the UK since September. Still, Ang Trapeang Thmor is the place in Cambodia to see these species, with recent counts of 157 on 28th January 2009 and 150+ on 6th February 2010. Wigeon is much rarer, but recent records include 4 with other dabbling ducks on the former date, so were presumably with Pintail on that occasion as well. More recently five were seen at ATT on 12th February 2011.
