I have two other WTNT sightings to record:
1. Twelve birds swooping low over an open paddock at Kyeamba, NSW, about 70 km SE of Wagga Wagga on 2 February 2011.
2. 30+ birds circling low over canopy of Box-Gum Woodland on the edge of Woomargama National Park, c. 8 km SE of Woomargama, NSW on 15 February 2011.
In each case, the flocks were ahead of storm fronts.
