two Swamp Harriers did a lap around Kelly's Swamp and all the ducks and other small birds flew off, all that stayed was a Royal Spoonbill and white Ibis. 10 minutes later the Swamp Harriers were back and did the same thing again, they went up the end of Kelly's Swamp then past the hides including Snipe Hide and then looped back again and then up in the air for a short time then were gone. They were so fast. The first photo is a lucky shot of one that flew right past us in front of the hide window.
