flying towards the silt trap near Isabella Drive, they did not stop. We checked the silt trap when we got there and there was no sign of them around or further down.
@AaronClausen @michaelb When I did a search for Australian Shelduck it only came back as Tadorna (Casarca) tadornoides where there are no sightings listed. To get to all the sightings had to use the Latin name Tadorna tadornoides, this may need to be updated so the search links to where all the sightings are. Thanks.
