Occurrence date	2023-03-24 Supplied date "2023-03-23T13:30:00Z"
End day of year	82
Event remarks	Water levels very low at the start of Whicker Road with a lot of exposed mud which was being investigated by a large number of species including some not often seen. For example Australian Spotted Crake and Wood Sandpiper. The number of species of ducks present has also increased from previous visits, Pink-eared ducks, Blue-winged Shoveler and Hardhead were present in double figures for the first time for a while and quite large numbers of both species of grebes and dotterels were present in much greater numbers than previous visits. Large numbers of Little Black Cormorants (one flock of 29 and another of 20 were present although one a single Little Pied Cormorant), and a very large flock of Little Corellas (in excess of 200) flew over from the grain silos. Surprisngly not a single species of raptor was observed. 46 species were observed in total the second highest total recorded in 40 surveys.
