Project: Eastern Australian Waterbird Survey
Observer: Richard Kingsford
Today was our last day surveying the River Murray. The Lower Lakes, the Coorong and the Murray Mouth is a very special place. Once again it had surprises for us in terms of the waterbirds.

We only had to retrace our steps along the River Murray from about Berri to Wentworth today. It was bumpy because the wind had got up. But still pretty interesting.

The River Murray in this part of its course had flooded many of the billabongs and lakes along its way. There weren’t many waterbirds but the scenery was stunning and the water was certainly going to kick start the many different foodwebs that are important for the health of this river. This is the first time I have seen so much water in the river at this time of the year, ‘drowning out’ the locks.

We surveyed upstream, buffeted by a strong tail wind, finding the billabongs near the river. Some of the lakes had more than fifty waterbirds but this was rare.

We landed at Mildura to refuel and then headed back to Sydney, passing over the intricate patterns made by the flood on the Lowbidgee floodplain of the Murrumbidgee River.

Next week – we survey the Lachlan which has had a huge flood. It will be great to get out there and see the extent of flooding, with one of the biggest breeding events of straw-necked ibis recorded underway.
