Heavy cloud and rain greeted us the next morning as we fired up the aircraft engine and headed back to Menindee Lakes and Talywalka Creek to complete our surveys.

ÌýThe NPWS quarters and shearing shed on Kinchega NP were ringed with water – a beautiful sight.Ìý

Temporary wetlands Emu Lake and Kangaroo Lake were full, but supported only low numbers of waterbirds.

As expected Lake Tandou was dry and devoid of birdlife - its water supply has been so modified it no longer receives water or functions as a wetland even in a flood year. The last wetland on our schedule, Nettlegoe Lake was dry and we departed Band 4 and set our sights on The Darling Anabranch lakes 75 km to the south.

The Anabranch Lakes system was near full with the intriguingly named Lakes Popiltah, Popio, and Mindona all filled with water though supporting relatively low numbers of waterbirds. Once these lakes were surveyed we continued south to Mildura before turning east along Survey Band 3.

After a quick refuel in Mildura, we headed off again to survey across sections of the Murray with enormous volumes of water flowing in the channel and parts of the floodplain.

The Lowbidgee wetlands looked stunning with water everywhere, healthy red gum forest and some large breeding colonies of straw necked ibis, spoonbills and pelicans.

The pelican colony on Kieta Lake, which is a part of the Gayini Wetlands, had around 3,000 nests with most of the birds sitting on eggs.

Another Gayini wetland, Eulimbah, had a spectacular breeding colony of between 10,000 & 15,000 straw necked ibis in full swing.Ìý

We finished up counting and headed to Griffith as the light began to fade, collecting another big day of counting in the bag.
