Survey details

Bad weather has arrived in Maroochydore and we are greeted with heavy low cloud and very poor visibility, not ideal for our low-level surveys, so we are forced to wait it out. Luckily by mid-morning the cloud lifts a little and we’re able to get underway.
Today’s counting started with a series of dams in the hills west of Maroochydore before we fly over Lake Weyba, a shallow estuarine lake.

The dams have low numbers of birds, a few Pacific Black Ducks, cormorants, grebes, egrets and darters.

As usual Lake Weyba has very few waterbirds to count before we head along the Noosa Rriver estuary. Housing developments in this area have intensified over the last decade and the river is crowded with boats and people, so we are not surprised there are very few waterbirds.

We head north past the tall dunes of Cooloola and Great Sandy National Parks where the beach front is heavily utilised by campers and four wheel drive vehicles. Skirting around Rainbow beach we head across  Wide Bay harbour and up over the hills of K’gari (Fraser) island. Several of the freshwater lakes on the island are full – of these, lake Eliza is the most famous for its crystal clear waters.
From here we head across the channel, past Hervey Bay and Bundaberg to the estuaries of Littabella and Baffle creeks in Survey Band 8. There are low numbers of waterbirds, mainly cormorants, white ibis, pelicans and egrets. Baffle Creek has an aquaculture development which was mostly dry with few birds; baffle creek had low numbers of egrets, terns, pelicans and cormorants.

From Baffle Creek we continued north to Gladstone to refuel – passing close to the bauxite mining operations at the port

where there are a number of heavy industries including a coal loading facility.

Refuelling completed, we continued our northward odyssey flying along the Narrows, a channel of water between Curtis island and the mainland that has large areas of important waterbird habitats.

Mangroves and mudflats with intricate fractal drainage patterns that are amazing to see from the sky.

Continuing on we head towards the huge floodplains of Herbert Creek and the Styx River. These catchments are a complex maze of mudflats, mangrove and saltmarsh that meet freshwater inflows and shallow floodplain swamps. They can support large concentrations of waterbirds.

Today the conditions were surprisingly dry given heavy rainfall earlier in the year – however there were large numbers of waterbirds – thousands of Magpie Geese, Black Duck and Grey Teal and hundreds of egrets, Black Swans and Pelicans. Also in the mix were Masked Lapwings, Hardhead, herons, Green Pygmy Geese, Brolga and ibis. There was a small rookery of nesting Magpie Geese on the Waverly Plains.

Carrying on north again, we head for the wetlands south of Proserpine. Several dams have thousands of waterbirds – mainly Magpie Geese, Black Duck and Grey Teal with reasonable numbers of egrets, whistle ducks, herons cormorants, pygmy geese and lapwings.

The natural lagoons of the floodplain are surprisingly dry and support moderate numbers of Black Duck, Magpie Geese, egrets, herons and ibis.
