Thousands of birds have been found dead at one of Western Australia’s most important inland wetlands, but the cause behind the mass kill remains a mystery. Meanwhile, hundreds of thousands of fish have died in Australia’s Darling River conditions and bats are falling from the trees in biblical proportion around Adelaide as a result of the extreme weather. Researchers and at least a few other people like you and me are concerned about other animals in the country, as a new wave of very hot temperature will hit Australia this week and dry weather is predicted to continue. Weather war is raging out there!
25,000 bats – flying foxes – died over two days last November as Australia experienced record-breaking temperatures of more than 42 °C (107 °F).
One week ago, hundreds of thousands of different kinds of fish have died asphyxiated in Australia’s Darling River as a result of the extreme weather conditions. Nothing will stop this fish kill unless we get proper river flows and water levels in our dams back up to normal.
Now, it was found that several thousand birds had mysteriously died at Lake Gregory – a permanent freshwater lake located between the Great Sandy Desert and the Tanami Desert and was previously described as the most important inland wetland in Australia.
A department investigation excluded bird flu and Newcastle disease as a cause of death, but later identified the presence of blue-green algae close to the lake.
According to biologists: ” The water level at the lake is very low, coupled with recent very high temperatures in the area, which may have contributed to the deaths of the birds. Waterbirds are vulnerable to these natural ecosystem changes. Recent rain in the area appears to have alleviated the issue.”
Yes, because, in addition to the record-breaking temperatures, Australia suffered periods of intense drought, causing water levels to drop and heat up. This set the stage for major blooms of cyanobacteria, which may have helped to deplete the dissolved oxygen in the water.
Researchers and at least a few other people like you and me are concerned about other animals in the country, as a new wave of very hot temperature will hit Australia this week and dry weather is predicted to continue. Flying foxes are likely not the only species that are sensitive to the extreme heat, but because large numbers of the bats live in urban areas, their deaths are hard to miss. “It raises concerns as to the fate of other creatures who have more secretive, secluded lifestyles.”
Thousands of birds, millions of fish and tens of thousands of bats die due to the ongoing weather war… Stop playing with our weather! Stop trying to control it! The level of threat to those sites is high … wetlands, rivers and parks are highly productive environments, but are also easily disturbed.
