Australian Bird Names is aimed at anyone with an interest in birds, words, or the history of Australian biology and bird-watching. It discusses common and scientific names of every Australian bird, to tease out the meanings, which may be useful, useless or downright misleading!

The authors examine every species: its often many-and-varied common names, its full scientific name, with derivation, translation and a guide to pronunciation. Stories behind the name are included, as well as relevant aspects of biology, conservation and history. Original descriptions, translated by the authors, have been sourced for many species.

As well as being a book about names this is a book about the history of ever-developing understandings of birds, about the people who contributed and, most of all, about the birds themselves.

Australian solar eclipse, Friday 10 May

Aussies can catch a glimpse of a so-called annular solar eclipse this week, the only one until 2035.

ON FRIDAY MORNING, an annular solar eclipse will be visible from parts of Australia, for the last time until 2035.

An annular eclipse occurs when the Moon, in a distant part of its orbit around our planet, covers a large portion of the Sun’s area as seen from the Earth, hence a ring or ‘annulus’ is left around its edge. This is not to be confused with a total eclipse, the last of which was visible from Australia in November 2012. This annular eclipse is the first to be visible from Australia or New Zealand since 1999.

The only sizable town that lies on the path of annularity – where a complete viewing of the eclipse is possible – is Tennant Creek in the Northern Territory. The Musgrave Roadhouse, north of Laura in Queensland, is also suggested as a vantage point. Those near Newman, Western Australia are expected to see a donut-shaped annular eclipse sunrise, while other parts of Australia will see a partial solar eclipse.

From Tennant Creek the eclipse will begin at 6:55am. reach its zenith at 8:07am and end at 9:33am.

Regions of Australia outside of the main eclipse path will see a partial solar eclipse – a ‘bite’ taken out of the Sun. The maximum of the eclipse in Melbourne, Sydney and Brisbane can be seen at 8:52am, 8:57am and 8:58am respectively (AEDT). Note that the Sun will not be completely covered, so it is important that you do not look directly into the sun at any time during the eclipse.

How to view an annular solar eclipse

Stuart Ryder from the Australian Astronomical Observatory says that while the annular eclipse is a novelty and a great photo opportunity, it is no comparison to a total solar eclipse.

“That tiny ring of uncovered Sun wipes out the dramatic effect of a total solar eclipse,” says Stuart. “The eye simply adjusts to the fading light over an hour or so, and most people on the eclipse path would not even be aware an eclipse was happening above them if it wasn’t in the news.”

Stuart warns that because it will not be completely covered, the public should not look directly into the sun at any time during the eclipse. The safest way to view the eclipse is to use projection. This involves creating a pinhole in a piece of paper or plastic, which is then attached to a tripod and adjusted until the image of the Sun can be seen on a screen.

Watching for ring-like shadows on the ground as the sun shines through gaps in leaves is also an effective way of viewing the eclipse.

Glow worms in Britain, where to see them

Where to see Glow worms in the UK

Female glow-worms produce a soft light in their tails during early summer nights to attract males.

But the romance is a rushed one – adult beetles survive for just a few weeks and in that time they need to mate and lay eggs to ensure the survival of the next generation.

Once far more widespread than they are today, glow-worms have cast a spell over humans for centuries. Shakespeare mentions them in Hamlet and their soft glow on mid-summer nights must have seemed like a scene from a magical world.

Endangered regent honeyeaters freed in Australia

Critically Endangered Regent Honeyeaters released into the wild in Australia

40 captive bred Regent Honeyeaters to be released in Victoria

April 2013. Victoria Department of Environment (DEPI) Senior Biodiversity Officer, Glen Johnson said: “These birds were bred at Taronga Zoo in Sydney and will provide another boost to the Regent Honeyeater population. We’ll be attaching radio transmitters to about 25 of the birds that are being released, and all are fitted with unique colour leg band combinations to assist individual identification,” Mr Johnson said.

Will breed with wild birds

“We know from re-sightings of previously released birds that the captive bred Regent Honeyeaters can successfully breed with and recruit new fledglings into the wild population. Each time we find another captive-bred bird in the wild we learn a bit more about how they are adapting and behaving.”

“The transmitters have been specially adapted for Regent Honeyeaters by Dean Ingwersen, BirdLife Australia‘s National Regent Honeyeater Recovery Co-ordinator and the team at Taronga Zoo. We will be working with skilled volunteers to track these transmitters and identify individuals based on the unique colour band combinations.”

Nomadic birds

Dean Ingwersen said: “Regent Honeyeaters, like other species of honeyeaters, rely on flowering events in our forests for their food, so they are relatively nomadic and can travel large distances. This makes them a difficult species to study particularly when there are so few of them. Once again though, this project highlights the value of releasing captive-bred birds and of colour banding as a research and monitoring tool,” Mr Ingwersen said.

“There’s so much we are still learning about Regent Honeyeater movements and habitat requirements and each detailed sighting report adds to our knowledge about individual birds and the species.”

Black swan and coots


Black swans are originally from Australia. However, there are feral birds in Europe as well.

Two coots seem a bit apprehensive about the feeding black swan. Maybe it is too close to the coots’ nest?

Good koala news from Australia

A Thirsty Koala Returns and Sneezes

Feb 27, 2009

South Australia has had a three-year drought and as a result eucalypt leaves lose much of their moisture. Koalas normally get enough water from eating leaves but lately it’s been too hot so koalas have been coming to homes looking for water. This wild koala first came to our house during an extreme heat wave (see A Thirsty Koala). Three weeks later it got hot again and he came back looking much more lively.

From Queensland University of Technology in Australia:

World-first research will save koalas

The “holy grail” for understanding how and why koalas respond to infectious diseases has been uncovered in an Australian-led, world-first genome mapping project.

The joint undertaking between QUT (Queensland University of Technology in Brisbane, Australia) and The Australian Museum has unearthed a wealth of data, including the koala interferon gamma (IFN-g) gene – a chemical messenger that plays a key role in the iconic marsupial’s defence against cancer, viruses and intracellular bacteria.

Professor Peter Timms, from QUT’s Institue of Health and Biomedical Innovation (IHBI), said the IFN-g gene was the key to finding a cure for diseases such as Chlamydia and Koala Retrovirus (KoRV), currently threatening the vulnerable species.

“We know koalas are infected with various strains of Chlamydia, but we do not know why some animals go on to get severe clinical disease and some do not,” Professor Timms said.

“We also know that genes such as IFN-g are very important for controlling chlamydial infections in humans and other animals.

Identifying these in the koala will be a major step forward in understanding and controlling diseases in this species. “

The research team – made up of Professor Timms, Dr Adam Polkinghorne, Dr Ana Pavasovic and Dr Peter Prentis from QUT; The Australian Museum; veterinarians from Australia Zoo and the Port Macquarie Koala Hospital; and bioinformaticians from Ramaciotti Centre and UNSW – have sequenced the complete transcriptome from several koala tissues.

Dr Polkinghorne from QUT’s School of Biomedical Sciences said data sets from immune-related tissues of Birke, a koala who was euthanised following a dog attack, have revealed a wealth of information about the species’ immune system including the sequences of at least 390 immune-related genes.

“Virtually nothing is known about the immune system of the koala and the absence of information has been a major hinderance to our efforts to understand how Chlamydia and KoRV infections lead to such debilitating disease in this native species,” he said.

Since finding the ‘holy grail’ the QUT team has developed a molecular test to measure IFN-g expression in the blood of healthy and diseased koalas, which has already been applied to a small group of wild koalas taken to the Australia Zoo Wildlife Hospital suffering ocular and reproductive tract disease.

The results will allow researchers to pull apart the complex immune response to better understand how to successfully treat and immunise the vulnerable koala population.

The genes, which only represent about 1.8 per cent of the total set identified in the tissues, were involved in B cell and T cell activation and antigen presentation – key components of the adaptive immune response suggesting that koalas have the capability to protect themselves against microbial pathogens, such as Chlamydia.

Professor Timms’ team, who are currently trialling a Chlamydia vaccine for koalas in South East Queensland, said the koala transcriptome data also provided evidence that the KoRV virus’s genes were not just circulating in the blood, but were also fused to some of the animal’s own genes.

“By analysing this information we should be able to determine if KoRV is sitting harmlessly in these koalas or if it’s potentially triggering cancer or resulting in mild Chlamydia infections becoming a serious clinical disease,” Professor Timms said.

The finding will also help researchers understand why Queensland and New South Wales koala populations have been crippled by the spread of Chlamydia while Victorian populations are much less unaffected.

The project will also aid the conservation of other Australian wildlife, with the team of researchers revealing that the majority of koala sequences shared similarities to that of the Tasmanian Devil.

“While this finding alone is not that surprising, it does show that the immune genes of marsupials are fairly closely related,” Dr Polkinghorne said.

“This promises to benefit gene discovery and the development of immunological tools that will help us to fight diseases in our other threatened and endangered wildlife species.”

While the consortium already contains more than 12 scientists, veterinarians and bioinformaticians, Professor Timms said the team had only scratched the “tip of the iceberg”.

“The task is much larger and will require many more people to assist with analysing the data,” he said.

“Funding to date has resulted in a rich koala genetic bank, but it will fall short if we are to use this data to answer key koala survival questions.

“It is planned to expand the consortium and hold a workshop to develop the best approaches to analysing the data and hence ensure the continued survival of this iconic species.”
