Colours of the Crimson Rosella parrot reveal a deadly secret
The crimson rosella parrot are [sic] immune to Beak and Feather Disease
The vibrant colours of Australia’s Crimson Rosella parrot might not in fact be quite as they seem. The colours covering its feathers could be the result of a virus that is known to kill other species.
A research team from Deakin’s Centre for Integrative Ecology (CIE) and School of Medicine carried out an eight-year study of the Crimson Rosella and subspecies across New South Wales, Victoria, and South Australia.
The Beak and Feather Disease Virus that the Crimson Rosella carry around so proudly in the colour of their feathers is surprisingly deadly in other parrot species. As such, the Australian Government have listed the Beak and Feather Disease Virus as a key threat to biodiversity under the Environment Protection and Biodiversity Conservation Act 1999. Justin Eastwood, Deakin CIE PhD student who worked on the project, explains: “The virus is only found in parrots; it’s no danger to humans, but the danger it presents to parrots seems to vary from species to species and it can be pretty nasty.”
The results, which were published in Proceedings of the National Academy of Science USA journal, could have important implications for managing disease in Australia’s unique wildlife. Project author and CIE researcher Dr Mathew Berg explains, “Our research results are not only good news for Crimson Rosellas, but we now have a good model species with which to study the disease, which is extremely important if we are to minimise its impact on the world’s parrot population.”
The research team aim to better understanding how disease and wildlife interact and co-evolve, and will be working with Zoos Victoria, the Geelong Centre for Emerging Infectious Disease, Charles Sturt University and Biosecurity Victoria to investigate disease ecology and conservation in Australian parrots.

Cockatoos learn to make and use a tool

Zoologger: Cockatoos learn to make and use a tool
03 September 2014 by Michael Marshall
“Drat, I’ve dropped my nut. It’s fallen out of my cage and I can’t reach it through the bars. What to do, what to do…
“Ooh, what’s Figaro up to? He’s got the same problem… He’s got a piece of wood and he’s breaking off a strip from it, oh and now he’s using it to pull the nut back into reach. I’ve got to try that… Right, got the strip, now to rake that nut in. Yes… Yes… Got it!”
This is a train of thought that most humans could pull off fairly easily, but the majority of animals couldn’t even attempt it. Not so the Goffin cockatoo, a popular pet bird that is proving to be surprisingly quick-thinking. After a lone Goffin cockatoo figured out how to make and use a simple tool, others have learned the same trick by watching him.
Give me my nut!
Goffin cockatoos are very intelligent. Last year it emerged that they can do sequential problem-solving: that is, complete a challenge in which a number of tasks have to be carried out in the right order.
The cockatoos were able to unpick a lock that had three elements. Only once the first element had been opened could the second one be opened, and only after that could they open the third. Five birds managed this with guidance or practice, but one pulled it off unassisted (PLoS One, doi.org/m5q).
Then there are the tools. In 2012, Alice Auersperg at the University of Vienna in Austria and her colleagues saw a captive male Goffin cockatoo called Figaro use a stick to try and retrieve a pebble that had fallen out of his cage. He didn’t succeed, but it suggested he knew how to use the stick as a tool.
So they presented him with a nut that was just out of reach beyond the bars of his cage and a large piece of wood. Figaro bit a large splinter out of the wood and used it to rake in the nut. He did this repeatedly (Current Biology, doi.org/vfr).
Do what I do
Now other Goffin cockatoos have picked up the trick, showing that they can learn from each other. Auersperg’s team allowed six cockatoos to watch Figaro use his splinter, while another six were shown control demonstrations in which either the tool or the food were made to move in a Figaro-like way using magnets.
Of the six birds that saw Figaro at work, three could then pick up and use a splinter to retrieve a nut – and two of these even worked out to make a splinter themselves by chewing one off a larger chunk of wood. None of the control birds managed to retrieve the nut.
The successful birds didn’t imitate Figaro’s technique, however. Instead of the raking motion he used, they used a sideways flick. This suggests they understood that the tool could be used to obtain the nut, and then used trial-and-error to figure out how.
Curiously, the three birds that learned how to use the tools were all males, and those that didn’t figure it out, even after watching Figaro many times, were all female. Given the small sample size that could just be a coincidence, but Auersperg says it could reflect a real difference. “I think the males are probably better at problem-solving,” she says. “They have to supply the females at the nest,” giving them an extra incentive to wise up.
It’s not clear why the cockatoos are so innovative, says Auersperg, but it may be because they live on small islands. “They are in a special situation with unpredictable resources,” she says, and that may have forced them to get smart. So far there are no reports of cockatoos making or using tools in the wild, but Auersperg says they haven’t been studied much. “Whether they use tools or not in the wild is the big question,” she says.

New population of Critically Endangered Parakeet Found in north-east Brazil
By Martin Fowlie, Tue, 12/08/2014 – 09:29
A team of young conservationists in Ceará state, north-east Brazil, has discovered a small population of five Grey-breasted Parakeet Pyrrhura griseipectus. Less than 200 of these parakeets are known to survive in the wild – all in Ceará state. These rare birds are listed as Critically Endangered by BirdLife on the IUCN Red List and face immediate threats such as trafficking for the pet trade and habitat destruction. The newly discovered birds represent the third remnant population of 15 populations which were previously known to exist – the other two existing in Serra do Baturité and Quixadá.
The team, employed by Brazilian NGO Aquasis, was granted a Conservation Leadership Programme (CLP) Future Conservationist Awardin 2012. CLP funding allowed the team to conduct several research expeditions with the aim of finding new populations and improving knowledge about the parakeet’s range.
“Last year, as part of our CLP-funded project we found clues suggesting the presence of this species in an isolated mountain, and it was only in March that we were able to confirm and document the finding”, said Fabio Nunes, project leader. “This discovery could be a new hope to add to the existing conservation efforts led by Aquasis and its partners.
Usually, the Grey-breasted Parakeet lives in tropical forests, nesting inside tree hollows. Yet on this occasion, the five individuals were found in a nest located in a small cavity on top of a rocky mountain, above dry vegetation known locally as Caatinga.
The discovery of new populations is excellent news, but the Grey-breasted Parakeet faces an uphill struggle. Having been left in isolation for so long, the genetic make-up of the new population may be different enough to suggest that uniting populations may be problematic and risky.
The team is now writing a scientific paper to emphasise the importance of this discovery for the survival of the Grey-breasted Parakeet. Future conservation efforts will focus on environmental education, and direct species and habitat conservation activities led by Aquasis and supported by CLP, BirdLife International and other donors.
Leiden parakeets get names and numbers
Leiden – Tuesday, July 22, 2014, 12:02
Chris de Waard
Already 85 wild parakeets in Leiden have recently received medals around their necks. Researcher Roland Jonker of the Center for Environmental Sciences of Leiden University wants the ‘Parakeets by numbers‘ project to map how the Leiden parakeet population evolves: “We would really like to know where the birds go, we are also curious about the size of the population and how long the Leiden parakeets live.”
The parakeets’ medals have unique letters and numbers, so the parakeets are easily recognizable. It is estimated that in and around Leiden approximately 850 ring-necked parakeets live. So by now about ten percent have clearly visible badges. Jonker hopes that from now on Leiden people will report back massively parakeets with medals by making pictures of them and posting these to the research project’s Facebook page. As a reward, people who rediscover a parakeet may name that bird.
The medals do not hinder the ring-necked parakeets, according to Jonker. Last year a few parakeets got ‘collars’ and when they were caught again later, it turned out they had not been harmed by them.
“Parakeets by numbers” is a joint project of the Center for Environmental Sciences (CML) of Leiden University and City Parrots in collaboration with the Bird Migration Station and Waarneming.nl.
This research project chose medals, not leg bands, for parakeets; as with the numbers, the birds do not have to be caught again to read letters and numbers, causing less stress for the birds.
