A dingo captures a swamp wallaby in the surf on Fraser Island's Seventy-Five Mile beach. Warning: some viewers may find the video distressing. Mark Furler

 
RARE and dramatic footage of a dingo attacking a swamp wallaby in the surf on Fraser Island has been captured by a ranger-guide hosting a tour.
Fraser Explorer Tours ranger-guide Hayden Webber was taking tourists on a Cool Dingo bus tour last week when he shot the amazing video of the dingo capturing and killing the wallaby in small waves near the shore at Seventy-Five Mile Beach.
"It's just nature folks," he told the tour group as they watched the wallaby struggle and try to jump away from the dingo.
"I know it's not very nice to see folks but that is just life, it's just nature."
Warning: some readers may find the video distressing.
Hayden and his bus load of 33 international passengers from Germany, Austria, Switzerland, Korea, Taiwan and the United Kingdom were on the second day of their Cool Dingo tour and were driving just north of The Pinnacles coloured sands about 9.30am on Thursday when Hayden noticed the wallaby in the water.
"I said to my passengers: 'hey there's a wallaby in the water'... and they all grabbed their cameras and, as you can imagine, there was lots of excited chatter in the bus," he said. 
"I knew when we stopped, that it was unusual to see the wallaby on the eastern beach - they're normally found in the swamps on the western side of the island - let alone in the water, so I immediately started scanning the dunes for dingoes... and sure enough an old experienced male came bounding out of the dunes... so I leapt for my camera and let it roll.
"Whilst initially there were gasps from some of the girls in the group about watching this scene unfold, I explained that it may not be all that nice to watch, but that it was just nature in action.
"When we talked about it later that day, everyone said they were glad they had seen the dingo doing what nature intended.
"It's actually not unheard of to hear about this sort of hunting behaviour - where dingoes shepherd their prey to the water's edge to make it easier to catch.
"Our fraternity of Fraser Island Tours guides can recall one instance from a long time ago where a similar thing happened - but it is certainly unusual to occur in front of a bus load of passengers.
"Add to this the fact that I've been guiding on Fraser Island for a little over six years and have only seen four wallabies in that time - and you'll start to appreciate how rare and exciting this was for me.
"I have never seen this before and I never expect to see it again."
Head ranger Colin Anderson said all Fraser Explorer Tour guides conducted talks on dingoes and dingo behaviour and on the animals of Fraser - including swamp wallabies - so it was fascinating for international guests and friends on social media sites to see normal hunting behaviour in action.

Bigger and brainier: did dingoes kill thylacines?

May 3, 2012


*This image is copyright of its original author

Skulls of two thylacines and a dingo from the Nullarbor in Western Australia. A thylacine, thought to be female (left); a male thylacine (middle); a dingo (right).

Direct attacks by introduced dingoes may have led to the extinction on the Australian mainland of the iconic marsupial predator, the thylacine, a new study suggests.

A comparison of museum specimens has found that thylacines on mainland Australia were smaller than those that persisted into modern times in Tasmania, and significantly smaller than dingoes. The last known Tasmanian thylacine died in 1936.

Measurements of the head size and thickness of limb bones of the semi-fossilised remains of thylacines and dingoes from caves in Western Australia have revealed that, on average, dingoes were larger than thylacines.

“In particular, dingoes were almost twice as large as female thylacines, which were not much bigger than a fox,” says ecologist Dr Mike Letnic, an ARC Future Fellow in the UNSW School of Biological, Earth and Environmental Sciences, who led the study with colleagues at the University of Sydney. The findings are published in the journal PLoS One.

There has long been debate as to what caused the extinction of the thylacine from mainland Australia, Dr Letnic notes. Because Tasmanian thylacines were much larger than dingoes, direct confrontation between the two species was discarded as a hypothesis for the thylacine decline.

Another hypothesis is that competition between the two species may have been the cause: however, competition is not thought to be a strong driver of extinction. More recently, some authors have suggested that people caused the extinction of the thylacine through direct hunting or suppression of prey.

“We were aware of old reports that mainland thylacines were smaller than Tasmanian ones,” says Letnic. “Modern ecological studies show that larger predators frequently kill smaller predators, so we decided to test the hunch that dingoes were actually larger than thylacines and caused their extinction by killing them in direct confrontations.

“We also measured the brain size of both species and found that dingoes also had much bigger brains than thylacines, so they may have outwitted them, too.”

Dingoes appear to have had a dramatic impact on the ecology of Australia when they first arrived between 3,500-5,000 years ago, probably introduced by human seafarers, and likely also caused the extinction of the Tasmanian devil from mainland Australia (devils are still found in Tasmania, which does not have dingoes).

“However, recent studies suggest that dingoes now play an integral role in maintaining healthy balanced ecosystems by limiting the populations of herbivores and smaller predators, a role that was once filled by the thylacine,” says Dr Letnic.

I have caught fleeting observations of the dingo-like dogs ( feral or wild ) living in the swampy country where Georgia meets South Carolina. The real "Old Yeller."

These are sad cases :/ And not the first time, something what can´t be ignored if camping in Australia.

Indeed. There was a very famous case a few decades ago, where the iconic line "a dingo ate my baby" is burned into the minds of many. Truly predators to be wary of in the outback.

My favorites extant canid

‘A juvenile Australian dingo licks the face of its pack leader in typical submissive behaviour. This behaviour is crucial to maintaining hierarchy in a dingo pack; to not show respect to a pack leader would end in the young dingo being disciplined by not only the leader but the whole pack. This image of wild dingoes was captured in an area of the Great Sandy Desert in western Australia where this group live on the edge of a remote gold mining operation. Interestingly, the mining operators have put strategies in place so as not to allow the dingoes to obtain food and water to make sure the dingoes remain reliant on their own survival skills.’ - @gaz_meredith_images


Gary Meredith is a wildlife photographer based in western Australia. He spends his time photographing wildlife that has adapted to human-modified environments, capturing unseen behaviour of birds in the western Australian desert as well as photographing and advocating for the protection of Australia’s native canid, the dingo. In #WPY56, he was highly commended in the Urban Wildlife category for his characterful portrait of two possums."

Ecosystems on either side of the dingo fence have shifted to alternate states with and without dingoes. Small mammals, rabbits and ground nesting birds prosper with dingoes. Kangaroos, foxes, cats & woody shrubs thrive where dingoes are rare.


Two alternate states: shrub, bird and mammal assemblages differ on either side of the Dingo Barrier Fence

ABSTRACT

The 5500 km long dingo barrier fence (DBF) is a boundary at which the goal of dingo control programs shifts from management to elimination. Since 1980 ecologists have used the discrepancies in dingo densities across the DBF to study the ecological role of Australia’s largest terrestrial predator.
We used drone imagery, ground based shrub and tree counts, and camera trap footage to test our hypothesis that there are alternate states in plant, bird and mammal assemblages on either side of the DBF. We found that shrubs and trees were twice as dense where dingoes were rare, and 28 % of shrub and tree species, 78 % of mammal species, and 14 % of bird species recorded were significantly more likely to occur on one side of the DBF than the other.
We provide the first comprehensive snapshot of how flora and fauna assemblages differ across the DBF. This study adds to literature demonstrating that the removal of the dingo has led to profound shifts in the shrub, mammal and bird assemblages in arid Australia. Any expansion of dingo control in arid Australia must be considered against the far-reaching consequences for ecosystem assembly associated with the removal of a top predator.

Pelage variation in dingoes across southeastern Australia: implications for conservation and management

Abstract

How to manage hybridization and introgression in wild animals is controversial. Wildlife managers and researchers may often rely upon phenotypic variables such as coat colour to inform on ground management decisions. In Australia, dingoes are typically believed to be ginger in colour, and unusual coat colours such as brindle or sable are widely posited to be evidence of contemporary domestic dog hybridization. We carried out microsatellite-based genotyping on 1325 wild canids from southeastern Australia of known coat colour to estimate the extent of domestic dog introgression. A key aim of our study was to examine the relationship between coat colour and ancestry in wild dingoes. We observed that 27.4% of our samples were dingoes with no evidence of domestic dog ancestry whilst 72.6% were dingoes with some domestic dog ancestry. Our data confirm that feral dogs, domestic dogs with no dingo ancestry, are rare in the wild, representing less than 1.5% of the population. There was no coat colour that could distinguish dingoes with or without dog ancestry from each other. Contrary to popular belief, colours such as brindle and patchy were positively associated with dingoes with no dog ancestry and were less common in dingoes of mixed ancestry. A key finding of this work is that coat colour should not be used to assess ancestry in dingoes. Further research is needed to uncover the antiquity, origin and potential adaptive value of these genomic regions. It is possible that this is a similar example of adaptive introgression as has been observed in North American wolves with black coat colour. These data add perspective to global debates about how to manage and conserve enigmatic animal populations in the presence of modern or historical introgression.
