First cassowary in space


Karl, the flightless cassowary, was launched into space from beyond the Black Stump in New South Wales on 8 March 2015. He reached 34,780m above the earth, a record for the high altitude ballooning team and thoroughly enjoyed his first solo flight (he has travelled by Jetstar before).

Karl is the mascot for World Cassowary Day which highlights the plight of the endangered southern cassowary. World Cassowary Day will be held at Mission Beach on Saturday 26 September 2015.

Many thanks to Paul Webster from Kuranda Conservation for arranging the space flight. You can learn his love for the cassowary and the planning for the flight at Space cassowary.



How many cassowaries are there in the Wet Tropics?

The Wet Tropics is home to about 4,400 cassowaries, with a minimum of five percent being the year’s youngsters. The figure is based on several years of monitoring and DNA analysis by Dr David Westcott and his team of researchers at CSIRO under the National Environmental Research Program.

Their Wet Tropics surveys  covered 1886 kilometres and 156 transects. They recorded 1444 cassowary signs (dung, feathers, tracks and sightings). They also did 170 surveys of focus sites and recorded 296 signs of cassowaries. The DNA of 435 sub-samples was analysed from 134 different dung samples.

What do the population numbers mean for cassowary conservation?

  • The population estimate is consistent with the upper range of previous estimates undertaken 20 years ago.
  • While these cassowary population numbers are larger than have been often quoted, they are still small enough to place the cassowary at risk from chance events such as cyclones, genetic effects, and increasingly fragmented habitat.
  • The conservation status of the cassowary remains endangered and populations are likely to decrease if habitat fragmentation worsens and cyclones become more intense or more frequent with climate change.
  • Future investment in cassowary management should focus on cassowary habitat protection and connectivity.
  • A regular cassowary monitoring program (for local focus sites and the Wet Tropics region) is essential to track population trends and life histories.
  • Cassowary monitoring with Traditional Owners in Cape York should be established to survey the increasingly fragmented populations in areas such as the McIlwraith Range.

Inside the cassowary’s casque


Scientific American published Inside the cassowary’s casque by Darren Naish on its blog on 15 February 2015.

The article discusses the evolution of the various cassowary species and the anatomy of the cassowary casque and how it may be used. It emphasises that we still have a lot to learn about all these facets of cassowary research.

The Mission Beach Cassowaries website and  Facebook page offer a wealth of information about cassowaries. They collect daily information about local birds and their movements and behaviour. The site has over 900 members who can contribute stories, sightings and photos. Cassowary sightings and incidents are recorded and mapped to help us understand more about their behaviour and promote their conservation.

Mission Beach Cassowaries plays a major role in community education and participation in cassowary conservation. It also contributes to local government planning and campaigns to prevent further cassowary deaths from road accidents and dog attacks.

Visit the Mission Beach Cassowaries website for more information and join in the discussions on its Facebook page.
