Scientific publication Local and regional movements of the Australian White Ibis Threskiornis molucca in eastern Australia

  • Feb 9, 2012

Little is known about the movements of Australian birds. Information is particularly scarce on large, aquatic birds, which are usually difficult to access and handle. Their movements are also often complex, and therefore difficult to identify. Here we present data on the local and long distance movements of the Australian White Ibis Threskiornis molucca, a highly mobile bird, which as many other waterbirds, continues to decline in its traditional ranges in inland Australia. At the same time it has invaded coastal urban environments, where its high abundances cause many problems and require management. Our analysis of past and present banding studies reveals that Australian White Ibis travel throughout the urban environment and visit landfills, where they forage in large numbers. They also conduct long distance movements, which lead birds from breeding sites in south-eastern Australia along the eastern coast to regions further north (Queensland and Papua New Guinea). Young birds return to their hatching site, when sexually mature. Their preferences for landfills, high mobility, complex movements and current decline in inland Australia need to be considered, when developing and implementing management strategies for Australian White Ibis and ecologically similar birds. ...

Article Reddening in our Ibises - Part 3: What does a wild red ibis eat to be red?

  • Jun 20, 2010

Wild birds are not administered artificial products. They still have a beautiful red colour. In the four studies that have taken place in the wild, it appears that the birds perfect their colours from crustaceans, insects and fish. Of course it is impossible for us to feed it every day. However, keep in mind that the daily feed what we provide to our many birds also contains carotenes: Maize, linseed, fish (flour), shrimp (flour), spirulinae, ...

Article Reddening in our Ibises - Part 2: Dose administration carotenes

  • Apr 11, 2010

In Part 1 we learned that carotenes are responsible for the reddening of our birds. That is the reason why we carotenes, in the form of canthaxantine, extra to administer the diet of our birds. What is now the ideal dose to deal with the birds? Nobody knows what the perfect dose is, so we look at what dose zoos feed their animals. Finally, we compare this with the maximum dose that people may have. ...
