Introducing the Emu - the Great Australian Bush Chook
Emu run through

Professor Graeme Martin, from the University of Western Australia’s Institute of Agriculture, brings us up to speed with the emu.  
In fine feather

Emu feathers are very interesting for several reasons. Emus have no flight feathers and basically retain chick feathers through to adulthood. These are fluffy and are great for insulation against high and low temperatures. Emus have adapted incredibly to thermal environments living in the hot dry rangelands to the snowfields. Indeed, emus forage in the arid zone when the temperature can be as high as 45°all other animals seeking shelter and shade. The shape of the emu’s coat is similar to an umbrella over its back. The solar radiation is absorbed by the interlacing black feather tips, far away from the skin. It only takes a couple of metres per second of wind speed for that heat to be transferred to the air. Because emus never stop walking when they forage they are exposing themselves to enough wind speed to basically remove all of the heat generated from the sun. Emus will probably cope with climate change, with their excellent thermal regulatory capacity. They will, however, have other challenges like the changes in habitats and whether their food will be maintained, even though they are omnivorous. 
The very public private life of male emus

Associate Professor Dominique Blache, from the School of Animal Biology and Institute of Agriculture at the University of Western Australia, describes some of the fascinating behaviour of emus where females definitely rule the roost.
