The emu (/ ˈ iː m juː /; Dromaius novaehollandiae) is a species of flightless bird endemic to Australia, where it is the tallest native bird. It is the only extant member of the genus Dromaius and the third-tallest living bird after its African ratite relatives, the common ostrich and Somali ostrich. The emu's native ranges cover most of the ...
Some Australian fossils initially believed to be from emus were recognized to represent a distinct genus, Emuarius, [a] which had a cassowary-like skull and femur and an emu-like lower leg and foot. In addition, the first fossils of mihirungs were initially believed to be from giant emus, [ b ] but these birds were completely unrelated.
The red kangaroo maintains its internal temperature at a point of homeostasis about 36 °C (97 °F) using a variety of physical, physiological, and behavioural adaptations. These include having an insulating layer of fur, being less active and staying in the shade when temperatures are high, panting, sweating, and licking its forelimbs.
Organisms begin as naive individuals and learning allows them to obtain the knowledge they need to adapt and survive. A learned adaptive behavior must have a psychological, as well as a biological, component; without the integration of these two disciplines, behavioral adaptation cannot occur.

The precocial juveniles may also have been an adaptation to predation, and while King Island did not have large carnivores, there was a now extirpated population of very large tiger quolls which could have preyed on emu chicks. If the size of the clutch of King Island emus was large, and not the result of more than one female laying eggs in a ...
Emuarius is an extinct genus of casuariiform flightless bird from Australia that lived during the early Miocene and late Oligocene.It is one of two known genera of emu. [3] There are two known species in the genus, Emuarius gidju and Emuarius guljaruba.
The work above is just one example of an ecomorphology based behavioural study. Studies of this variety are becoming increasingly important in the field. Behavioural studies interrelate functional and eco-morphology. Features such as locomotory ability in foraging birds have been shown to affect dietary preferences by studies of this type. [11]
