Emu

The emu is Australia's largest native bird and the second-largest extant bird in the world by height. It is a flightless running bird with long legs and a shaggy, grey-brown plumage that helps it blend into the dry Australian bush. Emus have vestigial wings and lack a keel on their sternum. Their specialized double-shafted feathers act as a thermal blanket, protecting the bird from extreme desert heat by trapping a layer of air against the skin.

Deep charcoal grey to blackish coloration near the upper portion and tip, transitioning into a lighter brownish-grey base with pale or whitish shafts. The tips are often sun-bleached to a brownish or tan shade.

Plumulaceous (downy/loose) throughout most of the feather length with completely un-interlocked barbs lacking functional hooklets, giving it a distinctive hair-like or grass-like texture. Features the characteristic emu double-feather structure where two feathers emerge from a single shaft.

Coarse, hair-like, straw-like, and completely soft and flexible without any stiffness of flight feathers. Matte finish with no gloss or iridescence.

Distinctive double-feather structure where two shafts of equal length emerge from a single base, combined with long, hair-like, completely un-interlocked blackish barbs.

Open country, savannas, sclerophyll woodlands, and arid shrublands across mainland Australia, avoiding dense forests and extremely arid deserts.

Endemic to mainland Australia, introduced to Maria Island off Tasmania. Highly nomadic across its range depending on food and rainfall availability.

Important seed dispersers across the Australian landscape, consuming large quantities of fruits and native vegetation and excreting seeds intact over wide ranges.

Other ratites such as Ostriches, Cassowaries, and Rheas, though their geographic distributions and specific feather morphologies differ distinctly.

Emus are capable of running at speeds up to 50 km/h (30 mph) when startled. Uniquely among birds, male emus incubate the eggs and raise the chicks alone, fasting for up to two months during the incubation period.

Good condition; barbs are intact but naturally separated due to the lack of barbules and hooklets inherent to ratite body plumage. Minor tip wear and sun-fading visible.
