Emu

The emu is the second-tallest living bird by height, reaching up to 1.9 meters. It is a large, flightless ratite with powerful legs, shaggy grayish-brown plumage that helps camouflage it in dry scrub, and a vestigial wing structure hidden beneath the feathers.

Dark grayish-brown to blackish coloration with a pale yellowish-horn colored rachis, uniform throughout without complex banding

Plumulaceous (downy and hair-like) with elongated, disconnected barbs lacking functional interlocking barbicels, possessing a distinct double-shaft (aftershaft) feature typical of ratites

Coarse, hair-like, flexible, and matte, lacking the stiffness and smooth interlocking surface of flight feathers

Extraordinarily long, hair-like barbs; prominent double shaft (aftershaft); lack of interlocking vane structure; coarse grayish-black texture

Open country, including eucalyptus forests, scrublands, savannas, and semi-arid grasslands across mainland Australia

Endemic to mainland Australia, introduced to Tasmania and various offshore islands; highly adaptable and nomadic

Acts as an important seed disperser for many native Australian plants by consuming fruits and excreting seeds over long distances across varied terrains

Other ratites such as Ostriches, Cassowaries, and Rheas, though emu feathers are uniquely hair-like and feature dual shafts of nearly equal length

Emus can run at speeds up to 50 km/h (31 mph), have unique double-feather shafts where two feathers grow from a single quill, and the male incubates the large dark green eggs while fasting for nearly two months.

Fair condition, showing some wear and slight separation of the barbs due to environmental exposure on the beach
