Sulphur-crested Cockatoo (White Cockatoo)

A magnificent large white parrot reaching 50cm in length. Known for its expressive yellow crest, dark bill, and raucous screeching. This feather is a vital component of its powerful, flapping flight and gliding sequences.

Pure white across both vanes. The underside (ventral) may show a subtle yellowish hue, characteristic of the species' wing lining. The rachis is a pale, translucent cream-yellow.

Densely interlocked pennaceous barbs providing a rigid, aerodynamic surface; notable lack of downy plumulaceous structure at the base.

Robust, thick rachis that is slightly curved and tapers toward the tip. Barbs are tightly packed and align at an acute angle to the shaft.

Smooth, slightly stiff, and remarkably clean. The surface has a fine, powdery texture known as 'powder down' which provides water resistance and a matte finish.

Wing, specifically a primary flight feather from the outer wing. The asymmetry indicates its role in generating thrust during flight.

Pure white color, large size, extreme asymmetry of the vanes, and a thick yellowish-white quill/rachis.

Woodlands, rainforest margins, scrublands, and increasingly common in urban parks and gardens where tall trees are available.

Native to Australia (north and east), New Guinea, and Indonesia; widely introduced to parts of New Zealand and various islands.

Functions as a seed disperser and occasional pest of grain crops. They are highly social and act as 'sentinels' for other wildlife with their loud alarm calls.

Yellow-crested Cockatoo (smaller), Salmon-crested Cockatoo (peachy-pink base), and Galah (pink and grey).

The 'powder down' on this feather is produced by specialized feathers that crumble into a fine dust, used by the bird to groom and waterproof its plumage.

Historically used in indigenous Australian ceremonies and adornment. In modern times, often found in 'enrichment' crafts for captive birds, though trade is regulated.

Look for these feathers under tall eucalyptus trees or roosting sites in the morning. Often found alongside smaller, downier body feathers.

Excellent condition. The vane is intact without apparent fraying or 'fault bars'. Likely a freshly molted feather.
