Sulphur-crested Cockatoo

A large, iconic white parrot with a distinctive forward-curving yellow crest, dark beak, and grey feet. It is known for its incredible intelligence and loud, raucous screech.

Predominantly bright white on both surfaces, featuring a characteristic pale yellow or lemon-tinted wash on the underside of the inner vane

Densely interlocked pennaceous barbs throughout most of the vane; plumulaceous (downy) barbs present at the base for insulation

The rachis is thick, white, and slightly curved. Barbs are tightly packed and angled consistently toward the tip

Smooth and firm texture with a slightly chalky or matte finish due to powder down; non-iridescent

Wing; the asymmetry indicates it is a remex (flight feather) from either the secondary or inner primary section

Pure white plumage with a subtle yellow wash on the underside of the wings and tail; thick, sturdy white rachis

Woodlands, rainforest edges, scrublands, and increasingly common in urban parks and suburban gardens

Native to Australia, New Guinea, and some islands of Indonesia; introduced populations in New Zealand and Singapore

Acts as a seed disperser and occasional pest of cereal crops; occupies a high-level herbivore/granivore niche

Yellow-crested Cockatoo (Cacatua sulphurea) which is smaller; Galah (Eolophus roseicapilla) which has distinct pink and grey coloration

Sulphur-crested Cockatoos can live up to 70-80 years in captivity and are capable of complex problem-solving and rhythmic movement to music

Significant in Australian Indigenous culture; historically and currently popular in the pet trade, though wild harvest is strictly regulated

Look for these feathers near large eucalyptus trees or roosting sites; the 'powder' feel is a major diagnostic clue for cockatoo feathers

The feather appears in good condition, likely naturally molted given the intact calamus and minimal wear on the vane edges
