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

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

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

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