Cockatiel

The cockatiel is the smallest member of the cockatoo family, instantly recognizable by its prominent erectable crest and cheerful disposition. Known for their striking facial markings in wild types and varied mutations in captivity, they are social, intelligent, and vocal parrots.

Predominantly white with slight greyish or brownish dusky tinting near the tip, typical of a white-phase or mutation cockatiel body feather

Mixed structure; pennaceous upper vane with partially unzipped barbs and a plumulaceous (fluffy) base with disconnected barbs lacking effective hooklets

Soft, silky, and somewhat loose in texture, matte appearance with a fluffy, downy lower section

Small size, white coloration with subtle grey tipping, delicate white rachis, and a fluffy plumulaceous base characteristic of parrot body feathers

Arid and semi-arid open country of Australia, heavily reliant on water sources, now widely kept globally as a domestic pet

Endemic to the interior regions of Australia; introduced and widely kept worldwide in captivity

In native Australia, acts as a seed disperser and forager in arid grasslands, though captive populations have no local wild ecological impact

Other small parrots, parakeets, or doves, distinguished by the specific size, crest proximity, and distinct white/grey coloration of cockatiel mutations

Cockatiels possess a distinctive yellow crest that reflects their emotional state, standing straight when startled or excited and flattened when angry or resting

Fair to Good condition; some barbs are separated or unzipped along the shaft, showing minor wear typical of a dropped body feather
