Spix's macaw  (Cyanopsitta spixii)

Spix's macaw is the world's rarest bird, believed to have become extinct in the wild as of 2000 (5). This elegant parrot has delicate blue-grey plumage, fading from the bright blue tail and wings to an ashy-blue crown (4). There is an area of featherless, dark grey skin around the eyes. Juveniles are typically dark blue in colour but the skin around the eye is pale (2).
