Cook Islands fruit-dove  (Ptilinopus rarotongensis)

This small, beautifully coloured pigeon is found only on two small islands in the South Pacific Ocean. It has a bright magenta crown, against a pale grey head, chest and upper back. The Rarotonga subspecies also has a yellow belly with a bright magenta patch, whilst the Atiu subspecies has a pale greenish-yellow belly. The rest of its plumage is mostly green, apart from a yellow edging on the wing-feathers, and it has a pale green-brown bill (2) (3) (4). The male and female are similar in appearance, but juveniles are distinguished by the lack of red patches on its crown and belly (2). The calls of this bird, which are haunting coos, differ slightly between the two island populations.
