11001-72717 Kea or mountain parrot (Nestor notabilis) a wild female 'golden' kea. The golden-yellow coloration is due to the mutation ino - a strong qualitative reduction of melanin. Among parrot breeders, this mutation is known as lutino, because of the predominant yellow colour. In ino mutations, melanin synthesis scarcely occurs, resulting in the yellow psittacin becoming clearly visible. Ino is a recessive and sex-linked mutation, most wild yellow individuals are typically female.*
11001-73604 Red-crowned parakeet (Cyanoramphus novaezelandiae novaezelandiae) turquoise mutation. This museum mounted speciman is at least 120 years old. It is the only turquoise mutation of a wild kakariki ever documented, it was collected in Southland in the 1800's. The remarkable colour is caused by an inherited recessive mutation that results in the birds inability to produce yellow pigment. The red colour on the crown and eye stripe is also affected and appears as a salmon colour instead. This colour mutation, incorrectly referred to as blue or even aqua, is most accurately termed ParBlue *
