Rainbow Lorikeet preening tail feathers, Brisbane Australia   //   Rainbow Lorikeet - Psittacidae: Trichosurus haematodus. Length to 30cm; wingspan to 45cm; weight to 150g; Found in northern and eastern Australia from the Kimberley Region in northern Western Australia (Red-collared Lorikeet) to eastern South Australia. Occurs in forests, woodlands, heath, and rural and urban areas. Aviary-escapees are established in many towns and cities. Widespread with many subpsecies - often with a different name - from eastern Indonesia through New Guinea east to Vanuatu and New Caledonia, north to the Philippine Islands.   Some feathers change colour when a Rainbow Lorikeet is wet - the differences in colour types- either pigment-related or structure-related cause this. In these lorikeets the colour of predominantly green feathers, such as on the wings and back, comes mainly from micro-structures on the feather barbules that interfere with light wavelengths, changing one colour to another; When molecules of water in the rain fill in these micro-structures the green colour alters to brown. Pigment-based feathers are not affected, unless they have both pigmented and structural attributes. When dry these birds will return to their normal gaudy plumage. IUCN Status: Least Concern.  //Eric Lindgren//
