Hi all,

The yellow colouring of the green feathers is typical of a few diseases. Psittacine Beak and Feather Disease (PBFD) causes patches of yellow but the young Rainbow Lorikeets affected are usually called "runners" because they cannot fly. If you saw these up in a tree in a family group they could probably fly. Liver disease causes green feathers to turn yellow and can be caused by nutritional deficiencies. It can be caused by seed-only diet with no fruit or vegetables in captive birds. In the wild with a family I think liver disease is most likely in an individual. I'm doing a bird medicine course this year and researching questions brought up on Birding-Aus is becoming an interesting challenge.
