Rigid wing-tags for Cockatoos

Between 1970 and 1975, 1 128 Galahs and 685 White-tailed Black-Cockatoos were marked with wing-tags so that the birds could be individually identified without resorting to re-trapping.  Tags have been worn by some cockatoos for eight years and do not appear to have interfered with their behaviour or reproductive success.  Similar wing-tags have been used on Long-billed Corellas, Little Corellas, Red-tailed Black-Cockatoos and Pink Cockatoos.
