Variation in the three contact calls of the Silvereyes in the Brisbane region were compared to
those of a sedentary subspecies in the Capricorn-Bunker group of islands in the Great Barrier Reef.
Brisbane males within a flock or holding territories in the same area used the same variable call,
whereas the Capricorn subspecies call showed no individual consistency. This difference between the
subspecies was discussed in relation to their ranging behaviour.
