Hi Charles,

The separation in the field of the Russet-tailed and Bassian Thrushes is not easy. They can be easily identified in the hand (during banding or when found dead) by measuring the wing and tail and noting the amount and arrangement of the white tongue in the tail. Birds at Pearl Beach are most likely to be the Bassian Thrush but I did band a bird at Tumbi Umbi several years ago that fitted, on measurement, the Russet-tailed Thrush. The best field ID characters are the rump markings and white in the tail. The black edging to the rump feathers is broad and obvious, similar to the back feathers, in the Bassian, and narrower and paler than the back markings in the Russet-tailed. The amount of white showing in the tail is greater in the Russet-tailed. Generally the Russet-tailed is more reddish -brown while the Bassian is olive-brown. The song of the Bassian is more drawn out and is somewhat reminiscent of a Blackbird's song. Russet-tailed songs are of shorter duration and lack the similarity to Blackbird's call. Contact calls, as far as I am aware, are similar in both species being subdued and wren-like.
