Brown and Striated Thornbills were banded at New Chums Road in the Brindabella Range,
Australian Capital Territory from 1961 to 1982. Both species appeared to be sedentary once they
established territories although there is some indication that the territories of Striated Thornbills were
held by small groups. The mean annual survival rate of adult Brown Thornbills was 59 per cent and
Striated Thornbills 68 per cent. The oldest Brown Thornbill recaptured was 13 years and 7 months
and the oldest Striated Thornbill was 15 years and 7 months.
