Abstract

In 2019 the nine ACT Wedge-tailed Eagle territories we check each year fledged 1.11 young per territory, with three nests fledging twins. ACT Little Eagle breeding success in 2019 was much lower, at 0.30 young per territory, and attributed to drought (Rae et al. 2019). We suggest that drought is not the only cause of low breeding success in ACT Little Eagles, and that Little Eagle productivity will remain low after the drought lifts. Wedge-tailed Eagle productivity remains high, and they continue to rely on a mix of native and exotic prey. A just-fledged juvenile ranged to the southeast of Canberra, then west into Namadgi and New South Wales, then north of the ACT near Wee Jasper.
