ABSTRACT Sympatric breeding of Sarus Cranes (Antigone antigone) and Brolga (A. rubicunda) occurs only in northern Queensland, Australia but factors contributing to this unique sympatry are unknown. Large-scale developments currently planned in this region, with potentially major impacts on cranes, create an urgent need to understand the ecological requirements of each crane species. We carried out a multi-floodplain landscape-scale survey during April–May 2017 and derived metrics for several… 
Numbers, distribution and behaviour of Australian Sarus Cranes Antigone antigone gillae and Brolgas A. rubicunda at wintering roosts on the Atherton Tablelands, far north Queensland, Australia
The Atherton Tablelands in far north Queensland is the only currently known concentrated flocking area for Australian Sarus Cranes Antigone antigone gillae . Brolgas A. rubicunda also flock there in
First observations of Australian Sarus Crane Antigone antigone gillae pairs attending three young and the incidence of three-egg clutches in the Brolga A. rubicunda
Clutch-size in gruine cranes is consistently two. Clutches of three eggs are very rare, and records of adults supporting three young even more so. We report two observations from the Atherton
First observation of a Brolga Antigone rubicunda preying on eggs and of ‘water-kicking’ behaviour by Australasian Grebes Tachybaptus novaehollandiae as a nest-defence
We report a novel observation of Australian waterbird behaviour: a Brolga Antigone rubicunda preying on eggs of the Australasian Grebe Tachybaptus novaeholliandiae , the first record of birds’ eggs

Breeding and Flocking:Comparison of Seasonal Wetland Habitat Use by the Brolga Grus rubicunda in South-western Victoria
TLDR
Variable nature of habitats used by the Brolga and the variation in habitat u se cr e at e a ch a ll e ng e for the effective long-term management and conservation of the species are studied.
Recruitment rate of Sarus Cranes (Grus antigone) in northern Queensland
TLDR
Comparison with other crane populations indicates that the recruitment rate is low, but further detailed data are needed to evaluate properly the status of the population.
