The Brolga is a species of crane found in Australia and New Guinea. They are also known as Australian Cranes or by their former name: Native Companion.
Brolgas are non-migratory, but make seasonal movements depending on rain levels. Their preferred habitats include freshwater marshes and lagoons, tidal pools, and mangrove swamps. They may also be found in irrigated cultivated farmland.
Brolga pairs mate for life. Bonded pairs perform synchronous trumpeting calls as part of their courtship or pair-bonding each breeding season.
Details & Statistics
The Brolga is listed as Least Concern on the IUCN Red List and was last assessed in 2012 by BirdLife International. This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size may be moderately small to large, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
