The Brolga is a large grey crane, with a featherless red head and grey crown. The legs are grey and there is a black dewlap under the chin. The Brolga's call is a loud trumpeting 'garooo' or 'kaweee-kreee-kurr-kurr-kurr-kurr-kurr-kurr', which is given in flight, at rest or during courtship. The Sarus Crane, G. antigone, another species of crane found in Australia, can be identified by its dull pink legs and the red of its head extending down the neck. Both species are similar in height (up to 1.3 m), with females shorter than males.
