Gawarrgay
Gawarrgay is the Gamilaraay and Euahlayi celestial emu, drawn in dark dust from the Coalsack to Scorpius, not in star-to-star lines.
Fuller, Anderson, Norris and Trudgett (2014) record Gawarrgay (also Gawarghoo) as the emu in the Milky Way. The head is the Coalsack under α Crucis. The neck runs through the pointer stars. The body thickens toward Scorpius. The earth emu is dhinawan. Two names keep sky Law and the living bird from collapsing into one cartoon.
The figure changes with the seasons at about 21:00. In April and May it has legs and looks like a female running after a mate, which is when eggs are taken. In June and July the legs vanish and the male sits the nest. By August the neck fades and the body can read as an egg, or as two rings. In November the body sits on the horizon in a waterhole. In high summer it is almost gone, and the waterholes are dry.
