This year three chicks appeared in early October. To date they are progressing nicely.
From their earliest days, the chicks make a variety of sounds depending on their activities.
The feeding sound is not unlike that made by a group of young chickens.
The sounds of Cassowary chicks feeding. The enthusiasm of the chortles is directly related to the quality of the food.
The Cassowary distress call.
If the chick gets out of sight of his father, who looks after the chicks for their entire young lives, it produces a sound like the above. If it is really distressed, the call is much more strident and much much louder. At no time have I ever seen the father rush to the aid of a supposedly distressed bub. (However, I have not tested this by grabbing one of the chicks!!).
Soon the father Cassowary will somehow decide that it's time for the chicks to be on the their own. He will drive them away and the distressed chicks will be heard calling throughout the rainforest.
They will just stand around calling and wondering what has come over their father. Just a day before he was a caring and protective creature and now he has completely changed.
As adults Cassowaries are generally silent. I have heard the male only make a booming sound that carries for a great distance through the undergrowth. I've not heard the female make a similar sound. Both sexes produce a sort of hiss when they are around one another.
