The Australian brush-turkey belongs to a family of birds--the megapodes--that has evolved a breeding strategy like no other bird group.
Since brush-turkey chicks don't initially form groups with adults, they are not at risk of offending adults, so do not need to `hide' such behaviours.
Goth investigated predator recognition in brush-turkey chicks to see how they manage once they leave the mound.
Goth thought that chicks might take note of the warning calls of other bird species in lieu of parental calls, since brush-turkey adults, unconventional to the end, do not utter any alarm calls of their own.
The experiment showed that in brush-turkey chicks the alarm calls of other rainforest birds have indeed replaced those of absent parents.
Without parents to show them where and what to eat, how do newly hatched brush-turkey chicks find and identify food?
Some of these pre-existing behaviours change as the brush-turkey ages and learns from experience.
