Breeding
The breeding period is highly seasonal, with eggs being recorded between October and March. Pair-formation amongst groups often beings in October, beginning with both potential parents running in circles with each other. The male then engages in a "dance" flings various objects in the air and then jumps. Eventually, a female from the group and the male appear to "select" each other and both engage in the dance of throwing objects and jumping. After the dance, mating commences in around two weeks.
In a great majority of known nests, two eggs are laid (rarely 1 or 3). Both males are females will incubate, with the male often incubating at night and, during the day, defending the nest territory during the day while the female incubates. The incubation stage lasts around 30 days. The young are able to walk after two days and can swim well shortly thereafter. They are fed primarily by their mothers, who regurgitates food into the mouths. Depending on the growth rate of chicks, the fledging stage has been reported when the young are anywhere from 30 to 60 days old. The young continue to be tended to until the next breeding season, at which time they are chased off by their parents.

Famous quotes containing the word breeding:
“The test of a man’s or woman’s breeding is how they behave in a quarrel. Anybody can behave well when things are going smoothly.”
—George Bernard Shaw (1856–1950)
“Good breeding and good nature do incline us rather to help and raise people up to ourselves, than to mortify and depress them, and, in truth, our own private interest concurs in it, as it is making ourselves so many friends, instead of so many enemies.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“Civility, which is a disposition to accommodate and oblige others, is essentially the same in every country; but good breeding, as it is called, which is the manner of exerting that disposition, is different in almost every country, and merely local; and every man of sense imitates and conforms to that local good breeding of the place which he is at.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
