528:. The eggs are pale blue and speckled, about 4.7 × 3.6 cm, and the normal clutch is three or four. Incubation lasts about 28 days, and young fledge 42 days after hatching. Egg survival has been measured at 28% and nestling survival at 40%; storms that destroy nests are an important cause of losses. Based on observations of family groups, only two young normally fledge. Unlike most heron species, whistling herons care for young after leaving the nest; juveniles beg for food by hissing with their wings drooped.

Because it roosts in trees, it particularly likes regions where open areas are mixed with woodlots. It has no objection to human-altered habitats such as pastures and roadsides, and it often perches on fenceposts.
