In the species that incubate, the work is divided differently between the sexes. Possibly the most common pattern is that the female does all the incubation, as in the Coscoroba Swan and the Indian Robin , or most of it, as is typical of Falcon s. In some species, such as the Whooping Crane , the male and the female take turns incubating the egg. In others, such as the Cassowaries , only the male incubates. The male Mountain Plover incubates the female's first clutch, but if she lays a second, she incubates it herself. In Hoatzin s, some birds (mostly males) help their parents incubate later broods. Incubation times range from 11 days (some small Passerine s and the Black-billed and Yellow-billed Cuckoo s) to 85 days (the Wandering Albatross and the Brown Kiwi ). In these latter, the incubation is interrupted; the longest uninterrupted period is 64 to 67 days in the Emperor Penguin . {Link without Title} Some species begin incubation with the first egg, causing the young to hatch at different times; others begin after laying the last egg of the clutch, causing the young to hatch simultaneously. DERIVED MEANINGS Climate-controlled incubators are utilized in industrial agricultural settings and in neonatal care, especially of human infants. The life expectancy for premature infants has increased dramatically thanks to Incubation . REFERENCES
