FACTOID #53: If you thought Antarctica was inhospitable, think again - its land area is only ninety-eight percent ice. Reassuringly, the other 2% is categorised as "barren rock".
The word incubate in the context of birds refers to the development of the chick (embryo) within the egg and the constant temperature required for the development of it over a specific period. This, in most species of bird is produced by endothermic body heat from the brooding parent, though several groups, notably the Megapodes use the heat generated from rotting vegetable material, effectively a giant compost heap instead.
Climate-controlled incubators are used in industrial agricultural settings and in neonatal care, especially of human infants. Incubators have greatly increased life-expectancy for premature infants.
In economics, an incubator is a set of resources such as physical space, communications tools, investments or human resources intended to promote development of business or technology.
Birds are bipedal, warm-blooded, egg-laying vertebrates characterized primarily by feathers, forelimbs modified as wings, and hollow bones.
Birds respire by means of crosscurrent flow: the air flows at a 90 degree angle to the flow of blood in the lungs capillaries.
Birds possess a ventriculus, or gizzard, that is composed of four muscular bands that act to rotate and crush food by shifting the food from one area to the next within the gizzard.

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 falcons.
