egg incubation

Egg incubation is estimated to be between five and seven weeks.

However in one recorded case, the egg incubation occurred entirely within a chicken.

Egg incubation: its effect on embryonic development in birds and reptiles.

Egg incubation does not occur until both eggs have been laid, and they are usually incubated one in front of the other.

Chicken egg incubation can successfully occur artificially as well.

Due to ecological changes such as trees growing to shade the nest, this can change the environment into an inadequate location for egg incubation.

Scientists have discovered that the gender of a sea turtle is determined by the temperature of the sand during egg incubation.

Egg incubation is temperature dependent and the period from deposition to hatching ranges from 2 to 22 days.

The off-duty fulmar had returned to relieve his/ her partner for a spell from the shared task of egg incubation.

One of the many conservation efforts being implemented to increase populations at this time is the use of hatcheries for protected egg incubation.

Most avian brood parasites have very short egg incubation periods and rapid nestling growth.

This implies that Deinonychus used body heat transfer as a mechanism for egg incubation, and indicates an endothermy similar to modern birds.

The phenology of this pest may be summarized as follows: (i) Prediapausing larvae: they emerge and feed gregariously in August after about three weeks of egg incubation.

Although the smaller, first egg receives less favorable incubation, it was found that egg-size dimorphism affects the hatching pattern in Snares Penguins instead of egg incubation position.

In many brood parasites, such as cuckoos and honeyguides, this short egg incubation period is due to internal incubation periods up to 24 hours longer in cuckoos than hosts.

In wild birds, egg incubation is a normal and essential phase in the process of reproduction, and in many families of birds, e.g. pigeons, the eggs are incubated by both male and female parents.

They may well fly more than 100 km out to sea to feed when during egg incubation, but when provisioning the young, they forage closer to the nesting grounds, some dozen kilometers away, and often in shallower water.

While a rafting voyage of four months or more might seem implausible, the ancestors of Brachylophus may have been preadapted for such a journey by having water requirements that can be satisfied by food alone, as well as comparatively long egg incubation periods.

The thin nature of the eggshells of these larger species of moa, even if incubated by the male, suggests that egg breakage in these species would have been common if the typical contact method of avian egg incubation was used."
