Animal Gestation and Incubation

The gestation period varies from 33 days in the smaller species to 60 days in the larger species, but is approximately 44 days for the eastern gray squirrel.

Hawks do not gestate. It is rather called incubation, where the eggs incubate via the mother and/or father hawk laying on the nest keep the eggs warm until they are ready to hatch. This takes around 30 days, though actual times depends on the species.

The gestation period of an ant is between 69 and 78 days. However, this time period can vary depending on the individual ant.

It depends on the species. Some have a gestation period of less than 3 to 5 days while others have a gestation period of over a week or two.

The gestational period of a rabbit is 28 to 31 days (that's from the time of breeding to the time of birth of the litter).

Additional facts regarding rabbit reproduction: A female rabbit reaches puberty around 6-8 months and can become pregnant as soon as she does. A male rabbit reaches puberty around 5-6 months and can impregnate a female as soon as he does. A female rabbit can become pregnant the very same day she gives birth. A litter size is generally 1-4 kits (baby bunnies) for smaller breeds, 5-8 for medium breeds, and can be as high as 10 or 15 for larger breeds.

The gestation period for Tigers is 16 weeks. The litter size usually consists of around 3 to 4 cubs. Cubs weigh approximately 1 kilogram (2.2 lb) each, which are born blind and helpless. The females rear them alone, sheltering them in dens such as thickets and rocky crevices. The father of the cubs generally takes no part in rearing them.
First of all, babies stay in the mothers uterus (if they were in the stomach, they would be dissolved). The gestation period (time of pregnancy) of a tiger is 104-106 days.

Female zebras do not reach sexual maturity until they are a few years old. Once impregnated, the gestation period is usually 10-13 months.

Gestation for terrier dogs is approximately 2 months give or take a few days. A Boston terrier gestation will be 63 days, give or take 5 days. she needs to have an ultrasound done at 55 days, to make sure she doesn't need a C-section, as about 1/3 of Boston terriers have to deliver by C-section.

Usually between 62-65 days,62-63 is usually when though

As an prior owner or breeding guinea pigs, I have noticed the animals often birth late in the evening or early in the morning. As nocturnal animals it makes sense, but it is strange that they often do not give birth during sleeping hours for humans. The tummy of the pig begins to have visual indications of the babies movement as delivery approaches. If you are looking at a short haired pig, then you can often see moving areas of the tummy to help you estimate how many will be born. When you are able to see these movements birth will occur during the week. Other than these indications you will hear squealing from the babies and any other pigs in the cage during the birthing to indicate it is happening. Also, if you know the day of conception you can calculate the date of delivery as would be done in humans.

150 days (5 months)

a female will carry her pups for about 60 days, 3-4 months at the most.

The gestation period of a pig is 3 months, 3 weeks and 3 days. Really!

The gestation period is around 10 to 12 months. Females typically give birth to one calf every two to three years at the start of winter. The new born is 2.5 metric tons heavy and is around 7 meters long at birth. He drinks nearly 400 liters of milk every day and gains around 100 kilos of weight almost every day when he grows.

There is a variety of people that are involved as a mystery shopper. College students to the eldery are always needed as a mystery shopper, it is a great way to get items for free or a low cost.

The gestation period of a rhinoceros is 16 months.

Seagull eggs are laid and nested two to three at a time, and it takes about 26 days from laying to hatching. It really depends on the gull species. But for herring gulls, the above guideline is fairly accurate

i just read that the gestation period for barn swallows is 60 days. A pair made a nest on our boat with 4 eggs in it so we were hoping it would be a very short time because we feel guilty using the boat even though it is 94 degrees outside!

super is the cali the fragalist is icky part to know more if Iam wrong go to poptropica.com

A femalewhite tailed deer has a gestation period of 200 days. Other breeds of deer have pregnancies as short as 160 days. So about 5.3 months to 6.7 months. Hope it helps! :)

The gestation period for opossums is generally 11-13 days. However, they do stay in the mother's pouch for about 60 days.

The gestation period for a cow is 285 days. For a goat, it's 150 days.

Pigeons do not have gestation periods because they do not give birth to live young: they lay eggs, like any other bird. Thus, the incubation period for a pigeon is 17 to 19 days.

Mine left the nest in two weeks after hatching but I didn't see them go! Kev Gould.
