Cougars become sexually mature at about 24 months of age. However, sexually mature cougars seldom breed until they have established a home range. Cougars have a gestation period of approximately 92 days. They will generally give birth to between one and four kittens, although two or three is typical. Kittens (also called cubs) weigh just over a pound at birth. Until they are two weeks old the kittenâs eyes and ears are closed.
The length of a gestation period varies from bird to bird. Oftentimes, larger birds require longer gestation periods than smaller birds.For example, muscovy ducks -- one of North America's largest ducks -- require approximately 35 days for gestation, while smaller ducks have gestation periods of less than 30 days.Smaller perching birds, such as northern mockingbirds, have a gestation period of only 13 to 15 days.A smaller bird of prey, the red-tailed hawk, has a gestation period of 28 to 32 days, while the California condor needs at least 56 days for the gestating period.he length of a gestation period varies from bird to bird.
