A Bowman's capsule is part of the filtration system in the kidneys. When blood reaches the kidneys for filtration, it hits this area first, with the capsule separating the blood into two components: a cleaned blood product, and a filtrate that is moved through the nephron, another structure in the kidneys.

The incubation period for wood ducks varies, but is usually between 28 and 32 days. The entire clutch hatches in less than 24 hours. The hen will leave the nest box with her new brood on the first morning after the initial egg was hatched.hen the entire clutch of eggs has been laid, the hen will begin full-time incubation. This assures that all the eggs have a good chance to hatch together on the same day. During the incubation period, the hen will leave the nest box twice daily to feed (morning and evening) for about 30 minutes.
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.
