Ad. Bowman's capsule and the glomerulus form a unit called the renal corpuscle, in which the initial process of filtration occurs. A small artery carries blood into the glomerulus, where it is filtered at high pressure through two layers of cells before the remaining blood leaves through another artery.d.

Females lay 2-9 dull white oval eggs in each clutch (a set of eggs laid at one time. Canada geese lay 1 egg every 1 to 2 days; the eggs are usually laid early in the morning. Incubation takes an average of 28 days, with the female sitting on the eggs and the male guarding the area around the goose.he male is booted out of the clutch at one year of age, and he joins the group of single, young males. Number of eggs produced: 4 to 9 (average is 5) Gestation Period: 28 to 30 days (Average is 28) Weaning: No weaning period.
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.
