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.
Reproduction. 1  Canada geese usually begin nesting at three years of age. 2  Adult pairs usually stay together for life unless one dies. 3  Between one and ten, but normally five to six eggs are laid in the nest in March, April, or May. 4  Eggs hatch after 25 to 30 days of incubation. The young, called goslings, can walk, swim, and feed within 24 hours. Both parents (especially the gander) vigorously defend the goslings until they are able to fly, which is at about ten weeks. The young geese remain with their family group for about one year. If the nest or eggs are destroyed, geese often re-nest in or near the first nest. Canada geese can raise one clutch per year. Longevity and Mortality . Predators of Canada geese and their eggs include humans, coyotes, raccoons, skunks, bobcats, and foxes, as well as gulls, eagles, crows, ravens, and magpies.
