Breeding adults are in length with a wingspan, shaped like a smaller, sleeker version of the Great Northern Diver.

Breeding adults are like a smaller sleeker version of Great Northern Diver / Common Loon.

Breeding is also possible: Males attract females to small cave or hollow, then guard eggs after fertilization through hatching ( 4 – 8 days ) until fry are free swimming ( 4 – 6 days after hatching ); the aquarist need only supply a suitable cave, food, and one of each sex.

Breeding habitat used in Russia are similar, though they can be found nesting in less likely habitat such as steppe and even semi-desert, so long as water is near.

Breeding males are fiercely territorial.

Breeding is opportunistic, usually from August to February in the fertile south, anytime after rain in drier areas, and multiple broods are common when conditions allow.

Breeding responsibilities, nest building, incubation and chick feeding, are shared between both sexes.

Breeding adults are easily told apart by the amount of naked facial skin, which does not noticeably extend beyond the eye in P. pelagicus, but extends to above the bill and above and behind the eye in P. urile ; the latter species also has larger crests.

Breeding individuals store energy rich lipids in a sac anterior to their stomach which are used to either sustain themselves while incubating their single egg, to feed their chick, or can also be used as a defensive mechanism when caught by a predator as do many other Procellariformes.

Breeding males are unmistakable, with the namesake largely blue plumage and a grey bill.

Breeding seasons may be affected badly if the weather is cold and wet between May and July, particularly if this coincides with the emergence of the caterpillars on which the nestlings are fed.

Breeding occurs in May, and depending on the amount of prey available, clutch sizes range from 5 to 14 eggs, which are laid singly, approximately every other day over the course of several days.

Breeding is fairly slow as the young do not reach full size until they are two or three years old.

* Breeding: Backyard breeders are a leading cause of overpopulation because they usually produce more dogs than they can sell and often produce animals that do not meet stated breed standards.

Breeding females are restricted to one litter per year and six per lifetime.

Breeding females are more active than nonbreeding ones during the late night and morning hours.

Breeding habits are also variable.

Breeding adults are spotted gold and black on the crown, back and wings.

Breeding adults are brown with dark brown streaks on top and white underneath.

Breeding habitat is typically large areas (> 160 acres ) of dense young jack pine ( Pinus banksiana ).

Breeding is by egg scattering and takes place close to the bottom, near or within areas of dense plant growth.

Breeding habitat is seepage water in open fields or woods.
