The Pacific Loon's head is black which extends down the back of its neck and back where there are some mottled white spots. On its underside the color is white extending from its bill to its belly. The Pacific Loon feeds mainly on small fish and other aquatic life. Reproduction Pacific Loons are monogamous as long as the relationship is producing offspring. Breeding takes place in the spring and summer and is relatively noncompetitive once a mate is found for the males defend territories and mate with the same female each year.
Loons are extremely awkward on land and venture out of the water only to nest.
Broods usually include a total of two eggs, one of which is laid a few weeks before the second. This first egg also is the first to hatch, and it is brooded while the other egg is incubated. The older offspring assumes the dominant position in the nest and will be the first to be feed throughout its development. Behavior When loons have young, they will often transport them on their backs to decrease chances of predation and to keep the young chick warm. The young are completely dependent on their parents for the first 5-7 weeks but by the eighth week it will have developed fishing abilities to go off on their own.
