One of a pair of nesting bald eagles launches off the nest at Potter Marsh in south Anchorage, AK on Saturday, April 1, 2015.

For all their majesty and dominance, an eagle's first year of life can be tough. The mother may lay anywhere from one to three eggs, but usually just one chick -- often the first to hatch -- survives to leave the nest. On average, each baby eagle has less than a 50 percent chance of making it through its first year of life; some experts place a juvenile eagle's overall mortality rate at up to 75 percent.

So far, so good for the family of bald eagles that photographer Bob Hallinen has tracked since April as they incubated at least one egg near the backside of Potter Marsh in Anchorage. The adult pair then nourished the resulting ball of gray fluff into a healthy, chocolate-brown juvenile that has, to all appearances, successfully left the nest.
