In this, the second image of this eagle-feeding sequence, a mature eagle shows off its six-foot wingspan to a young member of the family. A vivid sunset turns the island just behind it to gold. A mature bald eagle has a wingspan of six or seven feet. The largest bald eagles are found here in Alaska. Female bald eagles are twenty five per cent larger than males. This eagle in flight might well be the mother of the immature eagle waiting on the rock. At this time of year, the immature eagles are being taught how to hunt by their parents.
