RICHMOND — A pair of nesting bald eagles on Maine’s Swan Island has produced the first documented case of four eaglets in the same nest in the state’s history.

Maine Department of Inland Fisheries and Wildlife biologist Kendall Marden says the eagles had unsuccessful nesting attempts over the past two years before producing four eaglets at the Swan Island Wildlife Management Area in the Kennebec River near Richmond.

Maine officials say there have been only three other documented cases of four eaglets in a single nest in the United States.

As recently as 40 years ago, bald eagles were battling against extinction.

The bald eagle was removed from Maine’s list of threatened and endangered species in 2007 and there are now more than 500 nesting pairs in the state.
