Thanks to conservation efforts by states, landowners and others, the <strong>Delmarva Peninsula fox squirrel</strong> -- native to Mid-Atlantic states -- is no longer at risk of extinction. One of the animals included on the first list of endangered species nearly a half-century ago, the squirrel was set to be removed from the list in December 2015, the U.S. Department of the Interior said.

A <strong>gray whale</strong> calf emerges from the waters off Baja California, Mexico, in 2010. The Pacific gray whales have been protected since 1970 and are at the center of a growing whale-watching industry. They were removed from the endangered species list in 1994, although climate change has impacted their food chain and caused their numbers to decline again in recent years.

The <strong>Virginia northern flying squirrel </strong>was in danger of extinction in 1985, when scientists documented only 10 remaining animals. But its population made a comeback, and the squirrel was removed from the list in 2013. The squirrel is native to West Virginia and, yes, Virginia. It doesn't really fly, although membranes between its legs serve as "wings" and let it glide from tree to tree.

The <strong>American peregrine falcon </strong>was classified as endangered in 1970 after its population was decimated by pesticides. By 1975, there were only 324 known nesting pairs of American peregrine falcons. Conservation efforts helped them rebound, and they were removed from the list in 1999. There are now more than 2,000 known breeding pairs of the birds in North America.

The <strong>bald eagle</strong>, a revered American national symbol, was famously endangered for 40 years. By 1963, only 417 known nesting pairs of bald eagles remained in the U.S. Vigorous conservation efforts revived the handsome bird, and it was removed from the list in 2007. Today there are more than 10,000 nesting pairs of bald eagles in the contiguous United States.

The <strong>Aleutian Canada goose</strong>, found in Alaska, Canada and the Pacific Northwest, numbered only in the hundreds in the mid-1970s. But efforts to recover the bird population were successful, and biologists estimated that there were 37,000 Aleutian Canada geese by the time the bird was removed from the list in 2001.
