Breton Island, located at the southern end of the Chandeleur Islands, supports one of Louisiana?s largest historical brown pelican nesting colonies. Although the brown pelican (Pelecanus occidentalis) was delisted as an endangered species in 2009, nesting areas are threatened by continued land loss and are extremely vulnerable to storm impacts.
