PROVINCETOWN, Mass. (WHDH) -
The North Atlantic right whale Wart has returned to Cape Cod Bay, the first sighting since April 2013.
Researchers have been keeping track of the whale for the past four years and are excited to see her return.
"The sighting of Wart reminds us that Cape Cod Bay is important both to a large part of the remaining population of this extremely rare whale and also to the mature female whales on which the future of the species depends," said Dr. Charles Mayo, Director of the Center's Right Whale research program.
Wart is a part of an endangered population. There are only about 500 right whales documented.
The female whale was freed from an entanglement by the Center for Coastal Studies (CCS) in Provincetown in 2010. She was spotted in Jan. 2013 with a newborn calf.
The CCS have spotted two other right whales this season: Catspaw and Piper.
