Las Vegas hotel loses dolphin tenant!

Eyewitness News has learned that a dolphin has died at the Mirage. The cause of death is under investigation.

"The Mirage lost a very special member of our family over the weekend. Sage, one of our female dolphins in the Dolphin Habitat, died Saturday morning. Sage was born in the Mirage Dolphin Habitat on May 21, 1997. Our Animal Care team is currently working to determine a cause of death," said Gordon Absher, company spokesman.

Correcting earlier reports, Absher says 13 dolphins have died at Siegfried & Roy's Secret Garden and Dolphin Habitat since the attraction opened with five dolphins in 1990. He says that number included five that were stillborn or died shortly after birth.

The dolphin habitat offers tours to the paying public, birthday parties, "trainer for a day" and group tours. It can also be rented as a setting for private events.
