Premiering on PBS Sunday, April 1 at 8 p.m. (check local listings) the NATURE episode UNFORGETTABLE ELEPHANTS features Martyn Colbeck's stunning film and still photos of African elephants, which he has documented for nearly 20 years. Colbeck earned the trust of a matriarch named Echo and her offspring, and with that trust, privileged glimpses like this scene: the nighttime birth of Echo's calf Ebony, delivered after a 22-month gestation. UNFORGETTABLE ELEPHANTS is part of the 25th anniversary season of NATURE, the Peabody and Emmy Award-winning series produced by Thirteen/WNET New York for PBS.
