Fowler died Wednesday at his home in Norwalk, Conn., according to a statement from his family obtained by The Hollywood Reporter. No further details were provided.
Fowler is survived by his wife, a wildlife artist, and the couple’s children Mark and Carrie, per The Hollywood Reporter.
Fowler co-hosted the Emmy-winning nature series alongside fellow zoologist Marlin Perkins starting in 1963 — when the show launched — until Perkins’ retirement in 1985. Fowler then hosted solo for several years and returned for its revival in 2002.
He also served as a wildlife correspondent for NBC’s “Today.”
