Christopher "Ducky" McCrae is sixteen years old and attends Vista school in Palo City, California. He is sensitive and thoughtful and would do anything for a friend (mostly this consists of giving them rides in his car). Most of his close friends are thirteen-year-old girls, including Sunny Winslow, Dawn Schafer, Maggie Blume, and Amalia Vargas. His best friends used to be Alex and Jason, but Alex is hard to stay close to due to his depression and Jason, who now goes by "Jay", became a macho jock and doesn't have much in common with Ducky anymore. Ducky's parents travel often for humanitarian work, particularly in Africa, leaving Ducky and his older brother, Ted, alone in the house for months at a time.
Ducky works at Sunny's father's bookstore.
Ducky's first appearance is in California Diaries #1, Dawn, and he narrates California Diaries #5, #10, and #15 (Ducky, Ducky Diary Two, Ducky Diary Three). He is mentioned in main series #114, The Secret Life of Mary Anne, when Dawn buys him a print of some ducks for Christmas.
