June 2, 1970 The Tinain monarch was listed under the U.S. Endangered Species Act, which helped the bird on the long road toward recovery.

September 21, 2004 The Tinian monarch's population had rebounded, and it was removed from the endangered species list.

May 2005 The U.S. Fish and Wildlife Service released a post-delisting monitoring plan for the Tinian monarch.
