Vulnerable Winchell's kingfisher or rufous-lored kingfisher (Todiramphus winchelli), Vulnerable Historical relevance The mountain was the site of the First Battle of Bud Dajo during the Moro Rebellion of the Philippine–American War in 1906, which culminated in the killing by U.S. forces of over 800-900 villagers, mostly civilians, hiding on the crater of Bud Dajo. The event is known as the Moro Crater Massacre. The killings, which disrespected the mountain and the spirits, caused massive outrage among the native people as Bud Dajo is a sacred site. The five-day Second Battle of Bud Dajo in 1911 ended with fewer casualties through negotiations, persuading the majority to return home.
