Live specimen in Mount Santa Rosa
|Common Name||Guam Broadbill and Chuguangguang|
The Guam flycatcher or Guam broadbill (Myiagra freycineti), is an extinct species of monarch flycatcher in the Monarchidae family. It was endemic to Guam, where it was known locally as the chuguangguang.
Although common on Guam as recently as the early 1970s, the flycatcher's population went into a rapid decline due to predation by the brown tree snake (Boiga irregulars), which was introduced to the island in the 1940s. The last sighting of the flycatcher was in 1983.
Given the small size of the island, the complete absence of recent sightings, and the universal presence of the brown tree snake in the bird's former habitat, the Guam flycatcher is considered extinct.
