Justification of Red List Category
This species formerly occurred on Guam, but became Extinct in 1983. Predation by the introduced brown tree-snake was the cause of its extinction.
No extant population remains.
Myiagra freycineti was endemic to Guam (to USA), where it was common until the 1970s (Jenkins 1983). However, it plummeted to extinction (Collar et al. 1994) in 1983, along with most of the island's native birds (Jaffe 1997).
It inhabited forest.
Its rapid decline to extinction was due to the depredations of introduced brown tree snake Boiga irregularis (Savidge 1987).
