Population justification
None remain.
P. dubius, endemic to San Cristóbal in Ecuador's Galápagos Islands, has not been recorded since the 1980s despite recent searches and is now considered extinct (Wiedenfeld 2006).
The species was previously found throughout the island of San Cristóbal and was likely similar in habits and ecology as other Pyrocephalus species.
It seems likely that either the introduction of rats, the arrival of avian pox or potentially the bot fly Philornis downsi, or some combination of all of these and potentially additional introductions caused the decline and extinction of the species.
