Justification:
|
Prior to the 1980s, recorded from multiple sites across the central and western archipelago, but currently only known from western Fernandina and southwestern Isabela after targeted surveys. Based on total reduction in extent of occurrence over the past thirty years, mean population decline estimated at 30 to 50% per ten year interval over that period, with presumed cause of decline (El Niño) persisting and probably exacerbated by climate change. This species assessed as Vulnerable.
