Neotoma bryanti bunkeri Burt, 1932:181

Bunkers woodrat, Bunker's woodrat, Coronados Island woodrat



Taxonomy & Nomenclature



Conservation Status

Last record: 1931 or 1932

IUCN RedList status: Extinct (since removed)


Expeditions in March 1989 and June 1990 failed to confirm the continued existence of this species, and it is probably extinct (Smith et. al. 1993). However, it is considered a synonym of N. bryanti bryanti by (Patton et al. 2007) and as a consequence has been removed from the IUCN's RedList.



Coronados Islands, Baja California Sur, Mexico






Only known from 6 specimens (Smith et. al. 1993).
