Neotoma bryanti bunkeri Burt, 1932:181

Bunkers woodrat, Bunker's woodrat, Coronados Island woodrat



Taxonomy & Nomenclature

Synonym/s: Neotoma bunkeri Burt, 1932:181


Conservation Status

Extinct or invalid

Last record: 1931 or 1932; 1931 (Fisher & Blomberg, 2012)

IUCN RedList status: Extinct


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


Biology & Ecology




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