Maternity colonies can consist of several hundred animals (Rhodes and Richards 2008). Females give birth to a single young. Generation length is likely to be at least five years (N. McKenzie pers. comm.). The species moves northwards in the southern winter.

Threats [top]

Major Threat(s): There appear to be no major threats to this species in the short term. Global warming may be a serious threat to this species in the future because the species is tied to temperate Australia - in 70 years, the species' range is expected to have disappeared from south Australia (N. McKenzie pers. comm.).

Conservation Actions [top]

Conservation Actions: This species is known to occur in a number of protected areas. Further studies are needed into possible threats to this species.
