Nyctophilus sp.

There are four species of this genus found in NSW; however only
Nyctophilus geoffroyi (Lesser long-eared bat) and
Nyctophilus gouldi (Gould’s long-eared bat)
are possible to find in the areas where these recordings are made.

It is probably not possible to separate them by echolocation:
