John,
The file I listened to, had 3 sounds that I could define.
The most prominent sound was I assume the cricket (sounded like it to
me), the second sounded to me to be either crickets or tiny wrens,
wrens was my immediate thought, I hear them around me often at dusk
and dawn, the third sound that "flew" across the field certainly
sounded like the bats I hear to my ears.
I am not a bat expert but as far as I know we only have two local bats
that are within our audible sonic range - the Yellow-bellied
Sheathtail Bat - Saccolaimus flaviventris and the White-striped
Freetail Bat - Tadarida australis.
The rest are well above our hearing range, so to a degree it makes ID
a little easier.
Cheers
