Where I live - just outside Canberra - the usual cause of mobbing by small
birds is a leg-challenged reptile.

The local small passerines will also have a go at our Frogmouths
occasionally (but ignore them most of the time), but that seems to rely on
visual cues as the birds are usually silent in daytime.  In the past a
mobbing flock led a group to a Powerful Owl in the ANBG but the recent
visitor to Turner (North Canberra) hasn't been reported as being hassled to
my knowledge.
