Interesting and I think notable. Well this must
happen if you and others record it. So although that happens, I'd suggest
it isn't the normal or usual hunting behaviour. A Crimson Rosella must be well
into the infrequent upper limits of their prey size range and they usually hunt
alone with quick dashes after flying small birds, small bats and big
insects. I have spent a lot of time watching this species around nest sites
and regular roosts. I haven't noticed them hunting in pairs, although courting
pairs indulge in chasing and juveniles regularly follow parents on hunting
forays. At this time of year here, the young are recently fledged and the
parents are busy catering for peak needs and training them in hunting. The Hobby
is also known to take advantage of flushers like butcherbirds, goshawks,
etc. The Peregrine Falcon is known to regularly hunt in pairs.
