Hello Michael,
Not sure what kind of suggestions you are seeking. Given that Sparrowhawks like
to nest in conifers, I wonder if the trees contained the nest of the
sparrowhawks and what you had was two parents with two of their kids and they
were agitated by the presence of somewhat big and dangerous looking YTBC. Not
being there to get more details, that is my suggestion. I doubt you would have
two families of sparrowhawks together.

Subject: [Birding-Aus] Sparrowhawks vs YTBCockatoos
Yesterday in Mulgoa Valley, six YTBCs were screeching and wildly flying into
and around a Radiata pine whose cones were providing their lunch.
Investigating, there were four (4) Sparrowhawks noisily attacking the
cockatoos, which after about five minutes departed.
Couldn’t tell age or sex of Sparrowhawks but presumably they were two families,
unless there was a single clutch of two or three with one or both parents ? Any
suggestions ?
