Anyone with good eyes want to have a guess?!
Entry level camera is on my current wishlist...
My thought is the related factsheet.
The Black-Shouldered Kite (pictured on her usual spot) launched a preemptive warning attack, for getting too close to her fledgling.
Brown Goshawk?: relatively long, slightly rounded tail.
Good call Woko.
I went the other way because of wing shape/position and markings which are similar.
The slightly rounded tail is the key here I think.
Also I recall thinking that it had a stubby, thick head which also favours your pick...
Cheers mate!
