Video stills from a very distant bird at Richmond Lake, Rockingham south of Perth in February. First thoughts were Whistling Kite but it seems very bulky with really long wingspan. Sea Eagle?
Looks like a Whistling Kite to me too
It looks like a Whistling Kite to me. Shape and wing pattern is wrong for a sea eagle.
I have read the entire thread, and it seemed to me that the sea eagle hypothesis was solidly shot down at the end?
