Are you sure? I've heard Black Kites in the NT make calls that sound very
similar to the characteristic territorial(?) call of Whistling Kites.
rlack Kites seem to give a softer, more slurred version of the call, but I
suspect Whistling Kites do this sometimes too.
HANZAB quotes Debus as saying: "more tremulous quality, not descending
so vigorously and staccato notes not ascending so vigorously as in
Whistling Kite. The sonagrams in HANZAB (Black Kite C And Whistling Kite
A) have strong similarities. Surprising given they are from different
genera.
